Need help on installing in-ceiling speakers in an insulated ceiling. Will extreme temperatures (cold in winter, hot in summer) effect performance of speakers? Do I need to cover backs of speakers to protect them from blow-in insulation? Thanks.

I've never had any problems from the cold and heat.
With blown insulation, it's a good idea to box in the speakers. If you ever have to remove one for service, it will save a HUGE mess!!!

Should be a ble to purchase a vapor barrier or back box from the in-ceiling speaker manufacturer. It will box the speaker in an avoid the insulation falling all over the place.

Niles and and several other manufacturers have barriers to keep the big chunks out of the surrounds. Why? We're kind of too lazy and not paid enough to make or install backboxes. Besides, many in ceiling speakers sport infinite baffles.

We actually cover the speaker with insulation in a somewhat weak attempt to keep the heat from the attic from drying out the surround. This seems to work too.

Nice tip: cut the hole, don't throw the cut piece away but offset it in the hole to keep the blown in stuff in the attic till you stick the speaker in.

You could easily form a cage of aluminum window screen, which would hold back the insulation, but not act as a volume limiter for speakers designed for running without an enclosure or back box.

I had to install several recessed lights that were not insulation-contact rated in an upstairs ceiling. I made cages from 1/4" mesh cloth to keep the insulation 3" away. The inspector was very impressed.

Then cover the screen/mesh material with vapour barrier (plastic sheeting) material to keep attic air and the insulation out of the back of the speaker. Vapour barrier is a low cost solution to back boxes. Just make sure that you tape all of the joints in the vapour barrier to make sure that you have no air infiltration.

Depending on how much you want to spend. The Bose 191 Inwall/ Ceiling speakers are great. I am using them as surrounds but have heard them as main fronts. Typical Bose they have their own wave guide box so all is protected. They also come with Grills for Wall mount and Ceiling Mount.

Larry, you are just so cool. Don't you love the look an inspector gets when he realizes that you really want to do it right and want to do what he is asking for? That you are not asking questions just to start an argument?
A good answer is easier with a clear question giving the make and model of everything.

Oh, yeah, the topic.

You can even spread a cloth up into the hole to help keep particles from banging around on the back of the woofer. Somehow I did not do this for years, and had no problem at all, though.

The cloth should be light and see-through. Maybe that is not exactly right, but it will work well.

Not here to bash bose but I was at a customers who bought a buch of these 191s. They are even more comical than the cubes. The whole speaker looks like a toy. And they use the same 2" dirvers that can be had as replacements for $3.00 each.
$12.00 worth of drivers and some plastic for $300.00.

Can you list a location to purchase these replacement speakers ?

I do believe these are upgrades for the blose. The actual replacement is a '72 Dodge Dart horn (mopar part#327754-2) but the partsexpress will do if you don't mind the improved sound quality.

Really. No kidding.

Clear off the blown in insulation and cover the area you want to put the speaker with a nice long piece of 24" wide, thick pink insulation. The width works in 16" centered or 24" centered trusses. This will keep the loose insulation from falling through the hole you cut or covering the speakers and getting on to the cone. It will also allow the speaker to function properly. Most ceiling speakers will work infinite baffle without an enclosure.

Many manufacturers of mid to high end ceiling speakers offer some type of enclosure for their speakers. SpeakerCraft for example has enclosures designed for almost all of their models.
