CLX: 25th Anniversary

The World's Finest Full-Range Electrostatic Line Source Loudspeaker

The World's Finest Full-Range Electrostatic Line Source Loudspeaker.

The CLX delivers the truth – the culmination of everything we have learned about electrostatic technology since we brought our first product to market in 1983. Purity of sound permeates your entire room and satisfies even the most critical ear. The new industry benchmark for resolving detail, CLX utilizes dual electrostatic transducers to render the most complex musical passages as faithfully as a crystal prism disperses the full color spectrum. This is the limitless spectrum of the CLX – the absolute truth in musical reproduction.

Running In
I am still running in my new CLX's and previously ran a pair of Summit's. Another week will cover the 100 hour mark and I can already hear a big change to the warmth and depth of bass. Wow they produce an intense sound that is so much more alive and detailed with an energy and drive to the sound never before heard with the Summit's. I am listening to them in a small room which is only 11 foot wide and 16 foot long and the speakers sit only eight inches off the side walls but about 3 feet from the rear wall. I was concerned that the bass response might be too strong with a large speaker in a small space but room interaction seems to be almost non existant. Although the speakers are fairly close together at 6 feet I am still able to get very good imaging but the sitting position is very critical. I am running a Descent sub with the CLX as changing from the Summit's bass response to the CLX's was quite a contrast. I will see how well the sub works first before considering a possible upgrade to the Descent i. So far so good but I am missing about 15hz with the sub swithed to 40Hz. I will let you know how I get on after a few more weeks running in.
