Cover fits perfect the sub and it has a generous pocket where you can put all cables etc.
Regarding KS 112 is one of the best 12" sub on the market. I would recommend it to all DJs. It is powerful and keeps up with 2 QSC k8. Easy to carry and fits in all cars.
Driver is a regular paper one with 2" VC ... even so it delivers great bass and you feel it in your chest. (StressAudioPro)
