As one of its daily deals, Newegg offers the Pioneer 100-watt 8" Powered Subwoofer in Black, model no. SW-8, for $77 with free shipping. That's the lowest total price we could find by $25 and the lowest non-rebate price we've seen. (We saw one for $7 less after rebate in February.) This Andrew Jones-designed subwoofer features a 38Hz to 150kHz frequency response, built-in 100-watt amplification, and bass-reflex enclosure. Deal ends today.
