Electrostatic speakers and low volume resolution

Nobody is suggesting that air molecules are charged at very high frequencies. They do however resonate when immersed in a very high frequency field of the correct frequency. That's how the molecules get jump started, I.e., moving. You can charge the air as it were using ionizers such as the one I sell, but many others, too, you know, like negative ion room purifiers.

Geoffkait, the concept that you're discussing and how this is mechanically acheived is beyond my ability to discuss in any intelligent way. The explanation reminds me of how one lightning bolt prepares an ionized low resistance pathway for the next discharge or, more simplistically, providing lower air resistance to both cars in a drafting scenario. I thank you for this input which I in no way dispute, but I'd have to go back to school on this one.

Bdp, thank you but the issue I describe occurred well before incorporation of the EQ so, even though it's contribution to potential sound degradation described by you and others are valid points, I don't think the equalizer is the culprit in this case. As a matter of fact, based on testing discussed here, the power amp and EQ are temporally out of the system as I write this. As far as the Behringer and it's specific potential shortcomings goes, I tried 2 other brands before settling on the DEQ2496. Anyway, because I'm very happy with my current setup in all respects except for this low volume issue and my feeling is that it finds its primary cause in my personal hearing deficiency, I'm staying with my existing components for now. The bottom line in defense of the EQ, I suppose, is my unequal hearing problems which have no other acceptable solutions.

Roger Modjeski of Music Reference/RAM Labs is making an ESL speaker that is direct-driven, but it's not cheap. He is also a proponent of low-power amps/high-sensitivity loudspeakers.

Perhaps your observation is not true of all electrostatic speakers, certainly not mine. IMO, In a well set up system, Sound Lab electrostatic speakers retain their ability to present an exceptionally full bodied and rich presentation with full resolution at all volume levels. And, my ears are 71 years old!

Actually Roger is a proponent of understanding power requirements as it relates to driving speakers and achievinng adequate listening levels, regardless of the sensitivity of the speaker. I can recall discussing with him a customer of his that uses his low sensitivity ESLs with his 5 watt EM-7 amp and getting adequate volume from them. I learned a lot from that conversation.

You can currently buy a direct drive amp from Roger for use with Acoustat speakers sans their transformers. The amp puts out some serious voltage. For those in the Bay Area Roger has started an electronics school in the Berkeley area. Check it out if you are interested in learning more about the science of this hobby rather than.....
