A couple of comments were made about the size of my listening room, in terms of the space being large enough for 801s. Certainly, the latest version of the Bowers & Wilkins flagship will work well in a much large space than mine. But many audiophiles with a more typical domestic listening environment will want to know if the speaker's a consideration. I've formally reviewed about 30 loudspeakers in this room (and have tried out a few others) and I have a pretty good idea of what will work at this point; so does Robert Harley, who assigns 90% of the products I review. Manufacturers generally do their "due diligence" to assure that they aren't setting a product up for a negative assessment by arranging for it to be heard in an inappropriate setting. So, I can assure you that there's been an informed decision made about bringing a given big loudspeaker to my room.

Nominally, my listening room is 15' x 15', which doesn't sound promising for a larger speaker—but all 15' x 15' rooms aren't created equal. Here's my view of why mine worked out well with the 801 D4s.

• The ceiling is high, and it varies in height, from 10' to 11'6".

• There's a 9' long hallway leading off from one side, even with the right front loudspeaker, as well as other asymmetries/irregularities to the room dimensions. I've positioned GIK diffusers in the middle of the front wall. I usually measure the in-room frequency for each visiting loudspeaker with a Dayton OmniMic system and there haven't been disqualifying room problems—significant modes, etc. I use that information to most effectively dial in a subwoofer, if one's to be used.

• I enjoy relatively near-field listening. I played in orchestras (and rock bands) when I was young, and this audio perspective gives me some of that participatory sense.

Obviously, there's a limit in terms of how large a speaker can go into my room, and I've turned down projects based on my understand of those limits. Clearly, Wilson XVX's or Von Schweikert Ultra 9s don't belong here. But, especially given the specifics of my 15' x 15' room and my listening practices, I feel that the new B&Ws were not mismatched to my space, and that other interested audiophiles with a similar situation should be dissuaded from investigating further. After all, I'd say my review was a positive one.

Thanks for hearing me out. And if anyone's ever in Philly and wants to hear the room (with my usual speakers, Magico M1s) drop me a note and we'll find a time!

Hi Andrew, welcome, I guess you mean Magico S1's instead of M1's ?

Thanks for taking your time to respond on this forum which is greatly appreciated.

I am curious how far your seating position was from the speakers? You mentioned in your review you were only 8 to 9 feet away. I read that B&W claims you should be at least 9 foot 10 inches away for optimal integration between the drivers for best sound and would appreciate your comments on this. You mentioned that you like to listen in the near field and you found yourself “leaning in to fully engage with the music”. I am wondering if this is due to your seating distance from the speakers?

Can you also comment on how much tow in you used and if you tilted the speakers forward based on the tweeter height in relation to your ears at your seating position?

From my experience all of these parameters considerably changes the sound at my listening position with my 802 D3’s in house.

Default More on 801 D4 placement in a small-ish room.

Sad to say that the 801 D4s are just a fond memory. But my best recollection is that my ears were 8.5" from the front plane of the front plane of the speakers.

When I angle loudspeakers in toward the listening position to achieve the best imaging, I work with a friend using a white noise track on endless repeat. We keep changing the angle until there's a discreet "blob" of sound located centrally and when one moves his head from side to side, there's an imaginary boundary crossed where the character of the noise changes. This tedious exercise does seem to correspond to the most continuous and specific imaging when music is played. A good point to start the process, we've found, is having the speakers aimed in a way so that imaginary lines from the middle of the tweeter cross just in front of the listener's head.

I do attempt to adjust a speaker's spikes not just for leveling but to be sure that, as much as possible, the tweeter are aimed at ear level. I'm certain all of you do as well.

The "leaning in" was my clue that I needed a more robust amplifier to get the 801s to sound their considerable best. My experience was the same with my Berning Quadrature Z monoblocks that are rated at 200 wpc. (Although all 200 wpc amps aren't created equal, of course.) It was only when I borrowed the Tidal integrated that the sound was as authoritative, and the bass was fully controlled. (The room frequency sweeps were quite different with the Pass XO 80.6s and the TIDAL Intra, with some messiness in the lower octaves nearly completely eliminated.) This isn't the first speaker I've had this problem with and, as a result, I just sold the Bernings and have a pair of TIDAL Ferios coming in a month or so. They ought to handle just about anything.

My main speakers are neither Magico M1s (which don't exist) or S1s (which I have for rear speakers when I listen to m-c music. They're M2s.. Sorry about that.

Thanks for clarifying, Andrew. I did not comment before, but I was confused because I could not quite believe that Absolute Sound would have reviewed a pair of speakers in an inappropriate room. Cheers

Hello Andrew and very glad to have you on AA. I read your comprehensive review and thought it was informative, well written, and honest. After reading it and thinking about it, the conclusion I came to was that it had to be your room, since the speaker is rated at 8 ohms and goes down to 15 Hz. It should not need a subwoofer. It should be relatively easy to drive. The roll off beginning at 38 Hz was perplexing as was the change in the frequency response with the various amps. When I am evaluating a speaker for purchase, I want to know how it sounds without a sub. It's unusual for speaker like this to require a sub. I do not believe the speaker worked well in your room. Just my opinion.

Best

Charles

Default 801 D4 powered by Denon AVR X8500H

Hi,

The 801 D4 are on it's way. Can they be powered by the Denon AVR X8500H?
Thank you kindly.

Cheers
Caesar

Caesarius, welcome to AA. Huge congrats on your 801D4s! They are tremendous speakers and worthy of a flagship designation.

Although the Denon AVR X8500H has all the bells and whistles, its power may not fully maximize all the performance you’ve paid for in the 801s. In my opinion, the 801s will definitely benefit from gobs of power. If you have or are considering the Denon AVR, I’d suspect you have other configurations in mind.

Lots of friendly, experienced, and expert AAs here so I’m sure they will chime in.
