Itching to build a bigger cab this winter, but can't decide which direction to go, so I thought I'd ask the TB hive mind. This cab would be for a rock setting, sometimes in drop C territory. P and J basses with various amounts of dirt, etc. Looking for a single-schlep, 4 ohm, 50 lbs or under ideally, tall cab that can hang with a hard hitting drummer. It'd be nice to have a bit of sound spread to the side for drummer monitoring. Must fit in a standard sedan. Would use 1/2" ply w/ bracing, etc. Cost isn't a huge deal (buy once, cry once). Looking at the following formats: 4 x 12PR300, sealed 2 x Delta Pro 15A, sealed 2 x 15PR400, ported Obviously the ported 2 x 15PR400 could crush the others volume and low en, and maybe that's the no-brainer. But a compact, 2 x Bag End-esque or 4x12 tower have their own appeal and should still meet my SPL requirements.
