Why not use a sub bass or bass horn? Wee little cubes with over taxed transducers and poor transients are why your not getting a good match if running horns use horns.
In my experience with Lowthers, Voice of the Theaters, Klipchhorns, Acapellas, Avantgardes, and Beauhorns, no there are none fast enough.
The same is true at the other end. Only the Muratas super tweeters with nothing below 15k Hz works with horns or for that matter any speaker, and they aren't made any more.
Not sure how it works exactly but Rhythmik direct servo technology is a unique advertised feature that at a glance sounds like it should make some difference. Looks like a kind of negative feedback associated with the built in amp maybe? Not sure what makes theirs so special in that most power amps use negative feedback, but surely not all NF is created equal.
