Has Anyone Ever Run TWO Identical Pairs of Speakers ?


I’m considering buying an extra pair of tower speakers identical to the ones I currently own. I would wire them as 4 ohm speakers powered by about 250wpc,

Each set of two speakers would be placed next to each other so there would be 2 identical left channel speakers and 2 identical right channel speakers, with each pair separated by about 1/2.” 
My listening chair chair can be as close as 8’ from the “center” of the speakers to as far back as 20’ from the “center” of the speakers.

And the actual distance between these two seperate pairs of speakers could range from 6’ from each pair to as much as 18’ for each pair. I would of course spend a great deal of time ‘dialing” them in for the best sound.

Has anyone ever tried this, and what were your results?

I’d appreciate your collective informed thoughts.

Yes I have run two pairs of  klipsch KLF 30  and Two  pairs of klipsch  CF4 together side by side 2 for left and to right but with separate amplifiers the same preamp 
first pair run on balance XLR to preamp Parasound P6 XLR output second pair run on RCA To P6 RCA output 
the goal here is make-sure  all speakers tweeters are on the same ear 👂 level believe me it doesn’t have to be the same speakers 
I have try klipsch chorus ii and KLF30 combo klipsch KLF 30 and CF4 combo and forte and chorus ii combo…… if you set them right you will never go back to single speaker again 
the benefit outweigh the lost 
any 2 channel preamp with balance XLR and RCA output can do that not on AVR though 😂😂😂

I have a pair of Martin Logan’s ESL X’s and a pair of Vandersteen 2’s and running them with VTL mono blocks and I have to say when they are all on the dynamics are impressive and the bass response is awesome I haven’t played with placement for depth yet, it’s a work in progress and now I just repaired a pair of Thiels with repair work done by Rob at Coherent Sound (awesome service!) and look forward to listening to them as well just have space limitations.
@jasonbourne52  You are correct.  Stacked Advents were the bomb back in college.  Henry Kloss was a great guy as well.

Years later we found out that the speakers were pretty bad--there are MANY that are much worse, they they are pretty bad.  You have to actually LISTEN to them with good hardware to figure it out, but like most box speakers, they are pretty bad ("bad" meaning "inaccurate reproduction" of the music).

Still, back then they were considered quite a breakthrough, and if you could afford the better walnut cabs, they even looked nice.

Regarding stacked, yes, there were many discussions back then of how tweeters should be aligned, etc., how far away, etc., etc.  

As for various comments on "tall" speakers, gee, wonder where they got that idea?  Was not from Jim WIney, I am sure.

Finally, regarding stacked Quads in the HQD system, we made some of the stands for quads for Levinson (VERY slow payer) and some of the 24" Hartley woofer cabs. We listened to them next to Maggies.  Even back then we could easily identify listening fatigue from the Quads, which are shrill and have a number of other issues regarding delay, etc., that you can easily hear.  The Decca ribbon tweeter in the middle of the stacked Quads was interesting.  Running them with Levinson gear back then (when it actually worked) made the sound so bad we had to turn them off. 

REALLY bad!

Side by side with the Magges...NO contest.

Cheers!
It'll be a bit like Tektons.

No it won't.

Just because Tektons have quite a few drivers in them, does not mean they are in any way similar to have multiple speakers stacked or side by side. 

Please watch the vids by the designer, Eric Anderson on YT on the theory behind the design. 

Bottom line, Tektons are not just a bunch of drivers stuffed into a box.

I'm not even a big Tekton fan, but lets not compare them to stacking speakers. 
Here is an informative video by GR Research on why 2 tweeters don't work. This is describing why they won't work in the same enclosure, but the same concepts translate to 2 pair of speakers, stacked. 

In fact, most of the problems he talks about, get worse the further the tweeters are separated in distance.
