CLS IIz

Classic Full-Range Purity

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".

Dear Martin & Logan I have had the CLS IIz's in my sound room for over 5 years and can't say enough about how these speakers handle sound. Although they are not an efficient speaker it's nothing that respectable tube gear can't handle. I would like to say that those nay sayer reviewers that report that "they don't rock", have not placed them in the correct room with the correct acoustic treatment and bracing. They are like a good wine or brandy... "They just need to breath!" I find them to have an incredible sound field and deliver a full range of micro and macro dynamics without adding color or signature to my recording. Note: I feel they are the best speakers for handling the difficult sound spectrum found in trumpets and excel with ease at making strings sound so natural and effortless. It has been a while since I have thought about my CLS IIz's, since I find that when you get sound correct, one tends to go on without looking back. Additionally, Like most, I generally listen to music with my eyes closed and often forgot all about them because they are simply not there to find. Just a huge wide sound with a complete sense of being in the front row or floating above (Depending on the recording). At times, I swear I can smell the singers perfume and see the direction that he piano is facing. It's a shame that audio equipment such as this treasure get left behind in the wake of the re-invention world we live... Thanks for the many music journeys.
