Axiom Home Page Forums General Discussion Technical Questions epic master 350 -w3- question

That sounds like a question you may want to call Axiom about or send to Alan in a PM.

It looks like it only sticks into the wall 3" so I don't think the R value would be compromised too much, especially if you seperate the Insulation a little and allow it to form around the speakers back cover. I would also recommend looking for a suitable piece of plastic to act as a vapour barrier to surround the back of the speaker and have it sealing around the speaker wire as well. You wouldn't want too much warm air circulating around with the colder air behind that speaker.

Just my 2 cents.
