I`ve just got a Techwood 42 inch Plasma tv, and the tunner box has a Subwoofer line out,so i`m after a subwoofer to go with the speaker`s that go in to the tunner box that go with the plasma tv, the speaker`s are 12 watts and 8( is it om ?) each. it say`s Audio Output Power (w rms) (%10 THD) STEREO 2X14. Just want to no what`s the best sub, to go with the speaker`s i`ve got with the plasma tv, to go into the tunner box. Thank`s Marcus.
