Thx Pete for all the help, and yes the Atlas is working now. I don't fully understand the prob, but I think it was a combination of a lot of little things (i.e. Phase adjustment, Equalizer on my reciever, and just breaking in the speaker if that makes sense - seems that the more I play the sub the better it gets).
I'd really appreciate any help you can provide, I'll send you an email replying to your post.
