I bought this cabinet along with the TC Electronic BAM200 amp head to replace my Markbass Micromark 801. I needed something a bit more powerful, but not too much bigger. For the price, the cabinet is surprisingly well built and feels very solid. It's quite lightweight and the form factor makes it easy to carry. However, I'm not so sure about sound quality. I confess I didn't look at the frequency response, but with a 70hz-4000hz freq response, one shouldn't expect hi-fi sound. Compared to the MK bass, it somehow lacks clarity and definition in the medium and it doesn't reach as low. What you mostly hear are low-mids and some higher mids (trebles, as expected, are shy without any tweeter being used). It certainly does produce a "beefier" sound than the MK801, but I don't like the tonal qualities, whatever equalization I do. A couple of days later, I heard the MK bass Minimark 802, which also uses 2x8" configuration, but with an additional tweeter, and the sound was in another league, imo.
So I guess it depends on what you're after. It does sound decent and it's well made, but don't expect miracles. So back it goes. Thomann's service is great as usual :)
