My computer speakers at home are Lacie Sound 2. It cost me a mere $136 and I'm very satisfied with it. It looks and sounds expensive. The bass doesn't sound silly and flabby like how I've experienced the bass from PC speakers to sound like. In fact it booms with just enough intensity, not too much, just enough to get my groove on. The speakers sound very balanced, crystal clear and I love spending countless hours with all my favorite tracks playing through it.
I think nowadays you can get pretty worthy PC speakers at more affordable prices, but I guess it all depends on what you're using them for and how much you're willing to fork out for them.
For the higher range products in the market, I was really attracted to B&W MM-1's sound when I saw and heard it playing at one of the stores in my area. It 'punched' me, literally. I felt out of breath. It is small too, I never expected the punchy sounds I was hearing came from this dwarf. Soon!
