    Would anyone see a problem with porting a sealed face combo amp? I forgot to check the back, but assuming that's closed, would cutting a hole or slot in the bottom of the face do more harm then good?

    I have a new Fender Bassman 150 that is ported. It sounds very good, and projects great as well. Very nice for small band practices in a basement instead of the big stack.

    I'm curious about porting an Ampeg Portbass 2x10. I was checking one out in a store, and it wasn't ported. Just seemed like it should have been.

    If porting would improve it, maybe I'd swap the Bassman for it.
    Thank you.

    Don't do it. Ports aren't just holes, they are designed specifically for the speaker and enclosure. Similarly, a speaker in a sealed box will likely require a significantly different enclosure to be used in a ported configuration.
