These full-range bass cabs with 6" and 8" drivers are intriguing me, mostly because I'm not a huge tweeter guy but I do like high freqs in my sound. But I'm also into keeping all my drivers on axis because the improvement in sound is noticeable. But the cabs in this style that I've seen look like a woofer, a mid driver, and a tweeter stuck in as small a box as possible because it makes the package small, like a 12" in the lower left corner, a 6" in the upper right, and a horn on the upper left. I like small cabs too, but I want a rig to make sense from an acoustic standpoint. Aside from having the dreaded but ubiquitous tweeter, do these types of cabs get it done with regard to comb filtering issues, or are they merely built to utilize cab space efficiently? I've been thinking about what would be a good small tweeterless cab rig that would still deliver full range would be a 15" cab on bottom and an 8" coaxial or a cab with a 10" and 5". Opinions?
