7. Comments and/or stories about your Martin Logan experience:
Love the sound quality of these large Electrostats; when hosted in a room designed for them, they really come alive.
Now with a full room treatment using >45 commercial products from RealTraps, RPG and my custom side treatments, the sound is superb and looks wonderful.
By designing and building it myself, I finally got the center channel I always wanted. The results are incredible.
Bass performance is incredible thanks to the large Infinite Baffle sub paired with an 18" sealed sub symmetrically placed at the room's rear and augmented by dual MidBass Modules behind the main seats; there is deep extension along with the sensory impact that makes music and movies come alive.
