hi all,

 

looking to complete a home cinema setup and just debating putting the centre speaker (mine is a 7-6 but presume same concept / issues for the other 7-x speakers) IN a partition wall.

 

the front grille would effectively be mounted flush with the wall just beneath the TV, with the rear jutting into the media room behind the lounge where the sky box, amplifiers etc etc are all hidden away nicely (controlled via lintronic electronics)

 

anyone done similar ? Do i need to isolate the speaker from the wall (stud frame with plasterboard partition) or is it best closely coupled / damped etc ?

 

seems daft i have a nice flush to the wall TV then a centre speak sticking out 20cms plus mounting bracket, means it sticks out best part of 30cm

 

all suggestions / comments greatly received, thanks, David

The only thing I'd worry about with an active speaker is cooling when embedded in the wall.

That and the bass response.  Also, future access.

Thanks Jeff, yes fair point, but i think i've worked the cooling side out as the stud wall will have vents higher up to cover this and the wall will be relatively thin (10cm) so only half of the speaker is enclosed and the back still sticks out a bit.

the mounting braket will be bit of a custom affair to hold it to the back of the wall inside the media room (this is a self contained room, north facing against side of the house so is ventilated and contains all the AV and IT equipment for the house, so does not need to be pretty and can be purely functional) 

should i have it "free floating" or fixed to the inside of the wall ?

Thanks

Hi Dave

acess should be OK as above but the bass response is a worry for me!

Its a leap of faith as i can't easily test this, as once the hole is cut its done ! (Yes i know a good plasterer would make it invisible)

if i mount it to the wall will it make the wall vibrate with it? if its free floating will it rattle against the wall ?

im hoping with it being a centre which is mainly dialogue there is not tonnes of low frequency high volume sounds being oushed out, and i ncan wtweek the soind going to it to accomodate this a little, but the. I lose the quality / realistic sound

anyone done this or similar?

i know there are in wall speakers (including the b&o ones) but these have been designed to work this way whereas im trying to make a free standing one work in an enclosure so really breaking the design principles, but wondering if a small comprisie in quality will give the benefit in the aesthetics im after?

The other issue is the sound from the two drivers underneath the speaker. If the speaker is flush to the wall, you will effectively lose half of your sound!

Probably not half but some. Depends on where the crossover is to the front speakers, I am not familiar with the Beolabs in question. Might be able to compensate by setting the crossover freq for the surround processor for the center higher.

Not to mention the ports on the rear...
