Depends on the price, your roo layout and where you have been as far as speakers. I owned a pair about three years ago and put BP10's in back. Bipolars need room to take advantage of the design. Ideally about 2-3 ft in back and sides. If you can pick them up for about 30-35% off list you can't beat the bottom end for the price and they will blossom. They have their qualities and their limitaions in regards to accuracy but do offer a bang for that buck if you can accomodate placement.
