I bought these as interim speakers (I didn't want to spend a lot on a system I knew I was going to replace) & they have performed beyond my wildest expectations. They're loud, clear, punchy, & produce enough bass to pi$$ off the neighbors without the sub (even though I have two of them.) I usually unplug the two SP-FS52 speakers & the two SW8-MK2 subs & just use four of the bookshelves & the center channel for a 5.0 setup so I can still get my Home Theater fix without pi$$ing off the neighbors (I own a townhome.) If you're not an audiophile, do yourself a favor & pick these up. If you don't like them, you can always return them after a few weeks.
