Adorama offers the Polk Audio TSx 330T 2-Way Floorstanding Tower Speaker in Black or Cherry for $89.99 with free shipping. That's $5 under our September mention's per-unit price of two speakers and the lowest price we've seen. (It's also the best deal we could find today by $30.) It features a frequency response of 33Hz to 25kHz, gold-plated 5-way binding posts, and 8-ohm impedance.
