First of all at 15kg this cab is insanely light, I can easily carry it with one hand and my Markbass combo amp in the other hand.
Secondly, the sound is very pure, but a little harsh, which I think is typical of 2x10 cabs. It has a dial for the tweeter, but I couldn't hear any difference between the maximum and minimum settings.
Thirdly it is rated 400W and it can go very loud. It vibrated my drink off the shelf it was sitting on just above the amp.
Fourthly, it can sit vertically or horizontally, and is very stable. The plastic corner pieces lock in with other Markbass cabs and amps. When it's vertical it's nice and high, nearer your ears when you are playing on a small stage, and it saves space on a small stage in that position too.
It looks tough, I'm sure it will last for years, although the grill is a bit "bouncy", which makes getting controlled feedback out of it via pressing the bass against the grill a bit tricky. I'm use to Trace Elliott sturdiness.
It has two Speakon sockets, so you can run it in series.
The only drawback is that it only has a carry handle at one end, which sometimes can make it a bit unwieldy to move around, although it is very light and only needs to be carried one-handed.
