Hi, everyone - new to AK but have been lurking for awhile now reading up on the TI chip amps.
I've gotten through a great deal of the TPA 3116 vs the tripaths thread, but I'm not sure if anyone has reported on this TPA3116 mono active subwoofer board:

The left knob adjusts the crossover frequency and the right knob controls the volume.
I've been using this to power a 10" Pioneer dual voice coil car sub that's under my computer desk.
Been running at 2 ohms using a 24V laptop power supply for a couple of months now and it is working great!
I got mine on the bay for less than $15 shipped - here's some more info about it...
Specifications:
Board Size: 55 x 83 x 29mm (not including potentiometers projecting 15mm)
Operating Voltage: DC 12-24V
Frequency Response: input 20Hz-20KHz
Low Pass Crossover: 20Hz-180Hz adjustable
Audio Input Sensitivity: 500mV
Loudspeaker Impedance: 2-8 ohm
Output Power: 19V: 24W (8 ohm) / 48W (4 ohm) / 60W (3 ohm) / 75W (2 ohm)
I went ahead and installed it in a low cost aluminum project box:

In my setup I also have a Breeze Audio TPA3116 running Dayton B652-AIR bookshelf speakers - these really are wonderful sounding little amps!
I think the sub amp was mentioned earlier but I believe you're the first to give it a go. Nice job and thanks for the informative post.
