Here is another option if you are looking for an unconventional way to drive a system to great power for less $.

Prbably a better result by definition. Powered Studio monitors. I've seen it done before by Ethan Winer of Realtraps. I've heard the 5" models and they play very loud and clean, and suprisingly low. The 8" models would not require a sub at all. RCA cables from Pre-outs and good to go.
