I was wondering if anyone could provide a schematic diagram for the above mentioned Sub?

I'm looking at changing the drive unit and box specifications and would like to adjust the electronics to extend the output to below 30Hz.

Any ideas? the original filter cutoff was 45hz. However, after modifications, I managed to get the filter down to 35hz. I want to drop it down to 25hz. The filter is based around a TL084 op-amp. What components would determine the low frequency cut off point? I've added an extra pot which allows me to modify the Q factor. And increased the value of some polyester capacitors within the main filter circuit. However, only reduncing the cutoff by approx 10hz. The DC blocking capacitors are 4.7uf. Would I need to increase those in value?

Any help, or links would be greatly appreciated.
