The LFM1 will give you the output capability of two UFW-10s. It will also go lower. One UFW-10 will not cut it for home theater: it just doesn't have enough piston area for high output. That said, it does provide very tight bass that works well for music. For output and extension, the SVS (I assume you mean the 20-39 pci?) will easily better the Rocket and would be on par with the LFM-1, though it will go lower. If you can put up with the water heat look, it's a good sub. I thought WAF was important?????
