Tas5630 with DSP board for Subwoofer

Hi All,

Currently in the process of designing a ported subwoofer, with true RMS of around 300w. it should be cost effective as well.
Problem is, If i start looking for a driver which gives a good response, is expensive.
So, planning to add a DSP which can be tuned with a USB port! and integrate it with TAS5630 in PBTL mode.

But I lack the knowledge of designing and integrating a DSP with a Sub board.

I know this is an untapped segment. But, this might help me a lot. Guys, who are experts in this, please help me.

Thanks,
