 Has anyone ever used stacked Quads with one pair on the original feet and a second pair raised on a stand just above the first pair? Not sure if this would work very well. Any comments woiuld be appreciated. Mike

 I've listened to a setup very similar to what you describe: the bottom pair was raised about 8" from the floor in addition to the standard feet and the top pair was suspended by a frame. The bottom pair would be firing upwards slightly (as per original feet) and the top pair would be firing horizontally. I did not audition this setup long enough to draw any firm conclusions but my first impression was that it sounded pretty decent.

My preference would be to make a dedicated frame and mount the panels directly in that frame.

Whatever you do make sure you don't have the split between the two pairs at ear level. And if you build anything I would be interested to hear about it and see some pictures!

Good luck.

 With my stacked pair I was able to adjust the tilt of the higher pair downwards,and to a lesser degree do some adjusting of the lower pair.The ability to play with the angle was absolutely necessary to get the best sound.I did sometimes add on Decca ribbon tweeters.
The custom made stand yielded vastly superior results when mounted on spikes-a world of a difference in favor of the spikes.This was odd because in almost every other situation I find that metal spikes do more harm than good.

 You can certainly run them that way but the integration of the Quads will be very poor.

The best approach is to stack both Quads so they are completely vertical with the lower Quad positioned so your head is in the middle of the lower panel. At listening positioning this will eliminate all lobing effects and will give a sonically seamless presentation, pretty much. This eliminates the very common but poor practice of 'tilting' the Quads, etc., to try and integrate the stack.

The down side to this approach is the stack will be very tall. About 7' tall. But no matter how you stack them it will be tall. I can't tolerate them stacked if you try to tilt the panels. They never integrate.
