I have the following Def Tech Setup:Attachment 239809
1 Procenter 1000
2 Promointor 1000 (fronts)
2 Promonitor 800 (Surrounds)
2 Prosub 1000 Subwoofers (stereo subs) 80 x-over
*rest of speakers at 80 Hz also (receiver won't do multiples)
Both front and rear speakers are mounted to Sanus speaker stands. My system is powered with a Pioneer Elite VSX-21Txh.
I have upgraded from the Procinema 60 to the Procinema 800, and now my mixed system. In my room (12 x 19) I noticed that I was losing base strength on one side of my room (initially had the Prosub 800). After replacing the 800 with two 1000's, I have the whole upstairs shaking.
