#BowersWilkins #DM604S3 #Teardown
From B&W sheet: The imposing DM604 S3 is the only full 3-way system in
the range. The dedicated Kevlar® cone midrange driver is housed in its own isolated chamber within the cabinet and delivers all the nuances of the detail in the recording without the encumbrance of having to produce any bass.Twin 180mm (7 in) aluminium cone bass drivers combine with Flowport to deliver the deepest bass frequencies with ease. Like all the vented-box systems in the range, foam plugs are supplied to block the ports should the acoustic of the listening room impose too much bass
reinforcement. Suited to larger rooms, the DM604 S3 is capable of reproducing everything from the delicate sounds of a solo performance to the complexities of a large ensemble.
Specification of B&W DM604 S3:
- Frequency Response: 30Hz - 42kHz(-3dB); (-6dB).
- Power Handling (RMS): 200 W
- Recommended Amplifier Requirements (RMS): 25w - 150w
- Sensitivity (1W@1m): 90 dB
- Nominal Impedance: 8 Ohms (min 3ohm)
- External Dimensions: (HxWxD):994mm x236mm x398mm
- Weight (Individual): 29,2 Kg

Really nice video and presentation! :) Beautiful woofers, I love discovered voice coils.

[@anonymousmc7727]

I’ve realized I should just build my own…thanks

[@SahibBennett]

This line of the DM600S3 series is my absolute favorite. In sound AND looks. I have the DM603S3 and thr DM601S3. I bought them in 2005 and have been impressed for almost 20 years. But looking at this breakdown has taken some luster off of my "magic boxes". I still love them. But looking at the insides and the components makes me feel like I should try building my own. I still love them though. I might see if I can find a used quality DM604S3 just to compare.

[@N4CR5]

They all shared same drivers/etc so its same just larger. I've also had the 604S2 for over 15+ years, best investment I've made, out lasted multiple PCs and other equipment and can go up against anything new and similar price range in a stereo shop. Building your own is hard... easier to start with subs, less resonance/etc technicalities in design to learn.

[@divinginthedeep]

They look nice. But the woofers seemed somewhat misleading with those super wide dust-caps. I almost thought the voicecoil was going to be very wide in diameter.

[@janosnagy4382]

Electrolyt capacitors. Bravo B&W you saved 10 $ ...

[@spentron1]

53 and 150 uF caps are gonna electro, haha.

[@TheCornishGingerOfficial]

yes :)

[@dejandavkov]

Techscrew which one do you prefer 603 S3 or 604 S3 - i'm not talking about bass it is obvious that 604 has more bass.

[@larux100]

Finally!

[@N4CR5]

I have the S2. Beautiful to see quality inside on speaker design. You can get the dent out of the tweeter by gently pressing side of the dents.

[@Techscrews]

thanks for tip :)

[@Korisniknovi]

@@Techscrews Don't press sides of the tweeter, you'll only make things worse. Instead, use good-quality duct tape to get that out. Did that several times.

[@incomer012]

I've tried all sorts of ways. The best way is with hot glue and a cocktail straw

[@nicoastylehifiman]

i liked your video man, nice work , the chassis of the bass speakers is made of aluminum ?

[@Techscrews]

Yes, the chassis is made of metal.

[@pbsa1979]

This was not a very high model at the time, so material reflect this. I have few pairs of 604S2 and 605S2 and boxes are pretty much same. Money went into drivers, boxes are ok for price. Bit chunky, so happier in bigger rooms.

[@tottimejdi5820]

YOU CAN EASLY REPAir that tweeter. remove the dome with the three nuts and line it up with your fingers

[@Techscrews]

We know how to fix it, but too bad that there is a small hole in the center of if and it creates distortion, so we just replaced it

[@jiffiboy]

I have owned these speakers and the only gripe I had with them was that they need quite a large room as they can be bass heavy

[@N4CR5]

If you put them on spikes and away from wall/corner/etc the bass is clean. If you want even less port bass then stuff them and run sealed with a sealed 10" sub, they are clean and go down to 25Hz or better that way :) For very low yes you need a bigger room.

[@cosanostra101]

PLYWOOD? damn. My real wood tannoys kick ass.

[@mgm1411]

That's the most expensive "pillow" ever found, inside those speakers.

[@frankfarago2825]

It's not that B&W is any worse than Magnat Transpuls and all the others you had dissected, but it just goes to show that in the audiophile and Hi-Fi speaker racket, 90% of what you pay for is gimmicks, marketing hoopla, and vapor. All of them seem to eb building these things as inexpensively as possible. How much they end up costing -- that is where the "walking bullsh_t" part of the business equation becomes prevalent. Not picking on one single mfr -- they are all guilty as sin of doing this.

[@JasonLeaman]

Yup! Look at the crappy crossover's inside and the cheap crappy caps. particle board boxes :( Cheap cheap with over marketed technical gorgon !@

[@wilfredonacional1295]

The woofers looks like an ordinary speakers, the wood material used only cheap, the other brands of hi end speakers use hi quality real wood.

[@aapaap8595]

Lol, they weigh between 25 and 30kg each. Don't talk crap when you know nothing about them.

[@troybakker7628]

@@aapaap8595 but if you make a tower from 18mm mdf with the dimensions 100x30x30cm your enclosure already weighs 16kg and thats without any bracing or anything. So of manufacturers want to make a heavy speaker so it looks premium on the spec sheet they will just use mdf or more mdf then on their cheap speakers. Weight only says something about the enclosures not so much about the driver unless you know the driver weight

[@djlilbone]

This is the comment I’ve been looking for! I’ve always wondered why are most of these “named brand” speakers soooo expensive. I’ve seen sets that cost up to $250,000+. That’s ridiculous!

[@m1k4c]

If you really want your cat to help, you should disassemble stuff as soon as you bring them into your place. I don't know, man, I think B&W are just crazy expensive. Excellent speakers, ofc, how could they not be, but I think we both know ppl who can do the same job on half their budget.

They look well built, but personally I hate that they use plastics even in rather expensive speakers. Also metal domes NEED protection. This is just a strategy to keep people buying new speakers.
