Are Martin Logans considered polite?
Hi all ML owners,
I have had been using my Sequel II - Martin Logan’s fantastic ESLs since Aug. 1990 !!! I had my first issue with one panel only after 3 months of use, (Balance issue) I noticed that the sound "moved" to the left area of the speaker yet in almost full db., I have contacted ML and got a brand new pair of panels shipped by airplane to Israel free of charge, after installing the new pair the speakers worked 29 years without any degradation signs until recent year after moving to my new home by the sea-shore for 7 year... that the sound got weaker and weaker from the static section yet evenly heard. |
Martin Logan's can sound recessed in the upper mids/highs, especially in the highs decay, with tube amps, because ML esl's dive down to .9ohm impedance in that area and tubes don't like those sort of impedance loads. Roger Mojeski's tube amp could do ok as they have 2ohm speaker taps, but then wattage may be limited to low to normal listening levels, e.g. no parties. Cheers George |
My problem with MLs is not at the top, it is at the bottom. ESL panels get very directional over 10 kHz. Unless you are right in front of them they are going to sound rolled off. They are quite capable of getting over 20 kHz. To fix this problem ML curves its panels and crosses to a sub. The inventor of the curved panel Roger Sanders will explain why this is a bad idea
http://sanderssoundsystems.com/ . Acoustat used angled flat panels which in the larger versions like the 3 s and 4 s did a credible job. Soundlabs carries that approach farther by using more angles in more partitions creating a speaker that will cover 45 degrees which is enough. Too much dispersion is just as bad as too little. What ESLs do not do is make the high end obvious. As good as Manepan's tweeter is, and I think it is the best magnetic tweeter available, it stands apart from the rest of the speaker. But you can be anywhere in the room and you will hear it. I find the speaker sounds its best if the high end is rolled of just a bit. 3 dB down at 20 kHz with an elbow at 3 kHz. |
