A couple of questions. (1) Piranha as opposed to Neo speakers correct? (2) What kind of condition are the cabs in and (3) do you know the ohm ratings for the two cabs used in tandem? PJB has some strange ohm ratings.
I'm tempted to get them both and just use what remains of the 6T/9B system (the 6T) for practice at home. 200 miles wouldn't get you to Minneapolis, but since its 401 mile between you and me we might be able to arrange to meet halfway.
