If you think that Jews on Christmas only abuse Chinese food and watch endless movies then think again. Since obnoxious stolen Christians my beloved Christmas tree a few years back some of the Jews torture compression drivers during Christmas’ everything is closed.

What I did was figuring out I might to use my Vitavox lower then it is. I removed the phase plug from the driver and opened up back chamber.  The diaphragm I used was with plastic clear surround (not white surround). The free air resonance dropped to 320Hz, I estimate that in the horn it will be around 250Hz but I did not measure it. What I did measure is response from listening position:

It is already something and horn do begin to demonstrate some sighs of overloading with bass, but not the type of the overloading that I would like to hear. If we set reference point at this response at 84dB then -3db will be at 300Hz. Not bad but I would like to have something different. Instead of having 2dB peak at the bottom I would like the driver to be flat in there but to go another 70-100Hz lower. I do not think this driver would do it….
