Just remember guys Danny is running a business, he isn't an impartial speaker reviewer, I'm not saying he is a bad person, or that he is misleading you, I don't believe that he is, but he does believe speakers should sound, and measure a particular way, remember that's what your buying into, his audio philosophy, as long as you know that. Personally I think if you buy this kit your speaker isn't a B&W speaker anymore, you've converted it into something else, a 'Danny speaker' I guess, just remember to trust your ears first and foremost when auditioning a speaker, and the key word there is 'auditioning', no amount of measurement graphs is going to tell you whether you like it or not, only your ears can do that, and also don't forget that your room will have the biggest effect on your speakers sound, people really underestimate this, audition, audition, audition, get it right first time, and trust yourself, if you like it that's all that matters, then you won't need to fantasy about tearing your speaker apart to 'fix' it.

Absolutely awesome work! Thanks for sharing these projects this is very interesting stuff! Subbed!

Sounds like B&W needs to clean house. A thousand dollars is nothing to sneeze at for many of us. Appears like their concentrating on their high end more. They get more word of mouth on the more affordable lines. Great job really enjoyed seeing the proof of what many were saying. From what I understand 1st order isn't easy to pull off and it's not for everyone.

Thanks so much - even with my basic understanding of acoustics, I appreciate the timing issues etc. I was about to purchase a very good condition pair of used ones.

HAYY ERRBODEE! Love it! Always get excited to see the charts before and after! Anyone else get that too?

Tweeter is easy to remove 😂🤦🏻‍♂️, The grille itself is just held on by magnetic force. You can easily lift it out of place. (One single edge of the grill has a little tab) Also, the laser etched metal circle just pops off after the grill is removed. A little force needed and it will pop of, exposing the screws for tweeter.

Superbly done! I wish that there was more reporting, like yours, on real product quality. Subjective reviews are obviously NOT enough. Keep up the good work and thank you.

Many thanks for the review and lab report on this speaker. I was about to get the other model up 706S2 but having research in YT, there were alot of mixed reviews on these B&Ws. many reviewers rave about this speakers even getting awards but I was skeptical and fortunately waited for the proper review as you did here, rally appreciate your work. Cheers.

Don't follow reviews, listen yourself.

i got my 606 s2 before the price increase for 600 at ABT and for the price they are AMAZING. I have the 705 s2s as well and for the money id recommend the 606s2s allll day

Now remember that you listen more to reflections from a speaker than onaxis. The average of the before measurements is ok horizontally. The tweeter is removed from the front by removing the grille, it loosens easily at the bottom first. Then remove the decoration ring as on the bass unit. The tweeter can now be removed by loosening the four machine screws. Remember that you can always ask an authorized dealer if you are in doubt about something another time. (Google translate)

Hi Danny, Thanks for settling this once and for all. Those who appear satisfied with this speaker have had to do some serious shifting around their rooms. Most seem to have had their rooms aucusticslly customised. I think the manufacture has shortchanged the customers with this speaker based on all the reviews I've seen and heard.

Danny I can really understand and appreciate your knowledge and your talent. All those 100 hours into thousands of knowing what each part will do and applying them as always thank you for sharing. I just wish main manufacturers we'll have a really decent entry-level speaker to show showcase the rest. can we have a sound demo before and after then again this is your Channel and you can run it anyway how you feel fit too Ride Easy

Hey, Danny, loving the Pedest'ale Tower speakers.

Thanks very much Danny, I have a pair of 684 and the treble is terrible lol I have a hearing loss that starts at about 5500 hz (tinnitus) and your saying there is a big drop in the speakers response in that area, no wonders the BW are not a good match for me. I'm in a lot of facebook groups and just recently I came across 3 peoples who want to build super tweeters for their BW , looks like redesigning the tweeter would be a much better option. Thanks so much for explaining this.

There are many days I wish I had my own beauty ring.

Well done, Danny! Have you had time to check your speaker wire with the Aegir amp?

It would be neat if you could analyze some of the classic speakers from the 1970s such as the AR-3a, The Large Advent speaker, the JBL L100, The old KLH speakers, Rectilinear III, among others. I realize that these are probably not ones that you would make new crossovers for, but if you could confirm these speakers are performing like new, it would be interesting how the crossovers operate on them.

You could show it's not stressful on the tweeter by showing distortion levels of the final product and compare it with the before.

I’m loving the sound of these paired with a marantz cinema 50. I get no harshness upper frequencies at all? My hearing is pretty damn good.

You are a great educator Garry. Thank you.

I’m thinking of buying some B & W 603 S2 AEs, going to be giving these guys a call😌👌

B&W may or may not be aware but that ”little bit of a proud area” might be the real reason they went for a lower electrical slope higher up in frequency instead of a steeper filter lower down. This mod might be tuned to a very well treated room, not emphasize as much of the wide dispersion and hot power response of the tweeter at lower frequencies.

Danny have you tried a head mounted microphone? Convenient and good tone without it getting in the way.

I've heard all b&w speakers have Van Den Hul wires inside. That would explain Danny's finding

I realise that they are not B&W speakers anymore, but Danny is a means to get way more expensive sounding speakers, from cheap speakers. It seems that speaker manufacturers make the cheaper ones sound bad intentionally. The Nautilus demo on YT sounds heaps better than my B&W 706 speakers. My speakers are a bit foofy in the voice sound, not throaty enough! Yet the Nautilus have heaps of timbre in the voice sound. Nice and throaty, just how I like it. 😅

B&W had that colored sound that is alleged to enhance or be better for vocal range. Flat is not good due to room differences. But audio is really not measured but enjoyed musically as surely measurements we HV are sorely lacking psychoaciustically. Case in point ate tubes which measure abysmally but sounds so much more realistic that any good recording uses it from it's source to the recording. Our ears are the most advanced acoustic tool we have, let's use that more. Only you have to train it by listening to actual instruments live.

I really like to see some German classic speakers, Canton,Heco,Quadral,Magnat. Specially Canton.

B&w 600 series used to be so easy to buy and replace parts. The tweeter used to be a simple twist to unlock.

So with a simple 1st order tweeter cap reversing phase by 180° is that why i have found inside some simple crossovered speakers with the tweeter wired in reverse ?...positive x-over cable to negative tweeter tag & negative x-over cable to positive tweeter tag.....

I'm buying these speakers later in the week and will send them to Rick to get pimped-out! Thanks bru!

I’m glad I got 606 S1 as I hear so many issues with the S2 model / anniversary edition. Meanwhile I use 606s1 as rear speakers now.

Danny, I've watched a bunch of these upgrade videos and have learned a lot, but my question is this - when you give the price for upgrades at the end of the video, is that per SPEAKER, or is it per PAIR of speakers? I know which one I hope... lol. Just clarifying.

I generally do not write comments on KZfaq. This video made me do it. I have the B&W 606, 607, 603, HTM6 and M-1 Speakers. These speakers are simply amazing. All these measurements are simply pointless in the ears of the listener. I have 606 in my stereo listening room paired with a spectacular Denon stereo amp and an SVS subwoofer. The 606 is simply spectacular. Best musical speaker I have ever heard and I am an audiophile. Forget the mixed reviews, forget all the measurements; B&W 606 are simply awesome and amazingly fast and musical. Period

I have watched a number of your video clips and am always surprised at the level of cheap parts used regardless of what the retail price point is, 500 bucks a pair or 15K a pair.

I was told the B&W 606 was an excellent speaker, but now I'm not so sure. I started to question other purchases and now am questioning the nature of reality itself.

When applying a bit of trial and error with a custom cross-over is there any reason you can't use cheap components like electrolitic caps and iron core inductors to get the values correct, then substitute in good components of the same value? Having a stockpile of sonicaps and erse indusctors when starting out is a bit pricey

7:08 love this channel. this guy has no filter, love it. but, seeing him wipe his nose all the time and then touch the client's speaker. i am getting freaked out watching. 7:32 and picking his ear and then touch the client's speaker.

My Triangles are waiting for you, Danny.

Danny, are first order crossovers suitable for D'Appolito (MTM) driver configuration (in case when both driver types have a lot of range extention beyound crossover point) or the third order would still be better?

Interesting, 1st order x-over at this price level, less expensive design but trying to achieve better phase or group delay? Fewer components in the circuit? I used 3rd order back around 1980 when I wasn't tri-amping.

"One thing Linkwitz said stuck with me. I'd asked him about measurements, and the often considerable difference between what's seen in measurements and what's actually heard in listening. 'What is important to the eye is not necessarily important to the ear,' he said. 'Why should it be? Nature makes sure each does its job and does its job perfectly. You get cues from the eye, but some things that look gross in the frequency response, the ear says, "I don't care".' "That from a guy who's more a scientist than an artist. Never forget those words when you look at measurements,

Has anyone here done this mod ? It's a big change going from 1st to 2nd order. Would love it if an actual customer talked before and after. In particular, does speaker lose its detailed clarity and transparency that b&w known for?

Why does the-manufacturer do what you just did before releasing it? I think it’s a legitimate question!

One question, if I have electrolytic 4nf(micro farad) in tweeter crossover in series with tweeter, and replace with mkt/mkp 4.7nf(because i dont have 4nf) is there would be a problem in sound,phase shift,or something? Crossover contains one ferite/laminate core inductor 0.32mh on mid bass and 4nf on tweeter . This is satellite speakers, sub is class D powered

It would really help if you recorded a before and after video for some of these upgrades. Lounge and rock song would be good... or some orchestra piece. If you have an chamber of some sort to take measurements... record song while there.

Would you reccomend this kit for the regular 606's? I know they changed the crossover for the S2, but I'd assume they used the same design, different filters?

Whith a 10 degree TOW OUT, Would the reflection off the wall make the sound muddy?

I got 5.1 system 606 B&W on the front 607 B&W at rear the center B&W HTM-62 the Subwoofer is Klipsch the Amp Sony STR-DH770 and the sound of all this is Amazing, you can fix the sound in the EQ settings in the AMP. I would not change anything to my speakers because if i change something to my B&W They would not be B&W Anymore , i trust more in my ears than on the science in this case, but, Mr Dany should Build their own Brand, it would be interesting, of course count me as a customer, I am sound lover.

Paul McGowan HATES the B&W tweeter. He's got a fair amount of bona fides in the audio world.

Is this upgrade kit also suitable for the original B&W 606, not S2, logically it should as crossover reportedly was the only difference between these models?

You remind me of a Doctor lol . " Well ma'am/sir ---- sighs -- you're not gone like this . Your bmi is scary , thyroid not looking it's best , rbc is like of Dracula and estradiol is astronomical ,but I have a fix for this ... SoniCap "

Man I would like this kind of kit for CM7 that would have been awesome!!

If I was to add a 2ohm resistor across the tweeter terminals would that tame the high end?

them speakers aint too bad.

I have seen both bad and good reviews on those speakers,I have never heard them, but I have own plenty of b&w and They have never disapoint. Right now i have the 702 s2 and i think They are incrediable sounding speakers,

My money says the encores would smoke em in about every way. I do love the look of the 606 though.

I've got a pair of these and one of the woofers has just stopped working. Anyone got any tips for how to remove?

How far the mic is when you take these measurments and what high (leveled at the tweeter, in the middle of the MB and TW or...)?

I saw a review of the signature series of this speaker not long ago and the YT reviewer thought it was a mess. After your review, I know why. It was out of phase at certain frequencies.

What is better, closely matched quality drivers or crossover parts quality?

Andrew Robinson was Right. Damn!!!!!

Take the port out to gain access to the tweeter nuts

When you compare these to the way Epos build their speakers it's like chalk and cheese. The Matrix series was good, i thought the 1600 was very neutral, but some of their latest offerings are built like budget Ikea furniture. I think they've worked out that yellow drivers and grey roll surrounds have a hypnotic effect on potential buyers.

I have these speakers and note that the plastic port and post component can be unscrewed and removed. Was it not possible to do this to get at the tweeter?

Are there ANY speakers that you like without a teardown and rebuild? I don’t like the idea of buying new speakers just to tear them apart and rebuild them. It may be fun for you, but there are those of us who’d rather not do that.

Can anyone tell me if can I change myself the crossover? How hard is it?

Is the kit for both speakers, or do you have to buy 2 kits?

I think that bump is B&W's signature sound, if we change it to flat response, will it not be a B&W anymore?

I hadn't been a fan of teardowns that reveal cheap parts, but ones that make little or no audible difference to an audiophile, but I think the whole 600 line *IS* cheesy, in many ways. The corners B&W had cut to meet the line's price point, were evident. I had gone with Monitor Audio's Silver line instead, years ago, instead of the 683. MA Silvers are built better for under $2000 (but not always providing better sound than some others). I hadn't liked the 2.5 way woofer problems with the Silver 6. 2600 Hz crossover point was too high and I wished I had gone for the more expensive 3 way.

You look at some more down to Earth brands like Wharfedale which pound for pund beat these posers at less than 1/2 the price and realise we're been taken for a ride. People will buy anything these days that's been over-popularised by online reviews and social media posts created by the hype followers.

Try to rotate tweeter from behind?

Hey Danny. Thanks for another critical review. You had mentioned the tweeter mesh grill. How was the frequency response without it?

You very rarely get to see what goes into a speakers workings. I was watching via subtitles I realised these are not B M W's as it stated as those boxes have no wheels.

I don't know what it is about B&W speakers but they just don't do it for me. Heard some 804d's years ago and the salesman was raving about how great they were. I was thinking to myself are we listening to the same speakers? From memory they were connected to some McIntosh gear.

Aren't you worried about that rise in the 6-8khz range where most sibilance occurs? I'm real sensitive to it personally, I can take a hot mid range better than the place where the esses live. I much prefer AMT or planar tweeters, but they too can make my ears bleed with Sssssss. It's not a P or a T for me, but those esses will kill me every time. Anyway, I really like these videos showing the measurements, good stuff man. Cheers 🍻.

I would love to hear B&Ws engineers rebuttal to this video.

Honestly, i Don't know How the reviewers test an Speaker, The way i do is, the first step i drink a full cup of coffee, next i put my amp on pure Direct, the speakers settings on Large (full range) turn off the Sub, and i start to listen 3 ft away in front of the speakers, i do this test after 50 hours to play the speakers, as the factories usually recommends, and works for me.

Haven’t heard a B&w that had any bass yet. I only listened up to the 702-signature. I’m sure eventually they will have some bass, but I gave up.

Video Request: can you please do a video explaining why these giant hifi companies dont do this from the beginning. im fine with the cheap cost cutting. but stuff like phase irregularities and bad driver choices that have weird ringing and band-aids to fix them. these mega companies have to have the best measurement equipment in the world including anechoic chambers. how do they get away with this level of product?

Hello Danny, Have you come across a pair of B&W DM7 Mk1 (the original version). I would like to add tube connectors to my pair, upgrade the crossover and remove the two fuses to tha pathways as well. I also like the feet that are on the bottom of the pedestal base. I look forward to your response.

I have seen some of the reviews about this speaker and the more negative reviews match the conclusions here. With that, this is almost a text book case for the hypostasis that you can replace listening with measuring. I am not taking a side here, just making an observation.

It constantly surprises me that these big brand name speaker companies must not even run similar tests on their speakers before producing them. Do people not hear these issues? Danny makes this so clear that these “quality” speakers have significant issues. Thank God for Danny being able to offer corrective crossovers to fix these “quality” speakers.

Just a small bit of criticism no insult or harm intended. I have watched IDK 40% of your video's. When you start talking about the test and show the graphs and talk about them its as if you were talking into a mirror or another sound engineer and they understand every thing you just said. I have tried to understand the graphs and what I am looking at or its like your taking to a classroom that has already went thru the first trimester of learning the ABC'S. I am a 42 year Boat Bike ATV powersports mechanic and last 12 shop owner and sometimes I have to dumb it down when explaining to my customers. To grow your channel lots of people need to understand what the heck your talking about because I would say like your customers 90% of youtube watchers love music and HT but not to tech savvy on the scientific part of it. Remember most of us you will need to explain like you would to a child just learning. a pencil or pointer while showing the graphs would be a great help.

I’m somewhat curious as to why audiophiles don’t just simply use professional studio monitors to listen to music. A good amplified monitor from Neumann, Genelec, ATC or other can beat any audiophile speaker when it comes to a flat frequency response. If a flat frequency response isn’t desirable for hifi, then, could they not just use some sort of equalizer to dial it in as they like? It’s just a question that I’ve been curious about.

I just got a pair and I suspected they were boosting somewhere in the upper mids and treble range, its a really shrill, fingers down a blackboard kind of sound. On certain recordings it sounds like it's clipping. Particularly bad with vinyl or vinyl DJ mixes, it's in the frequency range that blows up any surface noise and causes bad sibilance on vocals and snares, it's really not very nice. Only had them for 2 days but I can't live with this. Some stuff sounds really good, I appreciate why people like them but anything in that frequency range to me just sounds nasty, I need something more accurate. Great to hear that my ears weren't deceiving me, those are considerable boosts between 4-10k

Hi GR-Research May we know ? Any Great Low Base 100uf Cap on market is very good for Low base Speaker use ! Can u recommend ! Pls advise can. Any 100uf Copper Foil cap u can recommend !

I like my 606 2s a lot. They work fine with my old Sherwood receiver - high sensitivity helps there. I listen to classical 100% and the quality of the CDs is pretty high. My room is a good one - lots of soft stuff and a good size for the BWs. It would be fun to have GR fix my speakers up - if nothing else, I could see if my aging ears would be able to pick up the fine points. I'd like to try a GR DIY speaker system too. But guys....this site is not about to find a speaker that can't be improved with a little money sent to GR. I'm not throwing stones or doubting in anyway the skill & integrity coming from this site. But I am pointing out that in the real world there aren't a boatload of listeners that are going rip their speakers to shreds and put them back together with new parts. So I'll have to live with all of the weaknesses that I really don't notice and enjoy the music - and I won't need any repairs to do that.

Sir which is perfect speaker according to your analysis and research?

That tweeter doesn't twist out like older models?

The front panels are made of plastic or mdf ??

i got this speaker...and it plays superb...especialy on real good gear. it play well beyond its pricetag. more like 1500€ speaker. so i realy get the hype and dont understand the down hype. imthis speaker never fatuiges the ears...it plays realistig with enough details to call it hohh end. the bass is also not lagging...yeah its more om the warm side of the sound but it fits pretty well. thats why this speaker makes that much fun. it play inatruments real plastic in the room. the treble got air in it and the right amoubt of dynamics...overall its a real good speaker. the 706s2 can get fatuiqin but not the 606s2! use a amp for 1500€ and a good akm dac for at least 1000€ just to get 90% of the speaker. but i also only use nordost cables and accuphase pre and power amp😅. so my gear is way zo high for this speaker...but its brings rhe speaker to the max...🤣 i never use those cheap binding connectors....thats always a nogo for every speaker.

I sure wish I was knowlegable enough & my hearing good enough to know why I shouldn,t like what I do like about the speakers that I like

I have a relatively modest budget and I am not what you'd call an audiophile....meaning I didn't understand more than half of what you said. I just know that I like what I hear. Is there a speaker you like that doesn't cost $10K?

The bump of woofer amplitude around 1kHz when tweeter is off is likely to be an artifact of crossover circuit with the tweeter cut off. The tweeter acoustic level is -15dB down around that frequency. No matter what the phase relationship is, the acoustic output of the tweeter cannot acoustically tone down the woofer by as much as 2 dB.

Could you have a look at the 705 s2 ? The newer model?

I like to hear his opinion on harbeth speaker.

Guess sometimes we forget we listen with our ears not our eyes. Maybe that's why many good measuring solid state Amps before sounded crappy and why tubes / analog are always used in the recording chain and playback of ultra high end systems and recording studios. I'm saddened by those who listen more with their eyes and aesthetics because it hampers development of truly great sounding systems.

Great video. I am always amazed at how poorly designed speakers are from even high end names. What were they thinking with that crossover design? They could have spent $150 more and made those things so much better and recoup the money

Hello guys. Could anyone recommend a decent pair of bookshelfs for around $1000? THANKS
