matrix 803's.. i have chance to buy... worth it?

My dad uses the Matrix 803 s2's. I haven't heard them in a HT setup, but from their performance in a stereo setup, I'd imagine they'd be a great choice. The price is good for either model, but a real nice price for the S2.

I should add that when comparing the Matrix 803 s2 to the Nautilus and Diamonds, I've actually preferred the Matrix and Nautilus. I've found the entire Diamond line to be a little too bright for my taste. The Matrix series has plenty of punch and and the tonal balance is pleasing. Essentially, I've found them to have plenty of detail without being fatiguing. The Nautilus is somewhere in the middle, so if your preference leans toward the ultra-detailed and you don't get fatigued easily, maybe you'd prefer them; however, you'll pay a bigger chunk of cash for a speaker that you might not prefer.
