Newegg offers two Pioneer 4" 2-Way Bookshelf Speakers
, model no. SP-BS21-LR, for $49.99
for shipping. That's $50 off and the lowest total price we could find, although we saw them for $11 less (after rebate) last month. These speakers feature 80 watts RMS power handling, a 4" woofer, and 1" soft dome tweeter.
