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

Back in the early to mid 70's, some dealers would stack two pair  of EPI 100"s with excellent results. Often besting the stacked Advent pairing. Although the smaller EPI woofers didn't have the bass extension of the Advents.

Why is it people like a blended whiskey ? Or a V8 in a Chevy Monza or a Maverick? Life is complex, the grail elusive....

Yeah @simonmoon, the Danny Richie Tech Talk Tuesday videos are fantastic. Tekton owners might want to not watch them, though ;-) .

 I have attended many live classical musician and jazz concerts. There are many of the same instruments with different manufactures playing together at the same time creating beautiful music. I always thought a speaker for each instrument playing only that instrument in it's exact spot would be an interesting experiment. I have owned many pairs of speakers and amplifiers, I have also played up to 7 pairs of various speakers set to the same volume using a spl meter at the same time. Most combinations don't sound better than the single pairs, just different. However some pairs have sounded decidedly better in the full frequency range and on various music sources.  It's a hobby and a blast messing around. I have also been doing this for 50 years and still enjoying myself. Have fun, but remember live is best and at home it's all about the music. Stretch your ears.

*LOL*  As for the latter...how can you tell the difference between 'that'...and one that isn't?!  They Always seem to be wound up like a tin toy....*L*   They make most breeds act like they're on 'doggie downers'...

Anyway, back 'on topic'....

2 pairs of 'matched' omnis'....small sub for the 'bottom'....active eq.

The only thing I'd fault Linkwitz with is different pairs F & R....

My 'reference speakers' are 3 pairs for H, M, & B; same formula as the omnis'....

I have a pair of small Maggies', and No, I wouldn't subject them to 'competition'.  Dipoles and direct radiators conflict by nature; the K's will drown the Maggies' subtlety....;)

Yes, I have an attitude about 'these things'....just like everyone else around here. *L*

Nothing personal, mind you.... ;)  I just needed to toss my wooden shoes into the gears....
