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

Millercarbon, 

I wish I could could see the humor in your failed attempt to be funny.  Let people who are serious post here, because perhaps they have tried what the OP was suggesting and want to share their experience with others.  

  Classic  , i have  non-audiophile friends and they LOVE that set up.  

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....
