Martin Logan Quest Z speakers




The Quest’s transparent electrostatic panel is curved in the horizontal plane (a M-L trademark) to give increased HF dispersion. The constant-charge diaphragm is segmented, using horizontal foam strips, to break up the inevitable LF drumhead resonance. The perforated stators (another M-L trademark) are finished in black insulating paint. The woofer is a 12″ moving-coil unit—identical, in fact, to the woofer used in the Monolith—and is mounted in its own sealed enclosure. The woofer and panel crossover networks, each 12dB/octave, are individually accessible via dedicated binding posts so that bi-wiring, or even bi-amping, is easily accomplished.
