I've rarely been impressed by Legacy show demos either, although the clearest most convincing bass I ever heard was from Whisper XD at the show in DC, ~2013?
Sometimes I've even been turned off by Legacys at shows (original Focus SE with planar midrange at Axpona Atlanta trying to play Dizzy Gillespie harmon muted high notes - total failure!)
Doug Brown, the former Legacy VP of Sales told me that the demos at shows are always brand new speakers, never broken in. Add brand new electronics also and you have a constipated confused hot mess. It's actually surprising how good it does sound considering that.
When I got my Focus SEs they were 4 years old, I am 3rd owner, but they still needed 20+ hours of hard beating to break in (again?) I thought they were damaged when I first got them because I assumed they were already broken in and they sounded like crap. Once they were fully broken in they are very rewarding, a great value, imo, especially for symphony music there's nothing can touch them under 10k.
But nothing's perfect, they have 4th order crossover filters throughout, typical of all modern speakers. Focus 2020 had shallower filters on mid/tweets and was more harmonically transparent despite having far lower resolution drivers. Steep filters mask some harmonic and spatial details, but today's contemporary music requires it to protect the drivers. And it's 30 something DINKs that buy the new high end speakers, and they listen to rap, powerpop and EDM. Sell 'em what they want. But despite similar flat FR, steep slope modern speaker design formula, Legacy's comparatively larger drivers and larger boxes make them sound more musical than those who target WAF buyers.
