Anyone know of a good subwoofer to match with the orb audio MOD2's for around $200? I sold my orbs to a friend and replaced them with bigger speakers. I had an old 75 watt Yamaha sub that I gave him, but he wants something a little better without spending too much. It would also have to extend up to 150hz as that is the crossover for the orbs. I was thinking maybe that new Pioneer 8" Pioneer subwoofer from the Andrew Jones line.
