Amazingly clear and full. Massive magnet. Very noticeable upgrade over the Clarions I installed in a Koss cabinet years ago.

Very nice speakers with a very pliable cone and large magnet. Solid connection terminals not loose like many other speakers. Has a nice fiber washer embedded in the front of the speaker to eliminate rattle against mounting.
