Based on a quick perusal, the article appears to advocate long familiar arguments. While there are some manufactuers who are advocates of coherent time domain response in loudspeaker design (Vandersteen, Thiel, etc.), there are a slew of manufactuers who are not. The Quad ESL-63/988can...

I am happy with my CLS but if that is what they can do to improve the speaker, I am all for it!! :rocker:

Neil, I agree materials and processes have improved but I think the fundamental trade-offs in electrostatic speaker design -- stator spacing, panel size and form, bias voltage, etc. -- have tended to constrain what is practically achievable. All of these factors were explored systematically by...

I think you are on to it, Rich. It won't be easy to substantially improve on the CLS without making major changes to the design. Based on the Gayle Sanders interview about the nature of today's speaker market, I suspect that making the CLX much bigger than the CLS was not a design priority and...

I have a pair of original CLS but my interface box is similar to the one you show for CLSII-- that is, with transformer on the inside.

Original CLS, Interface Power Supply S/N 2844/45. I have new panels which are still breaking in; the old ones were from 1991 and still working ok.

Sorry for joining this discussion late, it is quite informative and I thank Jon for starting such an interesting thread. I would like to add a little of my own recent experience regarding dipole placement and wall treatments. I recently acquired a pair of CLS (original). After installing new...

Glad to help, I wondered about mine too when I opened them up. I don't know why they dropped the HV-- maybe it was because the panel output was sufficent at the lower HV or maybe there were problems with migration of charge on the panel at the higher HV. I guess we will never know...

I don't know of any other than the Sound Anchors you mentioned. Arcici made a stand for these but it is no longer available. You can make your own stands, of course, see elsewhere on this site for how one person did this. One other option: use a low profile subwoofer and mount them on top...

To get an accurate measurement, you will need to use a voltmeter rated to measure in the kilovolts and a HV probe...

I don't think you have problem. The modifications done to my CLS power supply appear very similar to yours-- there are "missing caps" and diodes and a jumper added. I emailed Jim Power a picture of my CLS crossover and he indicated that ML had modified the power supply. Jim told me that the...

I agree 100% with all of the praise for Jim and the service department at Martin Logan. Jim is an outstanding resource to the owners of Martin Logan loudspeakers. He is very willing to lend his knowledge and expertise to almost any problem no matter how small. He has helped me get a pair of...

After several weeks of vacuuming, heating, and plucking stiffener tape from the 16 year old panels on my original CLS, I decided I could not get any more from the old gals and it was time for a change. I talked with Jim Power last week and on Monday my replacement CLS panels arrived. How do...

That's ok, I appreciate your inputs Neil!

You have the Sound Anchor stands, yes? Do the stand assemblies bolt to the CLS panels directly? Are the stand holes slotted at all?

Interesting, I just measured my CLS and I get 2.25" vertically but 18" horizontally, center to center. Measuring horizontally with the interface in place is a bit more difficult but I double checked it and it is 18".

I am interested in possibly getting stands for my original CLSs. One question I have concerns the Sound Anchors stands and it may apply to other stands for the CLS as well. Does anyone know whether the power supply/interface module T-nut locations are the same for both the original CLS and...

I have had similar speakers to you in the recent past and my experience mirrors yours pretty closely, especially with Magnepans. I had Quad 988s and Magnepan MG-IIIas. I think your characterization of the Maggie 3.6s applies very well to the MG-IIIas-- you really have to play them loud to get...

Here are some pictures of my other equipment. You can see a close up of the Roksan Xerxes turntable and SME 309 arm. I have been at this since the early 1970s. In addition to that 'mini statement' that I sold back in 1999, I have had all sorts of other high end speakers including Magneplanar...

Thanks for the tip on the stands, I'll check em out! :cool: You and I have tread a lot of the same ground! I became frustrated with noisy tubes in the CAT preamp and replaced it with Mark Levinson a No. 26 and 25s combo. I liked these a lot although I got tired of the Camac connector...
