Bert’s subs with back-loaded horns (BD-Design)

The BD15s also reward improvements in the amplifier that drives them, even
when used just for low frequencies. I use the Sugden A21 Class A
amplifier.

Nice to hear I'm not alone
I run subs with BD30-like amps (chip amp with quality PSU). Surprisingly good! :yes: I respect Sugden A21. Not cheap though .

What filter parameters have you end up with? (I mean R & C values)

Regards,
Dmitry
