Martin Logan CLS IIz Speakers - The Best Vintage Electrostatic


These were my reference speakers for several years. 

The midrange is hard to beat, resulting in some of the most realistic guitar strings and saxophone you'll ever hear from *any* speaker.

They do an especially amazing job with jazz and vocals and will raise the hairs on the back of your neck!

Not so great for super complex orchestra pieces as they will get overwhelmed. And while they have realistic amount of base, you'll want to match with a good subwoofer to get full range "impactful" sound.

CLS speakers in general, while being able to reproduce music with outstanding realism, do not play loud.   If you like your music loud, the CLS's are not for you, and you'r likely to damage or distort them. 

These are model IIz, which is the finest out there. They are in impeccable shape, both electronically and cosmetically, with only the slightest signs of use. 

Flat rate shipping in the contiguous US $600 (Alaska & Hawaii or International please contact us for a freight quote).

More from Martin Logan:

In many ways the heart and soul of MartinLogan. The CLS IIz projects musical passages as faithfully as a prism disperses the colors of the spectrum.

The industry standard for resolving detail, the CLS IIz's curvilinear diaphragm reproduces the entire musical range. Free of crossover phase anomalies and multi-driver distortions, the CLS IIz is capable of revealing the subtle holographic magic within the music that transforms the experience from listening to "being there".

Launched in 1992
Price when discontinued: $5,995.00 (Approx. $10,000 in today's dollars)
