Danny -I am really glad you are going to provide some sound clips. I completely understand the limitations of doing this but some information for us listeners is better than none. The clips, accompanied by your own thoughts and input, is better than just the measurements, in my opinion. I really believe that better quality parts lead to better sound (assuming a good design) and I would really love to hear more comparisons (especially vs. your own designs). Thanks very much for all your hard work. It is really appreciated.

Great to hear sound clips coming, will be a game changer for the channel imo.

Hi Danny thoroughly enjoy watching these vids. It really shows up some of these manufacturers.

Nice work!! I'm enjoying these videos more and more. I went to a hifi expo in my hometown this past weekend. I've been waiting for 3 years due to covid cancellations. I have to say that I was disappointed in nearly every system I listened to except for 2. One was valued around $400k and it absolutely rocked in every way. Gryphon, my God you make some equipment! The other was comprised of McIntosh and Sonus Faber, somewhere close to $80k and it was fantastic even though the speakers were lowly in the Sonus Faber range.

Thanks for the review. Nice details.

Probably the most honest review on these I've seen.. and it's really appreciated. I just received a pair of these today, got them for $449 on black Friday, so I feel pretty good about that purchase, even if they aren't perfect.. next year is wharfedale.. ;)

Good to see you, Danny, my Pedest'ale Tower speakers are sounding great.

Looking forward to seeing what you come up with Danny 👍🏾😎

Just bought these , cant wait for your upgrade kit!

Man u are like the speaker guru! I luv hearing your expertise 👍❤️

Can't wait to hear the sound clips, Danny. If what I hear from the speakers do sound better in The A - B comparison I will definitely be purchasing the kit. I'm not very tech savvy but I think I'll be able to figure it out. It'll be a fun little project that I can be proud of. Provided I don't blow the house up in the process 😂

I have hyperacusis and bad tinnitus.Any harshness in an audio signal is immediately apparent to me.Immediately apparent becomes discomfort after a short while.My friends that used to own an audio outlet used to use me as a "mine canary"with their systems.I could pick out anything that was not right very quickly.This is why i was looking at purchasing one of your single driver DIY speakers.They will not have the harshness of a tweeter system by default.And the parts you use will smooth them out even more.Thanks and take care Danny.

Great video. I am looking forward to the comparisons

Nice breakdown . Thanks Randy 👍🏻

Glad you are considering soundclips. They are obviously not able to give the *absolute* picture about a system, but as long as all else is being equal (the same music/tracks being played, microphone used, volume levels, room, etc.) and the listener uses reasonably good headphones, they do imho still offer the listener an idea about the character of a speaker, i.e. base, brightness, spatial imaging, resolution, etc., especially in A-B comparisons. jmo

awsome cant wait for the sound clips

Thought the sound clip was on this video dangit.. Rock on brother good video.

Looking forward to seeing this process unfold

Excited to hear the sound clips! Please, please, PLEASE have the clips synchronized and just transition from one setup to the other so we can more easily hear the differences. Do this and I guarantee people will hear the differences. If you just play one speaker set for a while, then play the other for a while, it won't be as obvious to those of us that don't have as trained ears as you.

I got some binding posts for $14 each for my home built speakers. Every part of the binding posts are brass, and plastic for the bases.

I'm really excited to hear the difference between klipsch and the XLR. I just bought a sale set of 600s and probably will purchase the upgrade kit depending on how they sound in my environment lol. But I'm as picky as you on frequency levels. You know back in the day most speaker companies focused on exactly what you do and installed them in good solid cabinets. Today they just fail to build a solid foundation. There units that are built right are just way too expensive to bother with.

Hi Danny I am happy you put the time and effort in to educate us in understanding laud speaker’s so we can get a good sound in your home.

I changed the signal capacitors in my Prima Luna prologue amp to a supposed expensive upgrade paper and oil caps. Although subtle they took away from separation in the mid frequencies but improved on the bass. I was about to sell the amp a year after that because of lack of interest in listening to music. I changed the capacitors back to the originals before selling and the life came back and two years later I still enjoy the sound and am not selling it. The point is the caps can make a subtle but very important difference to the enjoyment of listening

I purchased these speakers following the SG review and his passion left me really satisfied. It was a no-brainer purchase for me. If anything really positive can be said is that my hifi purchase have continued and taken me to some very surprising places. The dealer has become a friend and is going to open his own business. My research enabled me to obtain high efficiency loudspeakers, new turntable and experiment with vintage amps. I have since bought expensive second hand loudspeakers that I could never have afforded when new. I still have the RP-600M’s. Whatever faults you find they still remain a significant upgrade for many who had simply abandoned this industry altogether. Look out for a good second hand pair and enjoy! Well done Klipsch.

Danny you're the guy !!! Excellent video !!!

Excellent Vid. You are correct Sir, too many customers think they know it all & my 40+ years in the industry mean nothing.

Ever since Audiovox acquired Klipsch, profit over quality reigned supreme!

Great video on time 🙏

Hopefully you guys will use Ron's(New Record day)Binaural dummy head for the comparison.

Awesome technical analysis. Now i just need a recommendation for some budget home theater speakers

I'm looking forward to this, big-time.

Awesome Video man!!! Thank you for sharing!! I was wondering if you could do a Video on the Yamaha NS-10s monitors please! Are they only good for mixing or are they also good for enjoying music??? Thanks a lot!!! Cheers from Denver, CO.

Finally some A/B listening tests with upgrades. Seems it’s not only Klipsch that’s been doing some listening. Thanks GR!

Hi, after seeing a lot of you're video, I would like to see one with an old vintage speaker like the Celestion Ditton 44 or Celestion Ditton 44 series 2. I've got a pair of Ditton series 2 and I've alredy upgrade the crossover with good parts and I'm curious about how would you handle these ones .

With headphone mods I have done I have used modeling clay to add mass to the drivers and cups to help with the response and resonances. For the port resonances you mentioned, do you think adding mass with that method would help? Or would it just shift the resonance frequency?

Interesting. I have an older set of towers and yes the tweeters were always harsh, it's how I came upon them, a friend of mine couldn't deal with it..... I use them for av. But, I happened upon an AVI amp and it really brought the bottom end in line with the treble. Still not the best I've heard, but it is a factor.

I used Dans design to do a home built pair of open baffles and I love them. I dont think Id ever buy a pair of commercial speakers again.

Great info 👍

Yeah baby! Bring it... can't wait 😁

I'm intrigued. We've got the new Ref II speakers in our store now.

i hould love for you to do a pair of jamo s803. just because i have a pair and would to see where they stack up and what you would do to them. thanks for all the work you guys do have a great day.

I adore my Klipsch BUT I completely agree with you! The tweeter is 2-3db louder than the woofer and it sucks 😢 I do love the dynamics of my Klipsch R-51m and the off axis performance from the wave guide but Klipsch needs to replace the metal cone woofer with a stiff compliance paper coned woofer and focus more on the presentation of the midrange rather than the higher frequencies.

Just got my RP 6000 ii. Totally in love. I upgraded some 22 year old Bose speakers. Perfect for my smaller 16x16 room

I just spent six hours with my son listening to all kinds of music on his Gen 1 RP-600Ms. We had a great time; they sounded great. That’s not to say they sounded accurate, just great - without A/B, it would’ve been hard to tell. All I know is, they were really really fun.

Thanks Danny! Could you do the Polk R200 next?

This is my first view from you guys. Now subscribed. Do you guys sell a crossover upgrade for the 600M?

I enjoy the Klipsch boost on the high end. As someone who suffers from some hearing loss in that upper mid and treble area I find myself always adjusting the tone control or EQ up (if there is one). Flat response speakers are smooth sounding, but they always sound a little dull to me.

i.knew when Danny mentioned about opening the back of Sandy's golden ear amt tweeters he knew his shit.. I have audiovector s and the highs are awesome.. I trust his take much more the the people who review speakers who have been working at retail.stores or have no background in any engineering of any sort they are all late to the movie ...Erin is another good one for sure! not that there isn't good enough sound on the cheap today but I would not put my money on most of these men for the best sound for dollars...

Also coming late to the party, first of all, thanks a lot for these reviews. Even if I tend to disagree here and there, I still learn a lot, and that's what matters. Somebody may have asked this before - as it is an obvious question: why do you think Klipsch designed and sold a speaker with such notable dip at 1.5 kHz (first version)? I assume they were well aware of this fact, and I also assume that they have engineers how probably came up with a similar alternative filter design as you presented. Still, they ended with the "dipped" version. Do you think they presented different versions to some test-listeners, and maybe some thought that the dip in this frequency range actually sounded softer or more accommodating? I know that lowering the frequency in the 1-2 kHz range is not uncommon for that very reason.

Very good lecture, demonstration, and a thorough explanation of the new version of the Klipsch 600M; the 600M Version 2 loudspeakers. I'm glad I watched this video presentation about the new Klipsch 600M II Speakers. Thumbs up. I subscribed to your channel a month ago. I'm glad I did not buy that original version of the Klipsch 600M. Certainly most parts, and an alteration for another version can make a difference; and maybe make a vast improvement to the sound! Not much of an argument on what you have expressed, Randy. However, Steve Guttenberg communicated, and explained that this Klipsch - the original 600M was very good; maybe not excellent, but these large bookshelf speakers by Klipsch performed well, and were efficient! Here is an audiophile, and music fan who does not have anything to do with Snake Oil! Therefore, I do not completely understand, and coherently appreciate this discrepancy concerning the performance of these Klipsch speakers. Furthermore, maybe that Klipsch pair of speakers is a defective copy. Have you tried testing, and analyzing another pair of Klipsch 600Ms? As you know it's a process of the Scientific Method; anyhow, more analysis for absolute certainty. As you are well aware, and as almost everybody in this forum knows, Klipsch speakers have that reputation, and tonality of an assertive, energetic sound! That's the way these speaker manufacturers, designers, engineering department, management make these speakers. Correct me if I'm wrong, and very misguided! Then why aren't there plenty of music fans complaining, or remarking about the sound of music from Klipsch speakers that does not sound good, or have above than average performance? Isn't it a bit peculiar. Anyhow, maybe it was better that I did not buy the Klipsch 600M. Instead, over a year ago I purchased a pair of Klipsch 51Ms, and those book shelf speakers sound pretty good connected my second audio system; a harman kardon 490i Receiver 30W, high current. I also connected an Odd, used Rega Planar 3 Turntable whereby I installed a Linn Basik Plus tonearm with phono RCA cable, three longer hexagon machine screws, drive belt, motor suspension belt, and dust cover. Phono cartridge that I mounted is a new Audio Technica AT95E MM. Recently I've got to solder in a new capacitor. Sounds pretty good, and correct to me. Glad, and fortunate I'm a music fan, and audiophile second. 🔉🎵🎶

Nice work, maybe the best on KZfaq, parts matter %98, I had a high end Denon receiver and I was impressed, now I have a Sony ES receiver and I'm blown away by the sound quality, all because Sony ES uses much better Japanese parts 😮

Hi, do you advice to buy this speaker for hifi listening?

Great work as usual ! ;) But i am thinking why don't you build a diy speaker "à la klispch" with better drivers ? It would be a big step UP for those who like sensitive Horn speakers...

I have a pair of Klipsch rf25 floor speakers have you had those before?

As a suggestion please also do a test between the upgraded 600m 2 and the gr research speaker.

Would you recomend the RP-500M II or the RP-600M II as SL/R in a 7.2.4 setup? I already have the florrstanding Klipsch RP-6000F II and the Klipsch RP-404C II in the center.

If the units and the box are almost the same, you could just use the same filter that you did for the mk1?

Strange that the rp-600m speakers were so well received by reviewers when they came out, I have a pair of rp-160m that I rather like :) nice video as always

Have a question - You speak of theses Klipsch speakers as being "out of phase", how does that problem show up in the hearing of the speaker? What do I hear when speakers are out of phase? Can you clearify so I know what I'm listening for when it comes to speaker phase? Thanks.

Listen to what this man says people , no frills and no B.S! Love it 👏

It would be great to see GR-Research designing improvement kits for the Klipsch Heritage line; I just got a pair of Forte IVs and, to my ears,they sound great but I really cannot say anything about how they measure…

I just got my RP8000F II’s, I still don’t know what to make out of them. I got my Maggies LRS with GR-R xover as a backup just in case.

Hi, what do you think of the old Klipsch RP-160M? Given my budget I would like to buy them. Or, in the same price range, the Kef Q150, or other brands. You can give me an advice? I trust your judgement, you are very prepared. Thank you.

I think people want wonky speakers that only work well with certain recording balances. It's not like you didn't know. That said, having issues at @1Khz is not good/inexcusable.

My Elac UB5 always registers as out of phase by my Denon receiver but they still sound good.

I think I'll find a vintage good-looking console stereo, say an old Curtis Mathes system. Looks great in the family room and fun to listen to music again. Instead of listening to where the sound is, I'll just enjoy music and skip the measurements. Thanks

The horn in the version 2 is a full inch larger, don't know if you said that or not I didn't catch it, just information

Oddly enough, that system could do well with a second woofer wired in series. Add roughly 3db to the woofer output while evening out the impedance with the tweeter. And they could possibly back off the woofer's crossover point to eliminate some stored energy.

Hey Danny, just letting you know there is something up with your website if you weren't already aware. Links are not working, domain seems to be highjacked??

Since these type of Klipsch speakers are mass-produced and distributed, there may be a lucrative opportunity for someone to offer 3D printed crossover boards to go with these GR-Research upgrade kits. That would save a lot of time in these upgrades. When I upgraded my B&W CDM-1NT speakers, most of my time was spent on layout and and building the boards so that they would fit inside the enclosures.

Do you have any like objective testing or measurements that show the specific effects different parts, whether "higher or lower" quality parts do to the sound of the speaker. maybe you can quiet people saying that there is no effect by proving there is one

Did I miss part 2 of this ? Can’t find it

Nice T-shirt. Kramarić :)

hey, was trying to do some shopping the the GR websiet, but it says expired. whats up??

Danny, please consider hiring a recording engineer with a binaural Neumann KU 100 dummy head, GML preamps, and high end Lynx/Crane Song/RME/Prism converters to get a true binaural sound from the sweet spot in your listening room. With this, you’d greatly increase that 20% of differences to be heard on headphones. A listener on a nice but even low priced pair like the Status CB-1 would be able to get a much better feel for the differences than other speaker demo recording methods, which are often haphazard at best. Measurement mics in ORTF at the sweet spot can do a decent job, but for a serious listening endeavor, I’d recommend the above. Just this experienced audiophile recordist/mastering engineer’s 10 cents.

Thank you. The truth will set us free. I had the RP600M. BEFORE I saw your upgrade video. I found that they were too harsh for nearfield, and did in fact lose midrange/tweeter resolve due to that massive dip in the crossover point. Second: I have upgraded many speakers. Electrolytics in the signal path guarantee nothing more than mediocre sound and degradation in as little as 3 years. I use only metallized poly 1 or 5%. Just that change alone is very prominent in clarity. People don't realize how easy cheap electrolytic caps saturate- especially the tweeter. The 600MII has been hyped as the perfection of the sound, and the reviews strike me as exaggeration.

Hi from Germany, YT Snake Oil Audio mentioned your channel and he's completly right: You are making a real good job! Coming from PA I just start into the HiFi section as a hobby developer for speakers. My idea is to use an active crossover to develope the speaker. Do you have experiences with the difference in sound between active and passive crossovers doing the same job with the same speaker? Since I don't have any more records, the AD converter shouldn't be a problem.

What is another option with out a upgrade , a speaker already there for about the same price . To buy.

Danny I hope you give these new speakers a decent breaking in so it is a like for like comparison.

How much does "room correction" help or not with this? My Onkyo has a room correction program built in.

Why is the gr research website offline? I decided today was the day to buy the rp600 upgrade kits and suddenly I can’t find gr research on the web at all.

Waiting for the day when there is no more ferromagnetic material in components that are part of the amplified signal chain.

i have a pair of the rp 600 m's , first series,, how much do you charge to upgrade the cross overs and insulate them,, i'm not willing to do it,, but i'll pay you,, i need a website so i can get your address to ship them, quote me a price please,, thank-you

The box as you handle it seems so light ! It should have some WEIGHT...Where is the 1 inch MDF.

I understand better designed electronics may make graph more leanier (and sound charactersictics better depending on each one taste). But not clear how without changing the cabinet and especially the drivers, one can remove all its shortcomings. I find mostly it boils to one's taste... and each design has its strengths and weaknesses. But, inspite of so many requests, why don't you show the differences. In several channels, with proper headset we can surely hear the differences... But many thanks to your feedbacks which help manufacturers to improve their design/quality and stay competitive.

The video sounds better, did you change mics?

Love my Encores! Best thing i did! I Should re build the crossover now im better and the better parts.

Who is the Soccer Team on your T-Shirt Danny? Im a huge Glasgow Rangers fan myself : )

Bought a pair. Had them for a week and returned them. I kept staring at the tweeter while I was listening. In the box they went. Wanted to like them but oh well. I did hear what you did with Ron's pair and I could hear the difference. They were much cleaner 👍

Exactly, it really makes me shake my head when these people put sound tracks of two different speakers in the same system cause you can't actually hear the full difference without being in the actual room! And on top of that there is nothing else on the video except the music sound tracks!

Danny, the old school speakers that you were going to design? They are not a project anymore?

Will you review the 8000F Mark II model ?

With the old and new 600m both upgraded, are they close?

"Parts quality" definitely matters. I design and build guitar amps (tube and solid state) and also dabble in hifi speaker enclosures. Like most people, I started out using cheap components. And like most things in life, it's a compromise... price vs quality. I have made an A/B comparison with an amplifier where the only difference was the brand of the capacitors in the signal path. The difference was amazing.... I will say that higher price does not always mean better. There are plenty of diamonds in the rough out there. Also, there is a time and place for cheap parts. But in the end you have to decide what you will be the most happy with... With your ears and your wallet! Looking forward to watching some more videos. I just discovered this channel today!!

I was looking for you speak kits but link didn't work

Question The difference between REW and CLIO software?

Would be interesting to compare with Polk reserve R200.

Parts quality always matters. In everything.

Isn't klipsch the word for the sound of splashy cymbals? Of course they have to tune the tweeter higher than the woofer to live up to their name lol

I am waiting for you to respond to the Whafferdale Lintons and the KLH model Five with competeing designs by you.
