Just curious if they are going to build Dual tubes in the future. I have 2 25-31CS+'s with the Sampson amp and I love them to death. I was thinking of pulling the trigger and buying 2 Ultra's for the living room(or switch the ones in my HT room). What I would really like would be 2 dual ultra's. I have 4 Tempests lying around maybe I'll just build 2 dual sonotubes or something. I'm done rambling feel free to chime in.
