@rixthetrick: I take it you live in Texas. Have you visited Danny Richie at his GR Research facility, located in Iowa Park? He welcomes visitors, and will demo his loudspeaker models for you. He sells his designs as kits (only), so they aren't for everyone. But you can at least hear what is possible at various price points.
And not to disparage Eric Alexander, but Danny considers loudspeaker enclosure resonance a very serious matter, his designs addressing it to a degree seen in few commercial plug-and-play offerings. Another designer who feels that way is Jim Salk (as did Albert Von Schweikert. Of course Wilson and Magico do, but you pay dearly for their approach.). Look at the bracing Salk employs in his speakers, the best I've ever seen. The enclosures he builds and into which installs Rythmik sub kits are insane, the best bracing I've ever seen. I copied it when I built my Rythmik subs; cross-braces every 4", front-to-back, left-to-right, and top-to-bottom.
