Small musical sub for PMC GB1i 2 channel system?

Any recommendations for a small musical sub to go with a GB1i speaker 2.1 system?


Have a look at the Rel T5 or T7.
I am not familiar with your speakers, but I find the compact and relatively inexpensive Glow SW1 really musical and fast enough to keep up with my Hempconed Omega A8's. When dialed in right, the bottom end is filled seamlessly.
