the BIC towers I could find have a shipping weight of 40 pounds, so they would probably run about 35 out of the box. They have two active woofers, two passives, and a small tweeter.

To give a comparison, my Infinity Alpha 50's weigh about 55 pounds with a tweeter, mid, and two woofers. I wouldn't worry too much about the weight, as long as they are not directly next to a wall and you have a decent sub.
I've read alot of good things about the BIC products and they seem to be one of the better affordable speakers currently on the market.
Another decent choice is the Athena speakers, which BestBuy seems to be in a hurry to get rid of. You can get the tower FS-1's from their website for $ 97 each and the surrounds for less than $ 80 a pair. They claim to be sold out on the center channels, but you might find one at your local store.
