Kinda of a late response, but I have a pair of RF-3 towers paired with a diy subwoofer, and absolutely love the results. My setup is an Alpine Type R 15" (SWR-1522d) and a dayton SPA-1000 950watt amplifier. Setup was about $550 (if you find a deal on the woofer online) +cost of mdf. Output response is very flat, sails way past 120db, and completely has its way with my 19x14 listening space. The apline woofer sounds fantastic, and since it cools so well, it can be played near the limit for extended periods without breaking a sweat. Originally I had used the Dayton RSS-390HO, it too performed pretty well, but the the coil wasn't up to the task apparently. The setup blends seamlessly into the system with the RF-3.
