Newegg offers the refurbished Samsung 120-watt 2.1-Channel AirTrack Soundbar, model no. HW-E350/ZA, for $77.99 with free shipping. That's $2 under our mention from three weeks ago and the lowest total price we've seen for this sounbar. (It's also a current price low for a refurb by $22, outside of the price below.) The soundbar features two 30-watt speakers, a 60-watt built-in subwoofer, 20Hz to 20kHz frequency response, and HDMI passthrough. It comes with a remote control and wall mount. A 90-day warranty is applied, although it's unclear who backs it.
