Ceiling / wall speakers acoustic performance?

Question

I heard that when mounting ceiling or wall speakers you'll get better sound acoustics and speaker performance if you insert insulation or some other type of baffeling material to help tune the speaker. Anyone ever tried this? Does it help?

Answer 1

Yes, In most cases it should help. Check the recommendations of the manufacturer. Some speakers are designed to work in open spaces. Most in walls are designed to work IN walls.

If it is new construction I  usually build a box 1ft X the width of stud or joist out of MDF (medium density fiberboard) Then I caulk the box and put insulation inside it. This will dampen resonance and inhibit the sound from traveling up into the attic or walls, and coming out into nearby rooms.  

You will also want to put a protective cloth around the speaker if it is going to be exposed to any loose insulation. Better yet is to use a rear baffle. This is a must if you have blown in insulation in your ceiling. Many inwall/ceiling speaker manufacturers make these. You can find them online at Partexpress.com. or check with the manufacturer of the speakers you are buying to see if they make them.

Answer 2

Of course a speaker needs a enclosure, who hasn't enclosed a speaker and gotten worthy sound.

It is best to leave in wall or ceiling speakers to a professional if you want proper sound.
