I replaced my EPI UL2 410 with the older Big Baby T. The Big Baby T is not claimed to be as " loud" as a good 410, but at the volume I could hear the UL2 start to compress in the low end, the Big Baby T doesn't. I don't think the claims are far away. I'm currently waiting on a Big Baby2, even smaller, lighter and reputedly louder, we'll see. My first Barefaced cab, a Midget T, which i still have and gig, knocked the stuffing out my EA NL210. For me these are brilliant cabs.
