I am using a similar setup: B3n into an active EV ZLX15P. Soundwise I couldn't be happier. Also, for bedroom practice it is great, since it delivers a consistent sound also at low volumes. Just be wary that the wattage of a PA speaker does not compare to the wattage of a dedicated bass rig. Mine is rated at 250W RMS an I have not too much headroom left when playing with two reasonably loud guitars and a reasonably loud drummer. Runs into clip protection fairly quick. Still great for smaller gigs, but don't expect to rock the Estádio da Luz with it. Also, I wouldn't trust the wattage on budget speakers. Maybe @Wilmar Boer can chime in. He has a similar setup.
