My new High-quality hybrid ESL loudspeaker

Statics man · 3rd March 2010, 09:23 PM

Excellent hybrid speakers, here's my version. Unique-sounding, and minimum sizes. bandwidth of 35 Hz - 20000 Hz. 90dB sensitivity.

I think those look quite nice. A professionally finished look.

Beautiful job! Got construction pics?

WOW !!

Your speakers are gorgeous! Could you tell us the perf'd stator's hole size, open area & gauge thickness and also the type and thickness of the stator coating?
thanks
Charlie

Really beautiful!

What are the dimensions? Are you happy with off - axis performance?

Beautiful speakers!

What material do you use for the spacers and if not tape - what type of glue did you use?

What's the XO frequency for the bass, and do you find the integration of bass reflex to work with the ESL-panel?

First in the development of this ESL speaker, was tasked to obtain the maximum sensitivity of up to 90 dB with minimum size, so the ESL has dimensions of 1000mm x 180mm. And spacers 1.8mm
Second ease of manufacture, so the speaker has no supports the membrane, thus achieving its low resonance frequency equal to 100Hz.
The stators are made of perforated metal thickness of 1.0mm, transparency 42%. Covered Black PF in two layers.
For insulators used in glass fiber with thickness 1.8mm
But the main thing was to cover the membrane, because it reminds sandwich.
Mylar membrane coated on both sides of high-resistance layer of
Graphite = 5 x 10E8 ohms and above on both sides of layers of nylon 66.
that gives high sensitivity ESL speaker.
with polarization voltage = 3600V for spacers 1.8mm.

Type of glue 88-СА.
Frequency for the bass 35Hz - 250Hz.

Hi Statics Man,

It's really beautiful. How do you measure the efficiency of your speakers to be at 90dB?

Do you use an active or passive crossover?
