RE: Stacked AR's anyone?

Posted by hahax@verizon.net on November 9, 2016 at 20:41:21:

There's no way to get the geometry of a true D'Appolito by stacking the speakers. First the midranges are too far apart and in true D'
Appolito they are as close as possible(preferably a tweeter diameter apart). Second there are two tweeters is the wrong physical relationship to the mids. A D'Appolito only has one tweeter. Without the correct geometry the D'Appolito dispersion will not occur. You'll just get unpredicted interference affects between the drivers, or as the late, great editor of Hi Fi News, John Crabbe, called it, a sonic wodge of sound when describing the imaging of the AR LST speaker.
