I hate to bump a thread that I put in the wrong section but I feel I need to spread the word about Rythmik and it's owner, Brian. Basically Brian has given me the best customer service I have ever experienced. If you guys are in the market for a >$2000 sub at least put Rythmik on your short list. This sub exceeds my expectations every time I use it. Please feel free to ask me any questions if you are considering Rythmik. Now it's time to upgrade to a newer Klipsch Reference 7.1.
