I'm looking for a sealed 15" box to use for bar/small room gigs with a Fender Bassman 100T. I want something around 400 watts. At the moment it looks like a Bergantino NV115, if the budget can stand it. The only other one I've seen is an Ampeg, I forget the model, which might be the one dictated by finances. Do any other companies make 400 watt sealed 15? And yes I am after the particular frequency response of a sealed box.
