I'm looking for a subwoofer to go with my newly acquired Monitor 70s (with CS2 on its way). I don't feel like paying more for a subwoofer than I did for my main speakers! The price of the PSW505 seems pretty good - but even in this forum it doesn't see to have many supporters. Is it really that bad?! If I don't get that, I was thinking about the cheapest Hsu, the STF-1. But maybe that wouldn't be a good match to the "power" of the monitor 70s?
