You are bidding on a pair of used Techwood S8R Rear Surround Speakers (made by Welton Sound Systems USA). They are ready to be hung on the way or placed on any surface (with non-skid pads). There is no power rating specified on the unit, but it's heavy duty with solidly built (unlike some chepo surround speakers with small magnets and light weight). Excellent working condition! Measures approx 4.5"x7"x4". I also have Techwood bookshelf speakers SAT62 for sale, please email for more info, thanks!
