Quasar Mk2 Filter (BD-Design)

Hi Bert,

I am building something which resembles the Quasar. Supravox 215 wideband, Lambda td15s woofer. I am trying to actively equalize the dipole rolloff of the woofer. I was wondering. Is the filter you use on the Quasar Mk2 composed of two first order filter in series (a bit like the one for the Oris bass but with different values)?
The reason why I am asking is that Linkwitz uses a shelving low pass for dipole equalization. Now I think my lambdas are closer to your BD15 in terms of frequency extension and may do away with a simple first order filter at 20hz for dipole equalization rather than a shelving low pass.

TIA.

Best
Giulio
