Louis was working on a super tweeter mount that would make it easy to install to the stock cabinets, for the ones that need more upper range. I think his newer Hemp drivers are supposed to be better for this kind of music as well. Since I do not listen to that kind of music, I'm happy without the added tweeter. Yeap I've replaced multi driver floorstanders that went down to 25 hz. Also large Magnepans have been up rooted because of the Omega /dual subwoofer combo. For me without a doubt it's the best sounding setup I've owned and also the cheapest!
Low volume listening has never sounded so good.
If you really want to enjoy Jazz,Classical and most genre to it's fullest you need a SUB with these speakers. Two would be better.
You will hear the foot tapping in some recordings but you won't feel it without the subs.
Good luck!
