Amazon offers the Infinity Primus 3-Way Floorstanding Speaker, model no. P363, for $99.95 with free shipping. That's the lowest total price we could find by $100, although we saw it for a buck less last month. It stands 39" tall and features a 3/4" dome tweeter, 4" midrange driver, 6.5" low-frequency drivers, frequency response of 38Hz to 20kHz, and crossover networks.
