The driver for the Parts Express sub kit looks a little weak - better to use this one? http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-420 Then of course you're going to need one of these too! http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=300-806 This one actually has a tighter sound to it. http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-468 I have the one you mentioned. Great driver and a fantastic kit. But the High Fidelity is a little better in the sound quality. It would also match better with the amp used.
