#30 PSB Alpha S10: $649.00 Estimated Crutchfield eBay
Smaller model: the PSB Alpha S8 (ranked lower, estimated 3.2/5).

Cons: Rear bass reflex port requires ample breathing space from back walls to avoid port turbulence. Does not include onboard parametric EQ.
How it compares: Just above it: Polk Audio PSW108 - $470 cheaper. Just below it: SVS 3000 In-Wall - $1351 more.
