hi ht'ers. im selling my infinity hps 1000. this sub has been very well reviewed. the sub has a 15 inch driver with 2 15 inch passive radiators. amplification for the sub is provided by a 1,000 watt amp section. becuase the sub weighs about a 100 pounds id like to not ship it therefore id prefer a local butyer. im in southern ca. for pics follow my signature link. this sub reatailed for approx. $1300 -1400.im asking $550. the average closing price on ebay for this same sub has definately been higher than my asking price. p.s i have an ebay rating of +35, and know several ht forum members persaonlly so you can be assured that the sub will perform as promised and be in excellent condition as described.
