Hey @erik_squires , I got the sub installed today but have yet to calibrate it. I was worried that "slim" meant wimpy...NOT. This thing is HUGE but manageable. In this pic of my back wall you can see:
1) The Paradigm 20 height channel for the right height channel.
(In the upper right corner of the pic you can see a glimpse of the Auralex Sustain Lens diffusor hanging as an "acoustic cloud).
2) The amps I am using for the rear surrounds and rear heights is blurry in the pic but is to the left of that height speaker. Those amps have a sub out ports, both are connected to the sub below.
3) The Monoprice SSW 12 "Slim" Sub (LOL).
4) Below the sub I have the tan colored absorbers on two inch spacers mounted to the wall.
5) To the right of the tan absorbers you can see my R rear surround speaker which is specially designed for wall mounting.
6) To the R of the subwoofer you can see two Auralex Sustain Pyramid diffusors which are back filled with polyfill so they double as bass traps.
I will calibrate the sub using the ARC room correction of those amps in the back of the room so it integrates with the rear surround and rear height channels. Then rerun Audyssey pro on the entire theater, Will report after it breaks in a bit.
