It cost me no more than $50 plus woofer.

Re: Titan 48 (OSB panel), Beyma Power15, GDN-38-550-8-AE

I disassembled my Beyma Power 15 from aperiodic enclosure (5 cu. ft), put in Titan48 and forgot remove low pass filter. In comparison to closed box bass is more felt on body but this is ca. 70Hz not 40-50Hz :) We'll see on Monday. It vibrates quite a lot ;)

I sealed internal walls and covered OSB with felt. Impedance has changed as you can see because I removed 6mH coil.

Ok. maybe not light but certainly a lot cheaper to experiment :D - I wanted to see how my drivers behave.

Simulation. Impedance of real speakers is shifted toward lower frequencies.

True - I wanted to have something light and quick on New Years Eve. 40Hz dip is too strong compared to your samples?

Titan 48 (OSB panel), Beyma Power15, GDN-38-550-8-AE

This is my Titan 48:

driven with Beyma Power 15 and GDN-38-550-8-AE (Qt=0.9). Do you see air leaks on impedance plot?
