This is a pair of lightly-used Definitive Technology ProMonitor 800 Satelite Speakers. They work great for home-theater or in a small stereo setup. I've found they produce very good sound and surprising bass for their size/price. I recently upgraded to some higher-end speakers for my desktop stereo setup and no longer need these. Price for the pair of speakers is $200 or-best-offer (cash only please). Avaialbe for pickup in the Layton/Kaysville, Utah area (18+ years of age or accompanied by an adult, please). Please message on KSL or text me if you have any questions, or would like to purchase the speakers. Thanks for looking!
