Martin Logan Summit X

Unparalleled Sound Inspired By the CLX
Amazing mid-range clarity and openness inspired by the CLX loudspeaker is only half of the story. Summit X is the first hybrid electrostatic speaker to bring controlled dispersion to low frequencies. Using a precision Vojtko Voiced™ crossover network to apply variable phasing near the crossover point, Summit X's Controlled Dispersion PoweredForce™ technology provides seamless blending with the XStat™ transducer. Four innovative modular feet adjust vertical dispersion over a 12 degree range, while the 25 and 50Hz level controls fine-tune woofer output to provide smooth, clean, and powerful bass throughout the listening environment.
