I would have to agree. You at least like your old sub. At best you will get your old 8" driver up and running. IMHO there is no 8" subwoofer driver.Use your time wisely and hunt down all the threads you can about used subs.For 800.00 you can get an old Velodyne that will change how you watch movies forever. For 300.00 you can get a used Energy 12" sub from Audiogon.com. There are many choices here and not to be rude it's not going back to an 8" sub.
