It seems like all bookshelf speakers are overwhelmingly 2-driver and tower speakers overwhelmingly have a single tweeter up top and then various other woofers below. But point-source speakers are the ideal and ceiling and floor reflections have a huge effect on sound. Furthermore, the more drivers you have, the lower the distortion, and tweeters usually can do more SPL than bookshelf speaker woofers.
Why isn't the standard MTM configurations? Its seems it would be so much better just to have the same basic size speaker but with two slightly smaller woofers and the tweeter in waveguide for uniform dispertion up front, better phase alignment, and less comb filter from boundaries.
I'm sure there must be good reasons why D'Appolito arrays aren't the norm, I'm just interested in what they are. It seems to me that the advantages of coaxial speakers (e.g., Genelec Ones and KEF R3) are very compelling. D'Appolito arrays are a next best thing as far as phase coherency. Anyway, any thoughts on this topic would be greatly appreciated. I'm looking for some bookshelf speakers that can do some good SPL in a large room with subwoofers. Wondering why I can hardly find anything other than the old one mid and one tweeter configuration and can't afford the Genelecs.
