XLR connector on 800 series subwoofer - not

[Mark-n-b]

I was wondering why the 800 series sub woofers do not have XLR inputs on the back, considering the XLR connecton method is supposed to be better than RCA connectors, especially over long runs.

Am I the only person to think this? I would like to see everyone's thoughts on this.

My pre-amp has 3 XLR sub woofer outputs, and it is a shame that I cannot use these to run 800 series subs.

I think it has something to do with the ground, but I really dont know!
They where about to put on the market the ASW 875 which has XLR and room correction but B&W consider that the room correction was not working as they want and abort the realise!
At least that was what my dealer told me!

[Mark-n-b]

Oh right, I thought I had seen somewhere in the past that a B&W 800 series sub did have XLR, now I know why.
I have sent B&W an email stating that this is something i would like to see in the future and they have said that they have forwarded my request to their product managers.
I find it strange that they would retract the ASW875 becasue they were not happy with it - i would have thought they would have worked on it until they were.

B&W continually works on product improvement. It could be they saw a better opportunity to build room correction features into their sister company's (Classe') front-end equipment instead. Other than providing another connecting option, the use of XLR's for sub frequencies will buy you nothing sonically.

... the use of XLR's for sub frequencies will buy you nothing sonically.

So, they are really any use at higher frequencies - so there is benefit from going from processor to power amp where the full range or higher frequencies are transfered, but do nothing for lower frequencies only?
I must admit that i do not know much about the connection, other than it is balanced and resists interference because of that fact.

[RebelMan]

XLR's are intended to suppress EMI and RFI for long cable runs. They also supply a lower noise floor of about 6dB which will manifest itself as higher voltage gain, i.e., more output from the volume control.

For the inaudible sub-bass frequencies of active subwoofers, you'll experience no sonic improvement with XLR connections. However, power amplifiers designed to drive passive loudspeakers that are able to produce a broad range of audible frequencies can benefit from the use of short run balanced connections.

For excessively long runs you are better off with BNC connections, not RCA and not XLR but those are rarely found on consumer equipment.

I never listen to inaudible sounds. :W

Yes you do. You just can't hear it. :rofl: :rofl: :rofl: :rofl: ;x(

Glenee said it! :B

[Mark-n-b]

Ok cheers for that.
I think I would still like to see the connector - after all my preamp has them and the ASW875 was going to have them. may as well make use of them even if there is only a chance if improving the sound.

Nope. To quote my wife: "I know you hear but you just don't listen." :nonod:

Are you sure? Clearly you paid enough attention to repeat what she said verbatim. Wives have a way of doing that you know, making you listen. :W

Maybe you should plug her into your subwoofer. :rofl:

If you do, be careful. Her bark could become worse than her bite. And that can not be attenuated.

But not to her. :T

BTW, I had the JL Audio f113 in the living room for about 6 months and she never noticed it. :W

I might call that a blessing. :B

When it finally came up, she said that she pays no attention to anything that happens in the 6 feet between the speaker plane and the front wall. Along with the f113, there are 5 monoblocs, 2 3channel amps, 2 line conditioners and some miscellany.
