Hi, this is for a pair of KLIPSCH SYNERGY S-1 Speakers, 50 watts 200 peak with a 4" driver and two .3/4" tweeters. These can be used as a front left, right or center channel speaker. and of course these are for rear surround use. These will add extra high frequencies to your listening because of the 2 tweeters. The speakers cabinets and grills are physically in excellent condition and could look new. They work and sound great as they should very detail.
I also have 3 of these exact speakers on another posting but in a slightly bigger, 100 watts with a 5.25" driver and two 1" tweeters . The model is Klipsch Synergy S2. Feel free to ask any questions and thank you for looking :-)
