Trying to build dipole sub - a la Celestion 6000

Hi,

I always love electrostatic panels and I also love the bass that I've heard from celestion 6000 subs. I have a pair of innersound and Sander Sound electro stats and now I would like to build a pair of bass units like that of the celestion 6000. If anyone has any insight on this; I would love to hear it.

Here's a link to some info on the Celestion...

However, you may want to look for some form of equalization for the 6 dB rolloff, perhaps DSP. There's Digmoda that has built-in DSP on their plate amps but, of course, plate amps aren't all that convenient for dipoles.

Siegfried Linkwitz has written extensively on dipoles. Read his web site.

Analog solutions to the dipole roll-off and sub-woofer cross-over are simple and are possible in passive line level form if you have enough gain in your preamp + amplifier.

Note SL's Phoenix prototypes page which has an H-frame with passive dipole equalization and LR2 cross-over to the main speakers.

Also note his active filter cookbook

Enjoy!

Should add that Madisound offers a service to precision cut the wood.

For this purpose, there are some pro amps that offer gain control, delay, crossovers and DSP along with gobs of advertised power for between $500 and $1000. Crown XTi series, Peavey, Powersoft, etc... Even saw that one had RCA's.
