Will this combination work? Does running a 100W vintage head completely defeat the purpose of using a power hungry, modern cabinet? How about the V4B into two GS112s? I've read it can be dangerous to underpower speakers. Maybe this is a ridiculous combination. I'm relatively ignorant when it comes to bass amplification. Basically I love the sound and portability of the GS112 and may have access to a V4B, which I dig as well. There's no way a folded horn 2x15" cabinet will fit into my hatchback.
