Does anyone play two pairs of speakers at the same time?

holy cowz, i just setup my unused JBL305 MkI tweeter-to-tweeter to my AirPulse Model 1 (A200) and the increase in soundstage is incredible. deeper and wider... been thinking of doing this for awhile but all these XLR inputs-outputs are a bit daunting... i had better learn to make me own cables...
I had also tried my Yamaha DRX10 powered PA monitor as a 3rd speaker with varying results.. more bass, increased clarity (sometimes) and timber but the soundstage collapsed. I had also tried the JBL305s with the tweeters disconnected and pointed into corners for a swarm type sub arrangement.. more bass but again if bunged up the stereo image and gave me a headache..

I don’t know about extra pairs of speakers playing together but I recently heard the Swarm type subwoofer setup and bought it immediately. Multiple subs setup right is incredible sounding.

Yes, prep skool dorm room circa 1979
JBL- L110 and Infinity Qb with a 210 wpc Phillips amp..... Rust Never Sleeps never sounded better until I bought two pair of LaScala for the band PA

have fun, break rules, drink red wine blends, put cheap tires on the Ferrari....

As a bit of an aside, I miss my HQD and Acoustat 2+2, those were both good in the right rooms.....

i still have my 4 bose 901 series 2 speakers. i have it set up as the 'super bose system' as you older people will know! sounds good to me so i'm happy with it!!!
