So I've got this Marshall head that puts out something like 200W at 4 ohms, but it's here, and it sounds good (and them are loud 80's watts). I'd like to build a neo cabinet, and I'm comfortable with many of the concerns about building cabinets/speakers. I miss (the sound of, not the weight of) my old Mesa RR215 a bit as well. So, I'm thinking about a 215+mid or 212+mid, but the fEarful Kappalite cabinets seem like a bit of a waste, because I'm not going to use anything like the available power handling. In the past, I've enjoyed the aforementioned MESA, a couple of ACME Low B's, and some other cabs, while thinking the Bag End 410 was a bit thin on the bottom. I don't need extreme lows, but I don't want the boink-only-nothing-below-80 sound some cabinets seem to produce. I do need to sacrifice some real bottom for efficiency. What do YOU guys think is going to give me the most efficiency at this relatively low wattage? Build a Deltalite 215 with a mid? Scrap it and build a BFM 212? (I'm not enamored of the idea of EQ'ing back in some lows, especially as the Marshall has really strange EQ points) Omni 15? I'm drawn to a 4 ohm, 2 woofer direct radiator with a mid, for completely illogical reasons, but I don't want to shoot myself in the foot just for that.
