I don't much care about sound going into other rooms as much as I care about how things sound in the theater. Two of my walls are exterior walls, with just concrete backing - but they are 6" walls (because of plumbing runs) so i'll have a significant cavity behind these 3.5" deep speakers.
I was thinking of just building some simple MDF enclosures, sealing them to the drywall for an airtight fit.
I'm looking at using Polk 265RTs for my LR, and 255c-RT for the Center.
and the rears that are also external will be Polk RC65i's.
If it's a good idea to build these, how big should they be? I'm used to Car subwoofers telling you their ideal enclosure size, but I haven't been able to find that information for these speakers.
Thank you in advance!
Polk used to sell these "Performance Enclosure's" for the 265's just for that purpose, they are sized so that you would get similar performance to the floor standing speakers.
No longer available for purchase but easy enough to DIY. Size for the enclosure are under Specs in the link below.
