First off I know this is not the best sub setup for home theater, but the fact is I have this stuff laying around plus the rest of my "home theater" is nowhere near the best stuff. I think it would sound better than buying a $100-200 powered HT sub. I have 2 12" 8ohm rockford fosgate subs and a harmon kardon HK-3480. The reciever is rated at 120wx2 @8ohms. Here are the sub specs:
I know how to build boxes for cars, and I gather that HT subs are just tuned more for flatter response and lower extension, correct? What size and type of box should I be aiming for for these subs? I'm thinking that both channels of the reciever must be connected for either of them to work, so I can't go with just one of them(not even sure I want to). Would seperate boxes on either side of the towers be good, or one big box perhaps built into a stand for the TV, and if one box should the woofers be divided or in a common chamber? Do I get an RCA splitter to hook up the sub out to the 2 RCAs on the reciever? Do I need a seperate crossover or will the sub out on my main receiver do that already?
