Radical thought- Use 2 pair of speakers

This might be what you are looking for. Sound interesting, anyways.

A while ago, just for the fun of it, I did a "stacked" Eminent Technology LFT-8A speaker system. Had eight channels totalling 2,400 watts into 4 ohms pumping into them biwired. I tell you, it was one of the most wickely huge sounds I've ever heard from a system. There are many times I wish I still had it set up because it made me FEEL I was at a concert. It literally made "wall to wall" sound stage. I had two Vandersteen subs going as well. A system built for pure fun and I sure did have it! Enjoy playing around with it! This hobby is supposed to be fun!
Just throwing different brand speakers together may result in something similar to what the college cafeteria does with leftovers... could get messy.

Eldartford--interesting. My memory is not pinpoint by any means but I wouldn't be surprised if the Sweet 16 article dated from the very late '50's. I could research it but won't--could be that I am just plain wrong. Thanks for the info.

Tarsando...It was 1956 when I heard the Bose system at MIT...not 1961. (I mixed up dates of high school graduation and college!) If you google "sweet sixteen speaker" you will find that it was Jan 1961. You will also see a lot of interesting info on multidriver systems.

I guess I am beyond Radical, because I use 2 completely separated and dedicated audio systems for my own 2 channel surround sound.
Why not have one kickin setup in front, and in the rear, another kickin system.
The trick is to get the same sound,
patience and much listening period.
I use a single Stereo 500wpc.@4ohms amplifier in front,a lovely Velodyne F15ooR for the ground work.Mains are Klipsch ChorusII's with JBL L19 on top,then JBL L100 on very top,JBL are sideway's.
Rear another Stereo 500wpc.@4ohms amplifier and another Velodyne 15"sub. to keep the foundation seamless.2 15" horn loaded speakers on top of 2 12" 3 way speakers.
I simply send a loop from my Museateax Melior Pre-Amp to my Musical Fidelity pre-amp. Listening the whole room in Redbook,SACD or DVD Audio mode must be heard... if you like exactly what is on the Disc like I do,The Sony XA7ES plus Benchmark's Dac1 with Audio Alchemy's Data link(no signal loss)Transparent Audio's Super Power cord brings it like so many others can't.
It truly is like a metamorphosis occurs where by the notes seem to hang in the air as if suspended...
101db.Sensitive speakers with clean power and pure source,have that "Jump Factor" that very few speakers share.
Where every detail is reproduced clearly,like breathing, clapping ,drink glasses clanging together, cash register's, all backround sound's heard clearly.
The very inflection of the guitar or bass is represented as is the long decay, or delay...
If one system fills half the room(Robert Harley's Guide To High-End page 372 fig.A-5)
Then why not put another
sytem on the other side of the room?
I did, and after attending many Live events in Jazz Clubs or Out doors I have been very fortunate to see and hear some of the Greats.And now, I enjoy
that same Dynamic slam and clarity,the very essence of the MUSIC! Pro's use Line Array's to fill large area's;I just scaled the idea down to fill my room "EQUALLY" with sound.Result,No little sweet spot no,no,no the WHOLE ROOM is the sweet spot now!
