Comparing Bowers & Wilkins PT.1

[@2idiot4u]

The 606 tweeter isn't mounted from the back side. The metal surrounding can be removed, then you will see that it is held in place by four small bolts.

[@adanbrown]

They are two different series I guess. 600, 700, 800 - while I do find it interesting it would have been better to compare the 705 S2 - that would have been a closer comparison in terms of how they have evolved their materials and other techniques.

[@kdomster9141]

Absolutely, it would have parts quality specially tweeter cap as good as Danny's fav Sonic Cap, Mundorf Brand that is in the same quality territory as SoniCap or better .... Danny did not mention that these woofers are top notch quality and build better than what Danny's uses in his design....

[@Justwantahover]

I got some 706s and use them for reference for my speaker building. They are my bass-med-treble level guide. Essential for an amateur like me with varying room acoustics. I copied the sound of the 706s with my made speakers, but then changed the sound on my made speakers just a little bit for my personal touch. I reckon my 706s lack treble a bit in my room and the voice sound is a bit warm and not throaty enough. Now, in that room my made speakers absolutely smoke the 706's. No bought speaker priced at 2 grand is going to sound exactly how you want it...but with making speakers from scratch with 2 grand monitors, you are going to make great speakers. That is if you know how to tweak the sound of your speakers to make them sound how you want them to sound (instead of a clone of the monitors). And if you can build crossovers you can change it if you move to another room (or if you change the room's acoustics, or even if you move your speakers).

[@IliyaOsnovikov]

Those speakers are from different price categories. 700-series speakers are always a couple of times more expensive than 600-series.

[@brs2c]

Exactly. Would have liked to have seen the older one compared to its modern day equivalent, the 705s2.

[@phelanator5784]

He obviously doesn't know the difference between a 6 series and a 7 series B&W. I guess that's why he calls himself GR Research go lightly on the research part.

[@Andre-qg8ln]

Really looking forward to part 2 . I do have the 705 . Had also several speakers in the past but love these B& W’s . Curious what can be done though

[@dimisirgo5934]

Nothing

[@robertevans2143]

I would like to see a review of some Totem speakers. I own the Totem Rainmakers and they are one of the best bookshelf speakers I have heard. Made in Canada. I am using them with an older Audiolab 8000A amplifier (when they were actually made in England) and a Marantz CD63 Special edition cd player. Thanks! I always enjoy your channel.

[@RayPaganJr]

My 705 speakers still sound great. I purchased the KEF LS50 Metas to replace them, but after six months, I hooked the 705s back. Sounds way better and plays louder.

[@MyIDIsNotAvailable]

Makes you think what a bullshit this hobby and their constant "improvements" are right? I have amp from 70s that I would not change for almost anything new.

[@howmit6361]

So, valid comments about comparing speakers from two different ranges. I would much rather see a comparison between equal models. The old 705 adjusted for inflation new would probably be twice as much as the new 606. BUT, what is interesting, is that used, the 705 can be had for what the new 606 S2 retails for. If you can find one that is. Apparently people liked them so much there are not a lot on the used market. This may support my confirmation bias that old high end will best new at the same price - 705s at around 1k, 606 S2 at 900. Without knowing anything about either, one would think that the 705 probably goes lower because of the bigger cabinet, and unless the crossover is botched, might have better vertical off axis response. The time alignment may be better as well.

[@knockoutfloors4848]

On the new Anniversary 6 series, you just pop the metal sorround off from around the tweeter unit. It is not glued, justheld on with some plastic tabs, very easy to pop off. Then it reveals 2 screws that are holding the tweeter unit in. Once the screws removed, tweeter pulls out, don't pull too far, as you have to disconnect the positive and negative slider cables from the back of tweeter unit.

[@JuanLega]

It's not an orange to oranges comparison. The old 705s should be compared to the new 705 S2. The 600 series is lower in class from the 700s and therefore the quality is lower. .

[@gregoryhardesty6522]

hello sir, love all your doing. Have you ever played around with white van speakers to see how good they can get?

[@dannyrichie9743]

I have measured a couple of different white van models. They were pretty bad and a little beyond fixing.

[@RennieAsh]

White van are usually too crappy. But sometimes we have "almost white van" budget models, that could be improved.

[@BanBiofuels]

I believe the new speaker cone material is *Endumax* from Teijin Aramid. "Endumax, an innovative and superior cone material with performance beyond woven composites, has only recently been introduced to the industry. This new material is initially being introduced in a couple of different forms - woven fabrics, a cross-ply sheet of two or more layers of unidirectional material, and short cut reinforcement fibers as for enhancing the performance of wet laid paper pulp cones. The material is light and stiff, with a high Young’s modulus and high damping." --- "The stiffness for a given cone weight and geometry is greater than polypropylene and quality paper cones. From a speaker designer’s perspective, it is possible for extremely wide cone body angles (shallow cone), smaller voice coil diameters, and/or smaller magnetic systems to achieve comparable or superior results to existing speaker cone solutions."

[@bergennorway]

Back in the days B&W was good quality and design. Company was sold I think, then got separate again. I liked them before, but can not think they make as good speakers as they did, compared to value for money. It will be nice to see all videoes, what is pros and cons about both speakers.

[@Dennis-zo9jo]

Its still good qaulity he is comparing cheaper serie 600 with the higher qaulity 700 serie its not good review

[@wokthetalk3079]

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

[@Mike81111]

So question is: Do these have typical dip in the upper midrange section like Bowers & Wilkins is know for. We will see in the following videos.

[@terbo2000]

Is that the BBC dip?

[@stefanweilhartner4415]

i have the B&W CDM1 which is similar but from the early 90's. i changed the parts from electrolytic caps to foil and changed the coil to a lower resistance one. now i have the problem of dying tweeters again because the ferrofluid inside starts to dry and the tweeters then stop to move and even the coil then burns out because it draws more current. the ferrofluid tweeters are crap. i have wonderful vifa ring tweeters with the kind of phase plug in the middle. they are phantastic but i need a new case now.

[@Ebergerud]

Wonder if the old ones were made in the UK? I think you have to go to the 800 series now to find an UK system.

[@acegolemi3818]

Yes indeed, the old 700 series, as well as the rest of their range back in those days were made in Worthing England , or at least so it said on the label/plate in the back . I used to have a surround package from the old 600 S3 , consisting of LCR 600S3 , DS 6S3 and ASW650. Even that 600 series as a starting point in B&W was all made in England. Different times no doubt. Yes, nowadays only their top offer 800 is made in England. Regards .

[@JMJM75257]

you need to check out the b&w 601s3s really great pick up on the used market. a good contender to upgrade crossover also! I personally have a pair with clarity cap csa on woofer and one csa and one cmr on the tweeter, along with mills resistors as upgrade using rutchos design to reduce that excessive b&w sparkle!

[@Justwantahover]

In my room, my 706s brass band sounds like wooden instruments instead of brass. My made speakers brass band sounds like brass instruments instead of wood. And the piano sound on my 706s is "blong blong". But the piano sound on my made speakers "gling gling". And the voice sound on the 706s is 2D and not "throaty" enough. The brass band and piano on my made speakers absolutely smokes the 706s. Either my room really sucks treble or the 706s lack treble. I use the 706s as monitors cos my room acoustics varies a lot in the bass. I copied the 706 sound best I could with my made speakers and they sounded at least as ordinarily as the 706s. Then I tweaked my made speakes just a little bit in the treble and now they smoke the 706s. But!...I couldn't possibly make speakers without good expensive monitors, and they are a game changer for my speaker building habit. They were the thing that really got me going (they improved my speaker building so much).

[@theoboeman]

Where is part 2 for this video?

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 !

[@dhosekowski1391]

I was hoping someone maybe could give me some advice. I have cdm1nt’s for fronts along with cdm cnt center for home theater 7.1, music and gaming. I need a new receiver to replace my yamaha rx-v673 because the sub out quit working and it never sounded that great with the speakers anyhow. Budget $3000 possibly a little more if needed. Thanks for any advice.

[@champipy]

On older 602 models you could reach inside the box with your hands, and twist the tweeter assembly 30 degrees and it came off. Almost like a "bayonet lock".

[@Justwantahover]

I can buy all brass binding posts for AU $14 each. When you pay over two grand for some speakers and they don't have all brass on the binding posts, it's a bit piss-poor.

[@dynodin81]

Two different speaker categories/price range?

[@MAudiophile]

I like this kind of videos but comparison with older 600 series speaker would be both more interesting and fair to be honest. Anyway hope to see that in the future, that would be something!

[@glennjones6574]

The older one was vastly more expensive

[@shanehamilton6773]

If that's a fact. Can you please tell me how I can find these newer vastly less expensive B&W's? I'd like the new vastly less expensive 800 series while you're looking. Ok, TY

[@MARVELOUDIO]

Where is the old B&W matrix cab reinforcement? Biggest speaker invention in history! (sort of ..) Two steps forward one step backwards?

[@stevenoconnor5693]

Very interesting

[@erikparent8176]

When these videos pop up on my phone I used to think, "Hey cool Danny has made another video! But after I saw him in his tank top a few videos ago, I just call him Muscles McGee! 💪💪🏋️‍♂️ I'll have to watch this later, I enjoy these videos! 😉🙂👍

[@keithkrieger7075]

2 words: mike boom.

[@JasonLeaman]

Good Video Danny.

[@Dennis-zo9jo]

you are comparing 600 serie with 700 serie 700 serie cost more than the 600 Compare 705 with the new 705

[@Psyphonyx_Life]

Not a fair comparison. Needs to be 700 series for both. ( im sure anyone could see this difference ) get a new 706 for comparison .. That would be more aligned.

[@Psyphonyx_Life]

Im actually shocked that Danny doesn't even look into the specs or details of what is involved .. The cone material is called "Continuum" .. because Kevlar is a trademarked material by another company.. so B&W designed their own more for sound performance* 800 D3 had it first , I believe.*

[@brs2c]

Not the 706. Should be the 705s2. Both tweeter on top 700 series bookshelves.

[@tothemax324]

@@brs2c Nope, the 706 S2 is baffle mount

[@dannyrichie9743]

@@Psyphonyx_Life I don't really care what the published specs are or what they call everything. Half the time what is published and what is real are quite different. And those cones are made in China. I know of one of the companies that used to make them. There was a time that those cones could be bought for pennies.

[@brs2c]

@@tothemax324 I know. Carefully re-read what I originally typed.

[@hugobloemers4425]

Interesting to see how little these speakers change. The newer one is basically a cost reduction model (Made in china I guess) but to be fair, they do pass the savings to some unknown extend to the consumer.

[@HansDelbruck53]

extent, not extend.

[@jakobstephansen1826]

GR are wrong when it comes to changing the tweeter, and a lot of other things :)

[@kiettrinh8704]

Older one nicer

[@Bigirondoug]

Cheaper build is the result of the Canadian firm buying B&W.

[@googoo-gjoob]

shame. only solace, it isnt chinese, yet.

eum youre totally wrong.... b&w bought Rotel and Classé Audio and it has been sold to Sound United
