Does the PB13-Ultra ever go on sale or have free shipping? Thanks.

I saw one at perfect mounts that might fit the bill (4") but was wondering if anyone knew a different one that might be better. Epson 6100

Hello Shack; I would like to know why so many people use this amp for their subs??:dontknow: :scratch: I am an live sound audio engineer by trade and I have found them to be harsh and unreliable on the road. They may work better in an HT environment and as a sub only amp. I have never used them...

any one help? very appreciate:sweat:
