Many years ago I worked for AMC and UCI in the UK. In the first multiplex cinemas we always used JBL speakers in a 2 way configuration. 2 x 15 inch and horn HF unit for the three stage, front speakers. I can see the same issues here as I encountered all those years ago. That miss match and suck out at the crossover frequency. No amount of EQ could get rid of it. The upper HF roll off could be EQed out but not an issue in cinema use. Basically a 15 inch does not go high enough and horn does not go low enough. This is also the same in other makes, EV for example. The answer was to go three way. WOW what a difference, almost no EQ was required. Voice was so natural and clean. Crossing over at the 600/700hz is the worse possible frequency, right in the voice region. The colour of the sound at crossover was dreadful. Cinema sound can be almost all voice. You could here voice jumping from the LF to the HF units. Used to drive me nuts. Looks like if you throw enough money at any problem it can almost be fixed. Regarding tax!! I get taxed on all my US viewers and then pay tax on all the income again here in New Zealand. Who said life is fair?

Thanks for this review Erin!! The 4367 is a spectacular speaker. Of all the speakers I have owned in the past 30+ years, these are by far my favorites.

I've had a few JBL speakers and they have never let me down. Their engineering is second to none.

Got to give a man his props when he does a great job 👏🏿. Really appreciate the effort and the honesty that you put into your reviews. This is a great template for others to follow, please keep up the great work. 👍🏿

Kudos to James! Side reflections and pristine dynamics. No surprise you liked it.

Excellent test again. Finally everybody will fall in love with a big woofer speakers. The effortless sounding is always amazing, it is one of my dream speaker.

There's a reason countless studios employ 15" two-way mains. These JBLs, w/the new 2216Nd-1 advanced diff/drive woofer, the double driver D2 tweeter, essentially top tier drive units JBL has developed. These are packed with goodness,... their x-overs are tricked up with DC biased caps, air-core coils, wire-wound resistors. Aside from directivity control, I believe the primary attribute is their dynamic transfer function with minimal compression losses. The ability to track the signal responsively, without spectral changes regardless of playback level is vital. That allows imaging and soundstage dimensionality to remain intact irrespective of SPL. It would be fascinating to experience these A/B'd up against a diysoundgroup 15" two-way... or any comparable diy effort of passive two-way. * Erin, your anecdote wrt the hard "ck" sounds ... who knows, but I'm guessing this JBL has more HF capability than most any you've measured/reviewed. More resolving power, low loss, low noise/breakup than just about anything ... so, I'm curious is there's a connection. It's one thing to hear something remarkable, but another thing to be listening for it and hear it again. Merely speculating. This was another good one. Solid work.

Great Review! I have a McIntosh C2600 Tube Preamplifier and a McIntosh MC452 Solid State Amplifier so hearing you mention McIntosh pumped me up about the idea of purchasing a pair of these JBLs. Won't happen over night but perhaps in the next few years. Thanks again!

Shout out to James, really appreciate your time and energy, buddy. Same to you, Erin, as always.

I am surprised by how much more narrow the polar response is on this speaker compared to the M2. I thought they would be more similar, but it's obvious that the horn design is quite a bit different. M2 seems like it would have a lot more room interaction, especially the amount of energy at the sides and to the rear. I have significant room treatment and would assume that the 4367 would sound less open and a little soft on the highs compared to the M2 in the same room. Great accomplishment for a passive design, but it should be great considering their cost. Thanks Erin.

Regarding audiophiles.... "Audiophiles don't use their equipment to listen to your music. Audiophiles use your music to listen to their equipment." -Alan Parsons

Thank you for the deeper dive on reconciling subjective observations with the measurements.

Have a lot of experience with dual 15 with compression horns in my career. Considering the time offset between drivers, the crossover is amazingly smooth. When using commercial speakers like this, using open architecture dsp, I would time align the drivers, even though they have passive crossovers. That always made a huge improvement in intelligibility in the crossover region.

Great point, that audio memory or attention(?) aspect of audio is difficult for me to wrap my head around. So it has been studied that a clear speaker/system will allow someone to 'notice certain sounds' you may not have been able to with other systems. But audio memory/attention being what it is, once you notice 'sounds' on a good system, the brain is easily able then to pick it out on much less 'resolving' systems, even where that sound is very masked/distorted. Which just makes your analysis and data that much more important like you say, because once it's heard, there's no way to tell if that 'sound i never heard before' was actually masked by a problem with the speaker/room or was always clear but just never noticed/focused on.

The response looks good. Reminds me of many songs+tracks that have a similar eq curve

Great video. I’ve always wondered how the vintage JBL’s measure, like the ones from the ‘60’s. I’ve got some and they sound incredible and the crossovers are very simple. I’m curious what their methods were way back then. I imagine it involved tons of listening. I also wonder how they stack up to these.

It's just crazy how expensive these are.

Thanks James for being the man🔥❤🔥

Thank you for the great content, Erin! If I may ask, how would you compare it to the JBL M2? Thank you!

I've heard different things from my system just from better calibration and toeing in differently, I have a thrown together system too. Everything in the chain matters and how you're setting it up matters just as much. I look at reviews for general overview of speakers but I only trust my ear for what's good. This is topic that does need to be discussed more from the KZfaq audio community.

Pretty amazing for a speaker of this size!

Erin, what you heard is the engineers use of compression on vocals. We smash the crap out of vocals and many of the tools we use are quite audible, even if we are careful. The JBL speaker you reviewed, because they are efficient and use a compression driver have effectively "unsmashed" the "k" sound that is usually not so forward in a compressed direct driver "normal" speaker. If you heard that, let me give you something else you may hear. You may also start hearing "reverb tails" These too are "uncovered" by compression driver type speakers. If I ever have an occasion to speak to you, I will detail it bit. It's a lot to write about.

Just noticed after watching this that your Kef Reference 1 Meta review you have a similar level of appreciation and although it's flatter than this and doesn't roll off in the highs as much, or at all with in room, your linearity on axis stuff with the horizonal blue and gray zone does show somewhat rolling off response that is much more subdued. Maybe you do appreciate that or are just sensitive to any boosting of highs at all. Really like your objective/subjective review balance and quest to try and match up the two approaches so they can be related/explained when we have no great way to audition all the options.

Hey Erin. I really love what you’re doing with these reviews (and channel in general). And huge respect for the hardware investment you’ve made! Just a thought about the data in regards to your account of hearing some emphasis in the 6khz region.. nothing really stands out in the SPL, or distortion/linearity data so I wondered if your tests can produce a cumulative spectral decay analysis, I.e. waterfall curve? It’s well known that we are very sensitive to hearing stored energy so perhaps there is a resonance issue at the 6khz region? Possibly a horn related issue? Anyway, really fantastic channel and work you’re doing. I think if you can include the “waterfall” data in your reviews then you’ll be onto a real winner and your tests will really paint a very compete picture of a speaker’s performance.

Hey Erin this was an excellent test, the best one I've seen in a very long time. Isn't it funny that people the moment they see a horn they claim that they hear horn distortion (on a speaker with below 1% distortion) but when they listen to regular dome tweeters, then everything is fine while they are listening to 10%+ distortion ;-)

Another great video Erin. What are you thoughts when you compare the JBL 4367 to the JBL M2?

Basically I think what you're hearing is what Geddes was shooting for in his designs. Limiting room interactivity makes the speaker more resolving. Only using a round oblate spheroid waveguide would have had less vertical anomalies. You should really hear a pair of Summa's I think you'd like them even more. :)

Hello Erin, I am new to your channel and love your honest reviews. However i looked back a good ways in your older videos and i had noticed you've not done any reviews of Rockville audio. I was wondering your thoughts on their bookshelf speakers, subwoofers ect. Again your reviews are amazing and thank you for the great content.

Ahhh hell Erin, im right there with ya brotha! I share in your dream to one day have Mac amps. Where we differ is that I want a set of vintage Altecs connected to em. I would even go with custom re-productions using new transducers/x-overs from Great Plains Audio. The owner was an ex Altec employee with the tooling from the old factory.

Great review and sounds like you have built a super community for one of your listener's to go to such effort. KZfaq concentrate on the numbers but the community is the important part (I think). When I did my research on these speakers they are compared to klipsch cornwall which are loads cheaper. Love your opinion???

Erin - THANK YOU for a fantastic review and your contribution to this community! Quick question: are the resonances between 100Hz to 200Hz an issue? I just happened to be listening to your review of the Heresy IV and realized you had mentioned that bumps between 100Hz-200Hz (that, fortunately, Klipple has the resolution to identify) are enough to ruin a speaker. I wonder if that is just a part of tall-rectangular-ish cabinets. I have a lead on a pair of used 4367s at a good price - but that comment has me concerned. Looking forward to your response.

these look like some awesome speakers.

Relativity is all that matters and this shows in that sssshhhhhh ssssshhhhh part. How do we know if somethin is rising or dippin without a relative frequency taken as a guideline? This is also a problem when you want to draw out an imaginary line. Just my thoughts. Another great one Erin!!!

When I win the lottery I hope to give them a try! But seriously, thank you for the review.

Seems like really nice speakers. To me listening tiredness is due to too much energy in the 3-4 kHz area. I often preferr att lite less on-axis there. Like 1-2 dB. With too much energy there my ears get really fatigued after a while especially with highish volume.

Hey Erin, Just a friendly reminder that many of us are patiently (or not so patiently) waiting for that Kii vs Dutch & Dutch video. 🙂

Hey Erin, dobyou have REW data of your speakers in the listening room? It would be interesting to compare your testing measurements vs what the speakers put out in your actual listening room.

Wow!!!!!!! That’s my speakers!!! Not this pair. My 4367 even has different color. But it’s my favorite speakers. Before I’ve had few speaker pairs that costs 3x more

2 favorites for listening / auditioning- .02 Judy Collins- Farewell to Tarwathie "Kiss of a Rose- - Annette Cantor, Deuter

wow those charts look amazing and they better for that price. Amazing speaker design by JBL.

Erin, do you have a comparison between JBL Synthesis install SCL 6, 7;and 8, and the CBT 70J-1 that you previously tested? Im considering a hybrid system with 6 70J-1 in the bed layer, and 4 Atmos SCL8 (bc they fit my coffered ceilings better). Would you be concerned with mixing the line array tweeters of CBT with horns from SCL-8? Kind thanks in advance.

What you are describing the beginning of this review re The Cars track, is known to perceptual psychologists as the reticular activating system (RAS). When RAS is activated for some reason, we notice things we otherwise would not. So if you listen to something like that Cars track a dozen times not having the RAS activated at the point when those glottal stops were exaggerated, you would not hear it. Then if for some reason, when you came to the same point with your RAS activated, you will suddenly hear it and come to the snap conclusion that the system you just heard it on either achieves "new heights of resolution" or maybe "dumps heretofore unheard level of shit in the playback" depending on whether or not you like the newly perceived effect. Exploiting this psychological quirk explains how audio salesmen convince buyers in a showroom of a certain system's "superiority"--just activate the mark's errr..customers RAS ('just listen to how those Wilson's handle those high hats, Erin") so he hears stuff he's never heard before in an audio system, and frame it so so as to condition him to believe those new things are a significant advance on what he has at home. Out comes the plastic, and the salesman gets to make a house or a car payment!

I almost bought a pair of these 4367 unheard as dealer demos online but bought a pair of Revel 228be instead. I use a McIntosh MC462 amplifier. Edit, 2023 I bought a pair of 4367 lol. My opinion matches this review.

Oh baby that compression test…

Hi Erin ! Have you checked out Meyer Sound for Home Theatres setup .

Hey Erin where can i find Atlantic Technology speaker review if u have any since I saw u post about in on AVSforums

"I don't think anyone can hear it... If you do..... OKAY" You crack me up.

Erin, which brand/model camera do you use?

Oh man, when designing speakers I've often got hung up on a specific thing I noticed. I typically adjust something, feel happy, then weeks later after listing to lots of other songs and systems realise I went too far and back it off.

I have the Affordable JBL Studio 580 and for me they are exceptionals !

Someone send Erin a pair of PSA MT-110. Where most speakers claim a frequency response above 20K, PSA claims 18K. I wonder if they too have a high end roll off like these JBLs and what Erin's measurements and thoughts are.

For 16k, there are many options. If you can pay 16, you can probably pay 20 or more. That opens up even more options. I you had 20k for speakers, would these be on your short list? I couldn't really tell from this review. Thanks!

How do these compare to the jbl ps 12 or 15? I cant find any specific review.

I totally agree with you about music choice when auditioning speakers. No one should review/evaluate a speaker with music they don’t like.

Please try to demo the Klipsch CORNWALL IVs....

Dream speakers 🤯✨✨

Hearing your concerns about the hard "G" and hard "C" sounds, I think know just what you are talking about I have made things sound like that intentionally, in fact. I'm a recording/ mix engineer, and I know that moderate to heavy compression with a slow-ish attack time and a high ratio will emphasize the leading edge of hard transient sounds. Basically, the compressor is reducing the overall dynamic of the track being affected by reducing the volume of loud passages. (That happens over a very short period of time, so don't think of it a turning down the volume knob when things get loud it's still typically too fast to hear it as volume reduction.) Hard compression with a slow attack will let the first few milliseconds of transient exceed the threshold before the compressor begins to work. When the compressor does begin to reduce the level of the track, the transients that sneaked through *before* the the compressor attack are effectively accentuated. It is done *all the time* with snare drums to accentuate the crack. It's used to make a guitar sound like it is being strummed more aggressively. Whether or not it was done intentionally by the person who mixed the song is anyone's guess. The biggest down side to listening to someone else provide their subjective opinion about the performance of a loudspeaker is that there are well-recorded, mixed and mastered songs. And there are songs recorded, mixed, and/or mastered poorly. A theoretically "perfect" speaker reproducing exactly what it is fed will accurate exhibit the uniqueness of every recording. I don't think someone's subjective impression is worthless if you trust the reviewer, but it's hard to know exactly what is being critiqued. That's why the more detailed a reviewer is about specific sounds in specific songs the less weight I give that part of the review. Someone far more clever than me once said that "talking about music is like dancing about architecture". It's a pretty accurate comment. The more broad and vague comments regarding how a speaker sounds in comparison to another speaker, while judging the exact same material, gives me a better idea of what the loudspeaker might actually sound like. Or at least an idea of what the reviewer likes. As usual, awesome review. For now anyway, discussing the objective measurements of a speaker provides a lot more usable and useful information. And measuring speakers is a whole lot more involved than just commenting subjectively. But you knew that or you wouldn't do these reviews. I really enjoy watching your videos. Thanks!

Excellent review. Oof, the price...😞

Shout out to James!

Is there any chance the 4319 would be ok in a 2 channel only home system. They are only 2k each.

Erin, I think you are making a mistake by not paying enough attention to the CSD mesurements. I've seen two-way speakers with very flat frequency response that had emphasis on some upper midrange notes. And then I've learned that was due to the midbass cone breakup "ringing" well above the crossover frequency. Such things are clearly seen on the CSD plots but could be not noticeable on a frequency response.

seems to be a 2 way instead on 3 or 2.5 way most klipsch do the same thing

Looks like your catching up with me... 15inch bass driver speakers sound so good because they have narrower directivity. Human hearing has evolved to identify the physical size of a object emitting a sound by using the directivity index at lower frequencies as a guide. That's why a long throw 10inch bass driver in a 10inch wide cabinet doesn't Have the excitement factor of a 15 inch bass driver in a 18 inch wide cabinet. you don't get a fight or flight response from it as the adrenaline response is automatic to a larger moving object.

Not noticing it on other speakers until it was "pointed out" by these comes under the heading of "revealing". The highest note on a piano (C8) is 4186 Hz. A guitar doesn't even get to 1000 Hz. 8000 Hz is a very high musical frequency with very little musical information there. Just because (some of us) we can hear to 20,000 Hz doesn't mean there's much information up there to listen to.

I'd love to see you demo some mcintosh amps 🤘

Get yourself a pair of the JBL L222 disco's, you won't be disappointed my friend!

Does the port placement, front/back, actually make a difference in the measurements?

Erinnn, can u do a Atlantic Technology speaker

Gr8t review. Subjective and objective together. I learnt alot thanks.

Did you prefer the 4367 over the M2? Great channel by the way.

Can you review the jbl Studio 590 please

How long until Danley's Hyperion comes out? They have any development loaners available?

This is an $8,000/$16,000 passive speaker/pair, right? What makes it rock vs a Genelec 1238 or 8361? This might be a great speaker, but in relative terms, what does it beat out? Always curious how we can avoid recommending too many things and I think relative rankings would help that. This speaker doesn't seem to be state of the art, nor does it seem to be the best price to performance wise. They seem like a good speaker to build into a wall, and they aren't bad per sey, I just don't see what would motivate someone to buy this over anything else. Thanks for the review, and I'm glad you listened and explored why you were hearing those "kk" noises. I used to go back and forth between headphones and one might reveal something new but then I could hear it on the other. Makes it really hard for purely subjective reviews.

Another great speakers JBL 4365, look the same, about 190 lbs each.

should check out the JBL M2 with the BSS active crossover management system.

Hmm that dip at 700 to 1k looks very similar to the "Arnie Newdell Dip"

I should also state something very interesting (at least to me) is having played with a few waveguides now, the sound in each wavguide presents unique qualities that CANNOT be eq'd out. They're inherent to the waveguide.

any idea if a pair would measure similarly? I hate it when one speaker is markedly different from its matched pair. The reason i loved Snell was they were factory tuned to be within 1db of each other across the spectrum. BTW, the measurement on this speaker is very similar to many of the Sonus Faber higher end speakers, but they dont have the notches as much. But the overall "tuning" or response is quite similar.

I’m confused. Erin shilling “my” 4367 like some golden ear audiophile ))))

The 5k hump could be a higher "Q" peak that the test system didn't have high enough sampling rate to catch, or smoothing was too broad. That would explain why it only showed up at certain times. The other sharp peaks may provide some clues. Another explanation could be a horn resonance (hi to low air impedance) or phase plug issue. Dual fft analysis could identify the problem.

First.... gotta watch now !!! Love JBL's sadly I'll probably never own any.

jbl 4367 vs klipsch cornwall ? what do you think?

I bought these for myself They play cool The terminal says Made in Indonesia 6ohm

Btw for people who are somewhat concerned about the wiggils in the crossover region in the compression test, that's the crossover components being pushed hard. Yep ladies and gentlemen, this speaker is more likely to be limited by the crossover components of all things. You don't see this everyday.

I’m with you on music. The “audiophile music” turns me off.

Is the black finish a real wood veneer like the Walnut finish?

Interesting that the woofer resonance doesn't seem to show up here that stood out in the M2 measurements. Maybe it was something with the particular M2 you measured.

$16500? if you bought the best 15woofer you could find a how much would that be €400 each ? the best compression driver and horn $1500 each few quid for a box and crossover seems like these are marked up by about $10000 ?

I'd love to see the JBL C211 reviewed. If I ever get new speakers for home theater. It's probably going to be the C211.

Here's a cool dude.

I bought them for $6500 a pair, they are a super product!

Woah! That price tag though. I love hearing about new good speaker designs but for the price geez, way out of my league. I just bought a 2018 SUV for less lol

Until now you said you like wide directivity. Have you maybe changed your mind?

$16,500? Holy...

If I had $16k speakers I wouldn't ever want to risk damage by even moving them let alone loan them out.

me: oh wow he likes a JBL let me look at the price me: oh

I chuckle when people react to the price. Everything has a value and everything has a cost. You never know when an opportunity finds you and you wind up driving home with a pair of these or some McIntosh amps that you cannot believe how you lucked into them. My point, quit thinking about the price of something and simply enjoy it’s existence. God may place something in your possession you never thought possible.

Of course it's the mix

A JBL 15". driver can have 100x100 degree despersion at 1K before they start to beam badly / as they are in the old 4430 & 4435 monitors, their best ever monitors with time alignment. The wave length of 1000hz is just over a foot, or 34cm to be exact. X-over design will also impact the despersion characteristics. Although that peak you describe may be in the recordng, most horns would exaggerate that by nature, along with other charcteristics horns impose on sound with their harmonics / distortion. The frequency drops right after that described peak and likely because of this drop it would emphasis the frequency range right before it. I owned custom redesigned JBL 4435's for a long time and they had the lowest 2nd, 3rd, 4th, etc, harmonic distrotion of horns at that time because of the short throat & horn design. Those bum shaped horns still have the least "horny" sound to this day, yet they still had some "horn sound" when compared to dome mids & tweeters. One thing I can agree with, old rock sounds best on those speakers likely because most Rock was and still is mixed on similar style horn loaded speakers to this day. BTW: Jazz and other genre's is NOT "Audiophile" music, just different genre's which happen to be much better recordied in general than rock! / unfortunately
