yes there is but there is only one im not really looking to buy it and seat on it for a year trying to find matching ones... id even be happy with 4 9515's or btl 15's
Finding 4 of either will be hard to do.I had to buy motors,and build them up to get my DD 9518's. May look into AudioQue HDC's if you are in a hurry.(and the prices are not too bad).
