"I think the best bet is ensuring there isn't a possibility of standing waves from forming in the enclosures in the first place"
Right! And that means improving the impedance match to the air or increasing the loss of the radiator. Or both. Ya' gotta keep the effective Q down...
I think Quad has or had some scheme using a delay line that mapped the size of the driven surface to the frequency components. That makes sense to me as it should make the radiation resistance more real and consistent. I wonder if you couldn't do the same sort of thing with dynamic drivers in an array on a panel. Sort of a sweet 128... We can make low power amplifiers really small and cheap and if the array was circular each Amp. could run several drivers at a given circumference.
And then, of course, we totally damp the back wave or put the whole Mary-ann in a wall so it feeds two rooms. Or use horns...
Meanwhile, I've found that the only speaker topology I really like long-term is sealed "acoustic-suspension" styles. They just sound truer to me in an actual room than other styles. I think that well implemented horns (Geddes?) might also work but I've not heard them.
And "in the room" is a huge factor. At one time I has big ESS speakers with a Heill (sp?) tweeter and TL woofers. We were moving around a bit then so I had them in three houses and they almost worked in all three, but not quite. I replaced them with Infinity quantum 3's and was very happy. BUT the interesting thing was that if I opened the sliding door and sat out on the patio the ESS's really sounded like there were live instruments playing in the house. The Infinity's sounded like a good stereo was playing on the house under the same condition. But sitting inside they flipped and sounded like you were more at the original venue and were far more enjoyable and less irritating.
Which is a long-winded way to say that you have to match your tastes AND environment. I suppose it's obvious but some of us are slow... By the way I happened to go to a show at the Griffith Observatory during all this and they were using small banks of ESS home speakers, the one's with a port, at each corner for sound. It sounded wonderful!
