Magnepan, though not on the list gives a lot of bang for your buck, in highly detailed sound. With the unique sound of dipole bass and ribbon tweeters, however they do have some limitations. Which why I replaced my Magnepan 3.6s with JBL 4367s which is based off the M2 Project.
However before you think these two way horn speakers, have a studio sound from the eighties because of their outward appearance, think again. JBL and Harmon put their latest technology into the optimizing the horn so it has a wide open sound, with no honking. Plus the 15' dual drive woofer and it's 130lbs cabinet can really put out some bass if needed without the old JBL colored sound.
I've heard a lot of various expensive speakers over the years, this speaker would match or beat most of them. I've seen other owners say the same thing one was on the Audiophilac youtube channel with a modified M2 design. Also no ringing tweeters, it uses two annular tweets in a compression driver, which has incredible dynamics, and can play very loud with very low distortion.
