Hypothetical scenario here:

Out of curiosity I was wondering what the sonic result would be if one were to employ two planar speakers each for front left and front right. I'm curious about this because I had a similar setup in my old system when using conventional speakers.

I had bought a new A/V receiver and was running a pair of self powered fronts out of the preamp section of the A/V. This left the front speaker amps idle in the A/V receiver. One day I decided to hook up my old BOSE speakers to the front terminals and run them outside and a bit behind the self powered fronts. After comparison, I found I liked it better, so I kept the setup.

Today, BOSE's are gone, self powered fronts moved to the back, and a pair of Magnepan 1.6's are front left and right, again via the A/V pre-outs into a separate amplifier. Once again this leaves the front amps idle in the A/V receiver.

The A/V receiver amps (130 W) could not probably handle 1.6's, but might be able to do OK with a less demanding planar like Magnepan 1.2 or MMG or MC1. Question is what would it sound like.

To a non educated one like myself, I would think this "horizontal stacking" would result in a wider sound stage and an expanded sweet spot listening area. It would be like having one very large planar speaker on each side. Or would it? Or would they cancel each other or result in other negative effects beyond my knowledge to describe.

Just a wonderin'
