You know the names and the companies. Now own the sub. Asking $500 plus shipping for the combo. Will include a 18' (rough guesstimate) speaker cable and a male RCA to female XLR cable to connect the sub from your receiver to the amp. The sub has the ISD driver and is 2 years old. The amp is 3 years old. I will sell them separately for $350 for the sub and $225 for the amp. Best figures to use to calculate shipping: Sub: 20" W x 20.5" D x 44" H, 60 lbs. Amp: 24" W x 20" D x 8" H, 50 lbs.
