Bowers and Wilkins 685B Review

post #1 of 21
Thread Starter 
First off I'd like to say that I am pleased to make this my first post on AVS Forum, seeing that for a long time I have followed your venerated words of wisdom but never registered until now

So my current job at Best Buy as a home theater specialist has allowed me to become very personal with many mid-high end speakers. The reason I say mid-high end is because we all know that Magnolia does not carry venerated and awe-inspiring speakers such as KEF 201/2's, 800 series Diamonds and so on and so forth. But what the Magnolia center carries are speakers which have luxurious sound as well as a reasonable price tag.

I will be writing reviews for all 41 different makes of speakers we carry, but for now, I will be focusing my attention on the Bowers and Wilkins 685B Bookshelf speakers, as they are my favorite, and personal choice. These bookshelves cost a measly $650 a pair, and for that price tag suggest a somewhat meager performance. After all, directly next to them are the CM5's, which cost a staggering $1500 a pair.

After bringing a pair of these speakers home, I immediately removed the post-plates from the posts on the back, and bi-wired them to my Denon SRA297 Amplifier. Tweeters are wired to Channel A L/R, Midrange is wired to Channel B L/R. My wires are AudioQuest X2 Coecentric Twist/Time Corrrect LGC cables. Preamplifier is a vintage Onkyo P-3300, and source is an Asus G73 gaming laptop, audiocard set to 192k/24bit resolution (exclusive mode). Media player is Foobar2000 with resampler set to 192k.

I left the speakers to break in for a total of 29 hours playing sine wave sweeps while I was at work, so by the time I came home they would be ready for Stage 1 of critical listening. So upon arriving home on day 2, I decided to start them off easy with a rendition of "Feed The Birds"- Julie Andrews (FLAC 16 bit 48k). Though the encoding is quite good, it is a vintage recording so some audio imperfections are psychologically known, though seldom detected on entry level speakers. However, the 685B's immediately projected the claustrophobic characteristics of the microphone's used in the recordings, as well as the slight distortions that were present during the orchestral parts. But aside from those negatives on the recording's behalf, the soundstage immediately knocked my walls down (metaphorically) and the speakers showed off their extension and "airiness" upon hitting the crescendo. Already impressed with these bookshelf's ability, I quickly took a deep breath and forced myself to be critical and not partial. My next choice of song was "Elephants"- Rachael Yamagata. This song is known for having soft but present instrumentation, as well as very focused midrange frequencies that make most speakers fail by presenting them very exaggerated. However, the 685's kept a flat, dry timbre that was exceedingly pleasing to the ears. The tweeters did an amazing job of keeping high end notes crisp yet laid back, so to prevent any hissing or exaggeration of said frequencies. So at this point, there was no denying the very calm magic of these speakers, but I am one to always believe there is a catch. So it was time to give these speakers a run for the money. I quickly loaded up "Strawberry Fields"- Estiva, a fast paced House track which featured very deep synths, and a prominent driving beat. I said to myself "Ha, bookshelves will never be able to handle this!" To my intense surprise, the midranges hit VERY low for a diaphragm of it's size, but kept bass extremely tight and coherent. The high's were crisp and forward, but even the dynamic and deep synths that this song features failed to throw the B&W's off balance. So it was at this point that I gazed upon these bookshelves with a mixture of wariness and affection- I could not believe that a speaker of such diminutive size could have such a big sound. But now it was time for the ultimate test. I cued up my rendition of Tinashe- Zambezi (Accidental Powercut 3 Binaural), and decided to hear how well these speakers could handle the sharp, edgy reverberation of a xylophone, while still managing to present the long, extended roll off of the vibrating plates. I was absolutely floored by the way the 685's managed to reproduce the audio so flatly, yet dramatically. There was no effort on their part; in fact, it almost seemed to taunt me that I couldn't knock them down. Tinashe's voice seemed to fly with the clouds, the soundstaging was so wide that I kept looking left and right whenever the photographers took a picture in the background and the solenoids in the cameras clicked. By the time I finished my critical listening session, I was fully convinced that the 685B's were worth 4 times their weight in gold, for the sound that these little guys made was quite a wonderful one. Sure there are better speakers out there, but in my honest opinion, I don't think you'll find better for $650 a pair.

These speakers were picked as my personal favorites after spending over 300 hours demo'ing and auditioning Paradigm, Energy, Martin Logan and Vienna Acoustic bookshelf/wall speakers.

1 down... 40 more to go . Maybe there should be a separate thread dedicated to Best Buy speaker reviews as well.

Seriously, thanks for the write-up. It was a nice read. I heard the 685 once in a BB demo room and I was intrigued. I really like the way they look too.

Anytime I figured that most of us have to purchase speakers based on a relatively narrow spectrum and limited demo time, so some advice (though far from absolute) from someone who essentially is being paid to listen to speakers all day should be welcome

My next review is going to be the budget pair of Energy CB-10's, followed by the CM9GB's and CM5's

40 more... *sigh* it took me 32 days of living with the 685's before I was absolutely sure that what I wrote wasn't blasphemy or frenetic fan-boyism. Looks like I'm working overtime from now on lol.

Lmao tell me about it. I want to punch the writers in the face who write these damn product descriptions.

That made me feel very depressed when I saw that.

There were a few others, but that one stood out.

I have the B&W 602S3, the DM601 before that. The new 600 series are a step up, the 685 really is a wonderful speaker for the money.

Exactly- I found the 684's to be too lacking, but that is to be expected of such a small bookshelf, whereas the CM5's were a bit overpriced compared to sonic quality improvements over the 685's. I think that the 685's actually perform a bit better.

Lol- Summary is that the 685's are natural performers that hang with many speakers of a much higher price.

Hi DJ,

thanks for the write-up!

I'm currently listening to a pair of 685 + a HTM-61 CC (from a friend of mine who's building his HT room) and I'm enjoying'em quite a lot!

BTW, my front array setup comprises 3 X SVS - SCS-01 and I have to be honest though, the B&W's do sound better, mainly for music listening.

May I suggest, if you can, to put up a front array of the HTM-61 for testing purposes (all 3, vertically placed), as I truly believe these are a killer front array indeed, but haven't got the chance to listen to them this way though.

Nice review.

Have you also listened to the 686 which I think best buy sells for 480? How does that compare to the 685? Is the 685 definitely worth the roughly 150 difference?

Also were you using a sub with the 685's? It does not seem like you were but do you think they need one or are they fine on their own for music?

Thanks.

AVLiner, we do have only one HTM61 on display as a center and yes, it is an AMAZING center channel. I currently use it as part of a demo for the Monster Demo BD demonstration. I send people home floored by what they hear, so unfortunately I only have one instead of 3 for an array setup but even as one center alone it shines. Seriously tempted to buy two and make those my personal L/R channels lol.

Roark, the 686's are really intended in my opinion as rear speakers and/or height speakers. They are really for just complimenting a soundstage rather than being the main drivers. the 685's from B&W are the minimum main speakers one should get from this company, and they are worth alot more than the $150 price tag jump They sound rather lifeless and skinny compared to the 685's, but make rockin' rear channels.

As for the query regarding subwoofer use, I refrained from using a sub but because after conducting the test, I found that putting the foam plugs in the speakers gave them a bit more transparency, so I started using one. However the sub is so low that it only ever just adds a touch of punch on those sub 60k notes. So a sub is definitely recommended, however it is not necessary if only listening to music. If you listen to techno and/or heavy hitting music, then yes it is. But everything above 60kHz is just gravy with these guys.

That's why I asked... same feeling here, specially for those - like me - that prefer books rather than towers (size, space constraints, not so big HT room and so on......).

So House Music sounds great on the 685B? Cool! All I hear beind played through mid-high end speakers is jazz and obscure pop music. whats the diff between the 685 and the 685B?
post #16 of 21
Quite sure B stands for Black!

yeah the B stands for black thats all lol The 685's are killer on techno, and its largely part to that aluminum/nautilus tweeter combo that makes sine waves sounds so smexy
post #18 of 21
Can BB order other colors than black? If so, is there a price difference?

Nice write up!

I've been a 685 owner for about 18-mos now and I love them. The only issue I have is the lack of a proper listening room environment to really let them shine the way they did when I demo'd them at my local retailer. However, that's going to change in the next month or so after I get my proper 'man space' set up.

Thanks for the write up! Very informative.

I'm looking to purchase a set of speakers for HT system, I currently don't own any. I'm trying to decide between the 685 and the 3.1 Martin Logan motion series ( 15, 30 and 40). Any thoughts or advice?

Thanks.

Thanks for this review! I just bought a pair of these used on ebay for $405 and I am super stoked to make them the rear channel speakers for my in-process home theater build! I wanted these over the 686s because of the front port. My surrounds are going to be housed in columns and I didn't want the enclosure of the column to have as large an impact on the sound, so I really wanted to get speakers with a front-firing port. My mains are B&W 602.5S3 and the LCR60 center channel. While those are an older series, I'm still hoping that the 685s will pair with them pretty closely. Even though my theater isn't finished yet, I cannot wait to give these babies a try!!!
