I have a pair of TC2+ 12's that are SVC 4's. I'm letting them go for $100 shipped each. Covers shipping and paypal fees! Or $80 + shipping, whichever is cheapest for you!
Best subs you'll get for $80, end of story! SQ is amazing and they can handle up to 600 wts each. Get plenty low and loud also!
I've got a pair of Directed Audio Studio 12s, 4-ohm DVCs (4- or 1-ohm final load), 750RMS each. They're great subs, I used 'em for a couple years, I'll sell 'em for $125+ actual shipping. Solid subs, I liked 'em alot. Great output, good SQ in a sealed 1.2 cube per sub sealed box.
