Here’s a possibility:
Dayton Audio RSS265HF-8 10″ Reference HF Subwoofer 8 Ohm from Parts Express and Yung SD300-6 300W Class D Subwoofer Plate Amplifier Module with 6dB at 30 Hz, also from Parts Express. Here’s an optimized box.
Maybe make a reading bench out of it?
The 3″ port was just a quick eyeball measure to keep velocity down. Smaller ports will be shorter, just be realistic with the amount of air the woofer can move.
