I'm going to chime in with one last post. DON'T believe manufacturers specs. If it is a ported design, it will have trouble going below 40hz ( not to say it can't but usually they will be very expensive). Manufacturers spec speakers with all kinds of figures and most are baloney. Your room also has a lot to do with this. I guess what I'm trying to say here is I've never seen a speaker in that price range REALLY go down that low. For example, the B&W 805 Nautilus was spec'd to go fairly low (less than 50hz). In my room, the best it would do using a spectrum analyzer was about 56hz at -6db. It dropped off like a rock after that. Most speakers in your specified price range are going to be ported as I've said before. At that price range, they will have a bump in frequency at about 60-100hz to allow them to produce much at 40hz. Pull out some old Stereophile magazines and check it out.
I would go with an accurate speaker such as the Vandersteen with a genuine low end. Any ported speaker is a hard match with a sub because of the phase shifts around the crossover. A sealed design matches better with a sub.
By the way, B&W makes several lower cost subs that I would think would match up reasonably well with your 602's. Try before you buy is my best advise.
I'm of the accuracy school. It is the primary reason I use Vandersteen loudspeakers. They are accurate. I also believe in phase correct and time aligned designs. You get a lot for your money with Vandersteen because the box ain't much. He doesn't waste money on a lot of wood veneers.
I was in your position some years ago. It is a learning process. I used ported designs for a while and I will never go back. But, the biggest thing is to satisfy yourself. Listen with your own ears and make your own decision. Nobody can do it for you. Good luck with your hunt.
