i'm really curious how electric bass sounds through a cab with small drivers like 8's. i'm thinking about getting one since i'm most likely going to be doubling on electric and upright bass, so i'm thinking the quicker response of the smaller driver would be ideal, but how about the low end reproduction? is it adequate with just four or six 8's? what about a ported or sealed enclosure it seems a port would help with low end? is there any kind of cab that is sealed anymore, seems all are ported. this would be powered by 275w @ 8ohms or 400w @4ohms. i'm thinking i might just order an avatar 2x12 and hope for the best, also looked at the acme cabs too, seem pretty sweet too.
