SD315A-88 subs I'm willing to drive within reason (1-2hrs away) to meet up. $250 for all 4 with the enclosures. $350 for all if you want the a 750 watt amp with them. The amp is basically brand new. Please see pictures for subwoofer specs. These subs will play the lowest frequencies you need for any movie and will start rattling things across the house. I had them wired to 4ohm and barely put any power to them since I lived in an apartment. I paid over $900 for all 4 subs, boxes, amp, and bars. Moved into a house with my wife and she says they take up too much space.
