For sale is the Celestion Trinity 2.1 Speaker setup. Can definitely discuss a much lower price for all, or only some, of the speakers. http://www.hifi-classic.net/review/celestion-trinity-525.html 1. This is the Celestion 1 bookshelf speaker(s) plus the Celestion 135 Passive Subwoofer. In great condition. Can be auditioned. $100 for both. The Celestion 135 Passive Subwoofer is designed to work with the Celestion 1 and produces a very impressive soundstage. Does not require an amp with a sub-out. I will sell the Subwoofer separately. 2. I also have a Celestion CC1 (not pictured) Center Speaker with a tiny dent in the woofer's dust-cap for an extra $20.
