Here they are on the web: http://www.klipsch.com/product/product.aspx?cid=24&s=specs Does anyone have any experance or input on these speakers? I am currently running a JBL 10" sub that is a little lacking in bass. Maybe these will help.? I use my HT for mainly movies. I have been using a pair of Klipsch KG 2.5 bookshelfs http://www.klipsch.com/product/product.aspx?cid=145&s=specs as my mains since 1995 and eventhough they still sound great I feel like I might be missing out. Don't know if these SP-1 are the way to go but I think I can get them pretty cheap. Also I will be upgrading to a HK 335 receiver. I have heard that the combination of HK's warmth and Klipsch's horns is a great match.
