I can remember reading an article in the Dutch Elektuur magazine somewhere in the early '90s describing a project using a piezo tweeter with added weight mounted to a woofer cone to couple the actual woofer output back to the amplifier and as such compensate any non-linear behaviour etc.

Does anybody still have that Elektuur? I'd be very interested in having a copy of that article, I'd even go as far as to pay any postage fees.

Best regards,

I have this article and I have also started a project.... long time ago. With a 5" wideband speaker it worked pretty good and the real object was 12" Sinus (Sweden) woofer. Unfortunately the project went cold.
