I use this cab with an Ampeg pf800 head and a Sandberg California TT passive bass only for rehearsals for the time. I have played very loud with it and I have played smooth also (I got it last week). I have played rock, blues, sludge, punk and funk with it in a band and it responded very good through all those genres.
Pros
-The portability of the cab is an awesome feature: the flip-top and the wheels, which you can put on and off with a "click"
-The sound has great low end, though it remains punchy and you can hear clearly the treble and mid notes within the mix. It treats frequencies in a way so you can feel and hear the bass always through the mix.
Cons
-The only con that I can think of is that this cab is a perfect match for the ampeg pf amp heads and many of the features that it has would go to waste if combined with other amp heads.
(keep in mind that I play this cab with the pf800, so i guess that I could have a diferent point of view if I played with another amp head)
So, in conclusion: The cab's perfect match is a pf head. Great portability, it cuts through the mix , it's got great low end, it is punchy and it treats mid and treble notes just as good.
