Here is my story. I have had a PW2100 for a couple of months now and I have been tinkering with it more and more. Originally I calibrated it using DVE and found the sub level to be a little quiet. So I upped the gain on the amp a little and everything was to my liking. So one day I was listening to some 2 channel music and I wanted to boost the low end so I cranked up the level to about half and enjoyed. I got up and left and forgot about the level sitting at half. That evening my buddy came over and I popped in Star Wars AOTC to give him a demo. I turned it up and as the driver slammed into the back of the sub I remembered how hot I had the level on the amp! The inability of my beloved PW2100 to play low end frequencies after that had me taking it in to my dealer to service a blown driver. So here I am three weeks later waiting. I hope my misfortune has entertained you a little and I want to ask a question. How do you safeguard against this type of thing? If I didn't know any better I could have set the level to half when I first set up my system and then watched my sub explode without knowing any better. I know all you SVS guys are going to give me a hard time about my sub being wimpy but it is a great buy here in Canada! It would be nice if it had something that protected it in the event of a damaging signal. I know I'm going to be paranoid for a little while when I get her back. I guess setting the level to half for DVDs is pretty insane loud anyway so that should keep me safe!
