I don't know how motivated Bobby is to design a sub. There are already some excellent choices out there that blend well. My TSM's are currently running with an MJ Acoustics 150, which is a small sealed 10" with a remote. The remote and digital displays make the sub very easy to tune, even on the fly when tweaking for specific recordings. Sadly at around 1800.00 I wouldn't call it a bargain.
Sub is set to 47 hz roll-off.
