Electrostatic speakers and low volume resolution


I've used electrostats almost exclusively for over 35 years and am just now questioning whether it is my somewhat compromised hearing (73 yrs old), the nature of that type speaker, or both that lead me to this question. At "normal" listening levels factors like detail, resolution, timbre, etc are excellent. At lower volumes, though, I lose these attributes. I realize that my age related hearing deficiencies could account for these loses but am questioning whether the nature of speakers themselves could be a contributor.

It's been awhile since I've used conventional speakers so my memory might be lacking but this didn't seem an issue when using them. The two that I owned and recall having the best sound to my ears were the JMLab Electras and the Jamo Concert Eights. My current speakers are the Martin Logan Ethos' which replaced the Odysseys that were in the system for 12(?) years.

For various reasons I need to listen mostly at reduced volumes, so, before I start looking to trade my Ethos' which I very much like, btw, for something like a good pair of stand mount dynamic speakers, I'm asking for input.

I've become a strong believer in the part that all frequencies play in such important factors as timbre, even, or maybe especially, those beyond our sensory capabilities. As was discussed earlier, the base frequencey of most any instrument or voice falls within even my upper audible range of about 8-9000Hz. Their associated and critical upper harmonics, though, will far exceed these values.

For this reason I'm convinced that their enhancement can be valuable to realism without, as far as I can see, much potential downside. I will be trying it then but I still need some guidance on their use. First, I've read that a x-over is necessary which I can understand if one decides to use ribbons for example. If one were to use piezoelectrics, though, they are LF limiting by their nature. I'm not sure they are the best choice though.

Anyway, my concern remains re the use of a crossover; I don't want the transducer panel robbed of any portion of the delivered upper frequencies so a crossover doesn't work in my way of thinking. As I also remarked on before, I see the piezo as a capacitor which if installed across speaker terminals, would tend to do somewhat the same thing. What I need to know, then, is it ok to simply attach the "super tweeter" w/o additional circuitry across the speaker terminals.
ZD, I missed your last post before I wrote mine. Your comment regarding the use of the EQ to unburden the amp is the kind of creative thinking that most of us would not have envisioned. No, then, I haven't tried that approach.

You asked what I was still lacking and I don't have a good answer except that it just sounds better at moderate volumes. Because that has probably to do with the very nature of how systems work or how sound is perceived, I might simply be expecting too much.

What I'll do at this point is put the EQ and power amp back in the system and see if I can do something with your suggestion on finding and operating within the "sweet spot".

Piezo tweeters usually don't need a crossover- you can just hook them up. Check with the manufacturer to be sure.

You may need some kind of level control to tame its output.
I understand Ultra Tweeters are still available. They produce only very high frequencies, just over 1 GHz. I used to have the Ultras in my system and even had the Deluxe Ultras in the same system.
