Newegg offers the refurbished Pioneer Andrew Jones-Designed 2.1-Channel Soundbar System, model no. SP-SB23W/B, for $154.99 with free shipping. That's tied with our refurb mention from last summer as the best price we've see for this system. (It's a current low by $76.) It features a 6.5" 2.4GHz 50-watt wireless subwoofer, six 28-watt speakers, four 3" mid-woofers, two 1" dome tweeters, Bluetooth, and frequency response of 45Hz to 20kHz.
A 90-day warranty applies, but it's unclear who backs it.
