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.

Thanks for posting again what I have posted many times.  As a former dealer myself, we had FOREVER to listen to various pieces when the door was locked and BOY, did I get a fast education.

Yes, the 901's were amazingly bad--beyond anything we imagined, actually.  Also, many other speakers we "loved" (Advent's, Klipsch, etc.) were so horrible it was painful for me personally to learn how "uneducated" I was, and I have been playing music in bands since I was 10!!  I sure thought I knew what was what, but one listen to the Audio Research/Magneplaner system brought me to my senses quickly.

As for boxes, Mr. Robert (Bob) Fulton had a couple of boxes that were not bad--80's and 100's, I think.  Today, boxes are probably better, but you will never improve upon Maggies, IMO.

Cheers!

 i’m not a big fan of that GR research guy. Some of his techniques like the one where he used hey antenna meter from an old receiver to show you how radio frequencies affect speaker wires was a little goofy. Here’s a Website that I think the author has more chops the good old boy Danny.

But the videos I linked, are very simple, well used methods of measuring speakers. 

There is not much subjective opinion in them. Anyone, testing 2 tweeters mounted on the same baffle, will get the same results as Danny did. 

Anyone can repeat his test, and measure the comb filtering, the loss of high frequencies when 2 pairs of tweets are connected, and the improved frequency response when 1 pair of tweeters are disconnected. 

And as far as the other site you mentioned, you are correct, there is a lot more info there. But Danny's vids are not meant to replace much more technical sources, only to explain to the lay person what the problems are with running multiple drivers.

I am not a super fan boy of Danny's, but I can guarantee, he has probably forgotten more about speaker design, than many respected designers know. Have you heard his NX Otica's? If he is lacking knowledge as you say, he sure did get lucky (by random?), in designing a kit for $3000, that will stomp pretty much any $10,000 speaker.
