I posted in the Audyssey thread but there doesn’t seem to be many who have tried adding a sub-woofer to a center channel so I thought I would check with the DIY crowd.

My thought is it it would just look like a single speaker to Audyssey. The CC now becomes a 4-way which granted is more complicated, but with an 18 db slope at 120 0r 150, integration should be pretty good and not much different than the front and right speakers that include 12” powered subwoofers.
Thanks.

I use an Onkyo PR-SC5508 and after running Audyssey MultEQ XT32 again after adding an 18” sub-woofer to my system, notice the center channel crossover is set at 150 Hz.
I am currently running a single sub-woofer and it is installed in the front of the room to the right of the center channel and while the dialog sounds fine now I can hear some CC content coming from the sub-woofer. I am concerned as I add additional sub-woofers farther from the center channel, the content below 150 Hz will throw off the sound stage.
I have an unused AuraSound NS10-513-4A 10” sub-woofer in a 1 cubic foot sealed enclosure I could add. I would put a crossover in the chain between the processor and the amplifiers, running 150 and up to the center channel and everything below to the 10” sub. I could still set the Onkyo crossover to small with 80 Hz and below to LFE. This would keep the center dialog, especially male voices, tied to the center channel. I also have a Scan-speak Revelator 23W 9” Sub w/9” Passive Radiator 23W in a 1 cubic foot enclosure I could re-purpose if needed.
I run an Infinity Compositions Prelude system. The Compositions Prelude Center Channel Model P-CC specifications:
Frequency Range: 80 -20,000 Hz, 120 – 20,000 Hx +/- 2 dB (-10 dB @ 80 Hz)
I have a couple options for crossovers including a Bryston 10B sub (RCA) and a Rane AC 22B (XLR). I was planning on using the Bryston for a 2.1 system but assume it is the higher quality crossover. I have balanced outputs and inputs on the Onkyo and Bryston amps so the Rane wouldn’t be a problem to configure either.
Thank you.
