I've had CLS speakers since 1990. At one point, I was saddened to find that my original 'stat' panels had degraded to the point of needing to be replaced. ML informed me that their original panel design has been improved to greatly extend the life expectancy of the metallic deposition - so be careful about purchasing older, used CLS's. Panel replacements are ~$900. Mr. Powers at ML Service Dept. should get a raise - he's awesome (hear that Mr. Sanders?).
Although I have occaisionally looked around at changing to some other speakers, nothing has come close to persuading me away from CLS's. I won't wax on too much about them as many reviewers have nicely captured my sentiments, but these amazing speakers can do things I have never experienced outside of live music - period.
After recently reading some reviewers having positive results from raising the panels, I made simple brick platforms 10" high and tried it out. Hey - what a big difference $20 can make! Don't know where the sonic benefits of a ~$289 designer stand might better my brick platforms. I have tight carpet on top of a concrete base floor, then the bricks, then the panels with spikes. For aesthetics, I used black material, corner braces, and velcro tabs around the bricks for a decent looking facia.
I tried out various raised heights up to 16" but found 10" to be the best for both seated and standing positions in my room. When raised above 10", the seated spacial imaging, and high freq's began to be compromised. I used (2) 10" x 16" x 8" blocks for each stand. More solid and 'sound dead' than any steel frame I could imagine.
Stand up! I'm surprised that there hasn't been a bigger to-do about raising the CLS's. With the stands, the 'sweet spot' is now not just limited to that magical 6" x 6" window while seated, and centered. I can stand up at 6' tall and get the same hair-raising sound curtain. Walking around, I notice the sound is MUCH better dispersed throughout my entire listening room. Even the output volume and curiously, the mid-bass have been appreciably increased. The seated, position is still as sweet as ever, maybe even with a degree of added detail - so I haven't lost anything by doing this.
After fixing on the 10" height, I found it necessary to tow-in a bit more (perhaps that is where my added detail came from) and I also decreased the top to bottom slant slightly. Voila! Now even my standing guests can be mesmerized by these crazy things, making a great thing even better. Now I feel like a dork for not having tried it sooner.
So if you haven't already checked it out, go spend the best $20 bucks you are likely to ever put into your stereo. Please let me know your results or if you have other comments on this!
After hearing Quads years ago, and going through tiring auditions of dynamic speakers, I realized that I would probably only like to live with an electrostatic speaker. The CLS is the only single panel speaker out there, and the design theory intrigued me. I took a load of CD's to the dealer and listened for 3 hours and still had a hard time leaving. This was with CJ-12's, very powerful tubes. I wondered whether my Audio Research VT100 MkII would drive them well but took the chance. Well, they are truly sonic nirvana after a year and a half with them. The ARC amp works well with them, driving good bass and highs, the highs being the more difficult end with the impedence drop to 2 ohms. They are incredibly detailed throughout the range and put the performers right in front of you. The impression of a third speaker is very clear, since many recordings have some parts on right channel, some on left channel, and some mixed to center. After 6 months of living with these, I talked to Roger Sanders, who invented the curved ESL panel, and who now builds Innersound flat ESL panel hybrid speakers, and bought a copy of his book, the ESL Design Cookbook, which I highly recommend. Well, the equilateral triangle setup he recommended widens the field to 60 degrees and eliminates room problems at the same time. This is definitely the most holographic setup for these speakers. They are really not so difficult to place as others have noted. Mine are 2 feet from the side walls, six feet in between, 5 feet from the back wall. Though I have considered a sub, specifically the REL Strata in pairs, the bass is satisfactory and these are supposed to be difficult to mate with a sub. They easily show every change in component up the chain. The only problem I have had is an inability to handle very high volumes without distorting the lower bass, but I get good volume for rock, punk, classical, and everything else under the sun. I love them. Though the ideal sweet spot in my room is seven feet from each speaker at the apex of an equilateral triangle, with the speakers facing you directly, they still have good off-axis sound.
These are some of the most incredible speakers I have ever had the honor to hear. The imaging is so incredible and transparent. Classical, Jazz and especially vocals come to life with a realism seldom heard at home. If you love cranked up Rock & Roll, buy the hybrid with a built in conventional woofer. The CLS's won't have the punch you want. But, if you want the most enjoyable listening experiance you have ever had, these are the speakers for you. Like a great love, searched for and found, they are not easily setup, but when done, will bring a lifetime of heart warming joy. Take your time and try a lot of placements, it will make a huge difference. Also, don't underdrive these. They love power and when satisfied, they come to life. By now you know, I love these speakers.
I have had a pair of the Martin Logan Clses several years ago. I did not have aSubwoofer at the time, and I sold them and bought some Audio Concepts Sapphire II which are exccellent dynamic speakers, and then Apogee Slant 6s which overall might be the best speaker I have ever heard. But if your into vocal and extreme detail as I am, nothing beats these speakers on earth!! Try them with Tubes, I am using a pair of monoblock Quciksilver KT88s (60 tube watts) and its awesome!!
Christmas is coming and I want to make myself a nice present! I want to get Cerwin Vega CLS-215 speakers. They are with 2 15" woofers and rated 500W! Does anyone know anything about them? How do they sound?Read More »
:yikes: :shocked: after all that too big! i going to look around some more but right now leaning towards the reference series of klipsch RF82.i know there totally opposite of what i was shooting for and not a big bulky 15" woofer but 2- 8" makes 16" right?so i lose some of the midrange but my bose 2 ...
