I like the subway 15 cabs , and most gigs I do especially with PA support one cab is enough. It sounds great and I’ve gotten compliments from a few other bass players about it. Haven’t tried the 10s though, but I could see a 210 being interesting.
I’ve been using double 115 setup for years, but I’ve wondered about trying a 2x12 to be louder than 1x15 but shorter/lighter than 2x15. I wish the 212 had the tiltback wheels like the 2x15 though. My drummer prefers when I only bring 115 on a gig though.
