As part of a 5.1 setup,, I'm installing Pro-180RPW speakers in a 45-degree ceiling just above a 10 ft vertical wall for rear surrounds. There is no opportunity to place the speakers in the wall due to passageways interfering.
The Pro-180RPWs are designed for infinite baffle. I have an aversion to having the speaker backside exposed to the extremes of a northern Indiana attic, so I am considering building a sealed box of approx 3 cubic feet interior space to lessen the exposure to temperature, humidity, dust bugs and critters. Also, the master bedroom is next door, so placing boxes over the speakers would help keep sound from traveling through the attic. The box would have rockwool blanket inside to help with temperature and acoustics.
What do you think? Good thing? Waste of time? Positive or negative impact on sound?
Thanks for any competent guidance.
