B&W ASW675 turn off noise...

[SimonO]

My ASW675 has developed a turn off thump... I have spoken to B&W technical support who have said that this is a normal characteristic... I'd be interested to hear from other ASW675 owners if this is the case or not...

Just ckecked, and mine does do this, but you have to listen very carefully for it as it's barely noticeable.

Although I'll probably hear it all the time now

Gain is set around 12 o'clock on mine, with the amp on -3db

Hi Simon
Does the sub only thump when you turn it off manually with the on off switch as this is the only time it should thump.
Why do you turn it off though i left mine in auto for 6 months until i sold it,With no problems.

Thanks guys... I should have been clearer, the amp is set to auto and it turns off after a period of inactivity e.g. a quite passage in a film... It thumps and then you hear the relay click, I'm probably sitting 5' away from the sub and it's clearly audible... I'm 99% certain that it hasn't always done this, as I would have noticed it straight away...

Hi Simon
Your correct that it didnt thump when going in to standby mine never did all you ever heard was the click so it does seem theres a problem.
Does the sub thump when changing over inputs on the amp say dvd to cd or is it only when the sub goes in to standby.
Cheers Gonzo.

Thanks Gonzo... No, it's only when it goes into standby... I haven't really looked at it properly yet, I'll try manually turning it off and also try it with the input disconnected and see what happens...

PS I'm looking at the M&K 850's, how do you find them..? I wouldn't be able to hide an SVS sub from the wife unfortunately, but for the size, the ASW675 is very good...

Hi Simon
Make sure everything is turned off when pulling any phonos out.
The m&k 850s are superb with movies very detailed you can hear a pin drop there that good also very dynamic they never seem strained but they do need good amplification to make the most of them.Music is slightly dry but at the end of the day they were meant for cinema its not that they sound bad with music they could sound better at £500 a piece.
PS the asw675 is a very good sub i cant fault the performance you get from such a small enclosure.Btw the svs only takes up the same floor space as the asw 675 but it is a bit taller and a bit darker.
Cheers Gonzo.

As in an elephant is a bit taller than a cat

Gonzo, just looked at your sub on the SVS site... That definately wouldn't fit under our side table..!

Do you mean the thread or the length of the stud?

The sub is supplied with a set of spikes, and a set of small rubber feet.

 

[DVDANDY]

i mean the size of the stud as i have a set of nordest pulsar points that are 6mm and would want to put them on it

 

[DVDANDY]

the thread yes

M6 is normally the standard thread but I havn't measured the sub in question. Perhaps an email to B&W would help?
