Variac, your Basszilla is doomed to complete obsolescence. You are not using a G2Si, which, in another thread the Gooroos have just told me is about the only tweeter worth using for high-xo uses. Suffer. Regret and suffer.
Where you been, man??
I upgraded to the 2si years ago - Dec 2001 to be exact

My woofer is now an obscure JBL 15 " woofer; the 150.
It was only used in (very expensive) complete speaker systems by JBL, not sold as a separate driver. It has a super huge magnet which is why I think its super damped! Sounds super good though..

I'm making party speakers with the Selenium, that will preserve my Basszillas...

Sigh... wish I knew. Can't even remember how I got there.

Tell me everything about the diffs between the JBLs and the Seleniums. Have you put the JBLs in the Basszilla, or are you now using a new woofer box with the JBLs?

Thanks a lot. It was. I read it and passed it on to a couple of friends. It also helped me do some more experiments with Unibox.

Adire Audio made a reference design using the old Shiva subwoofer in a 5 cu.ft box. The frequency response curve drop slowly from 80 Hz to 19 Hz where it's about 5 dB down from 80 Hz. It was done to simulate the room gain curve.

I made a subwoofer with that reference design for a friend and it was measured with a Ratshack meter. It was in fact flat in room (± 1 dB) down to about 16 Hz.

So, I'd say it works perfectly. I'd recommend about 2 dB or 3 dB per octave drop.
