Default Was it worth it?

> Goodness, now I see where the beam splitting is occurring. So, was it worth it? Listening impressions, compared with other ESL?
Tosh,
Since I haven't had an opportunity to audition other ESL's, I can't say how mine would compare. I suspect mine would have the nicer bass but a fully open dipole would probably create a different (better?) sound stage (I can only wonder). I did hear some smaller Martin Logan home theater speakers playing at low volume in an hi-fi store once but there were other speakers playing at the same time and I couldn't really judge their capabilities. I can say that my ESL's are faster and more detailed with warmer, less resonant bass than any of the conventional speakers I've owned (Sony UH60's, DCM Time Windows, Altec's, Klipshorns). Diana Krall's voice now rightly sounds as good as she looks and her piano has attack like you wouldn't believe. Ironically, I think my speakers' greatest weakness (narrow dispersion) is also one of it's greatest strengths. That is; they radiate laser beams of sound so you don't hear as much reflected, late arrival sounds (as with conventional speakers) which I think muddies up imaging and detail--- so, imaging and depth are almost supernatural as long as your listening position is at the focal point--- moving out of the focal point, the top end falls off sharply. A friend who heard them called them "remote earphones". OK.. they're useless as party speakers but they're magnificent if you just want to sit in the focus and listen to music.
YES, it was worth it!

Default Foam strips or dots

Wachara C.,

Thanks for your complements on my speakers. I used 3M foam foam tape .062 inches (1.5748 mm) thick. Since dots would take up less area than strips, it seems logical that dots would let more diaphragm move for greater efficiency and probably also lower the resonance frequency... both good things, especially the lowered resonance frequency. In my case, however, my stators were not quite flat (had some ripples in the metal) and with such close spacing, I figured I needed the extra bonding surface provided by the strips to help hold the stators and diaphram at 1.5 mm apart (didn't want to chance the diaphram contacting the stators at high volume levels).

I'm no expert so please seek others' advice as well.

good luck with it!

Charlie
