@dastro My first reaction was that that was a heck of a good price for Nautilus 802s. That said, I wonder if the reason the price was so good is that they didn't sound right to the original owner either. I'm with the other posters who say check to make sure everything is working correctly. I've seen reviews where something didn't sound right and it was found that something was wired out of phase inside the speaker. You could easily check that by reversing ONE set of speaker wires to see if the bass gets better.Good idea, I'll check it. But I doubt anything is wrong, the previous owner had them for years and was reluctant to sell.
I should also mention that upon further listening I hear what seems like a graininess in the ultra high frequencies, almost like a background hiss that stops in between songs.(only present when material is playing). It is definitely noticeable, more so now that I picked it up.
At this point my thinking is either this model's sound just isn't for me, it's not playing well with my room's acoustics, or maybe there are crossover issues.
The bass leaness could also be a matter of perception since I find the highs so exaggerated.
