Nearly finished an 18 month ball-ache of a reno, just needing skiting boards, curtains and finishing a pair of Ultimax 12" ported subs.

 

Speakers are a bit of a hybrid - Linkwitz LX521 with Minidsp 'cept the bass drivers which are Eminince Beta 15A I happed to have lying around - this is a low-as-possible-cost project. Amps are NAD receiver powering upper 6 channels, Minidsp PWR-ICE on the bass drivers. There is an Arcam receiver in there that will be used as pre-amp for movies. Still need to hook up rear in walls (budget Polk RC60i). Have wired for x 4 Atmos ceiling speaks but that might only happen a year or two from now.

 

Sounds pretty good considering the room, still need to move in a dozen Hofa diffusors and broadband absorbers I have stashed under the house. Nice comfy and quiet room though - underfloor heating, double glaze windows and R6 batting walls, floor and ceiling.

 

The pink ceiling...I lost that argument with my wife. 

Nice build, very unique bass driver arrangement.

I also went from PSE-144 to LX521, kept both. Curious to hear your impressions.
