Why 15"s for bass?

Why have bassists stopped using 15" bass drivers? We haven't made a 15" bass cab in a LONG time, but with the advent of the Upsizing 212BB, we've been experimenting with 15" bass drivers in our cabs (we also fell in love with the Fullback, Celestion's main 15" guitar driver, in a recent video:    • "This sounds like a 4x12 should" - Upsizin...  ) We believe that there could be a place for them in certain bassist's repertoire. Do you want to be the one to break the duck and commission a new Barefaced 15" bass cab? Drop us a comment/shoot us an e-mail!
