Best speaker new or used 2,000 for ROCK?

Speakers will be run from B&K AVR 202 which has 105 watts per channel. Will also be run with two Velodyne HGS-10 subs. I do venture once and awhile toward more docile music, so a versitile speaker would be ideal. I just don't want to end up with a speaker that is not well equipped to handle the type of music I listen to most of the time. Finally, any bi-wire cable recommendations? Thank you.
