Seas L21 designs?

Spasticteapot · 31st July 2008, 07:31 PM

Does anyone have any recommendations for the use of the Seas L21RNX/P woofer? I have not seen many people using it, and most of the designs are barely capable of a -3db point of 60hz.

Hi,

Its now an "old" driver, around 25L sealed and 40L to 50L tuned
to ~ 26Hz seems about right. The latest version is barely different
in real boxes, H1252-8, L22RNX/P.

I'd triangulate the oversized midrange section to something more sensible,
and add that volume to the bass section, keeping overall dimensions.
