I am almost finished with my room, just waiting for the wall treatments to arrive from GIK Acoustics. After they arrive I will do my final tuning but sure is sweet so far. My room is 12' X 14'.
I have 5 speakers on the floor, 4 ceiling speakers for Atmos and 3 subwoofers.
The 4 Atmos speakers (B&W CCM7.5 S2) are tilt able to the listening position. They are in line with my two front speakers on floor. Two front heights are between front speakers and myself, two rear heights are between the back of my head and wall.
Note: My experience so far with Atmos heights is sometimes spectacular, most of time not. Movies seem to embrace the Atmos more than music only discs, music only discs are little weak except for some exceptions, Booka Shade, etc.
The envelope of sound is very cool even when not hearing discrete artifacts.
The foundation floor speakers are still the engine of all.
My 3 subs, all REL S5 (rear sub), S510 (for front L/R) and S812 (for center) are really great. I thought that REL was crazy suggesting that set up to me based on a 12' X 14' room, but really glad I listened. They are tuned perfectly, they do not wall shake, there is just this nice layer of low frequency that ties the bottom in and pressures the room just right, they are not turned up to shake but on movies sometimes they do a little.
The front and rear subs used for the floor speakers are LFE connected from two separate sub outs of my AVR and High Frequency speakon cable connected to amp speaker posts. I had some minor feed back and by disconnecting the black speakon wire the hum went away.
The 3rd sub for center channel is NOT connected to LFE but High Frequency cable only, red and yellow to amp end and black to phono ground of AVR (another help in eliminating hum).
As I said in the beginning I am still tweaking it out with minor placement of speakers adjusting my brain to certain imaging and reflection. Did I say my sitting spot is off center, my right armrest of my chair is center, so the center of my head is off about 8-10 inches.
I have been successful using mono recordings to dial in the center image between left and right mains, so now my stereo image sounds better.
Since this picture was taken the two fronts are moved towards center about 2" from audio rack, the two subs are now angled diagonally, IsoAcoustic Gaia II feet have been added to the two floor standers, and the new carpet finally lays flat.
I have started to turn off my tweaking brain and start to just enjoy what I have, believe it or not this is challenging to get out of that head space to want to improve, not even sure I know what to improve anymore.
