I've heard the Trios with Basshorns several times. They don't sound seamless to me, just loud and disjointed. The cheaper Volti's sounded great to my wife and I as well as friends. Testing was with percussion classical, rock and jazz. No listener fatigue with the Volti's.I’d add that Avantgarde is really the only commercial horn that is buyable today with dynamic driver company service and dealer dynamics.
