Newegg offers the refurbished Logitech Z506 Surround Sound Speaker system for $39.99 with coupon code EMCPCGW85 at checkout. When compared to units in new condition, today’s deal is $60 below Logitech’s current asking price and $21 better than Amazon. It’s also the lowest refurbished price we could find by $10.
This setup includes four satellite speakers and one ported, down-firing subwoofer with support for game consoles (PS2/PS3/Xbox 360, etc), TVs, DVD players, computers, and other audio sources. It packs 75 watts of total power, which Logitech claims is enough “to fill the room with sound—and even rattle a few windows.”
Over 700 Amazon reviewers rate it 4 out of 5 stars.
