Here is what I and many consider the *best* sounding, loudest, easiest to transport, no need for an 810, all in one bass cab ever made !! This is the Mesa ( M6 Carbine) 212 600w bass cab. Let me start by saying 600w is a conservative rating. If you know how ridiculously LOUD the M6 Carbine is to begin with, then you know this is the real deal, as well. This cab can handle the Mesa M6 Carbine effortlessly. It was made to pair with that head, but ANY 2 space head will be at home here. I have used an SWR Bass 350 through this and it was magic !! This cab will handle most ANY room. From small bars, to large auditoriums seating 3,000 people, this cab will fill the air easily. No more carrying around a set of 410's or a fridge. This has a small footprint, and will fit in the back seat of most 4 door cars. The newest Mesa crossover system is on the back of the cab, so you can tailor your speaker tone. Also, there are three vents. One on each side and the top, so feel confident that your amp has a lot of breathing room. Overall, it's in excellent condition EXCEPT for the bar is bent. No biggie. A cab fell on it, and it protected the amp ! Look at it as a dual purpose bar. Also, I am including a brand new Mesa cover for it !!! I get phone alerts when I receive a PM. $550 SHIPPED !!!!! That's $425 for the cab plus shipping ! It's a total deal !
