Genzler Bass Array Cab Question (I tried searching this question but didn't have much success) The Genzler Bass Array series of cabs have attracted my interest (ie: BA-12-3). Regarding the four 3” drivers that make up the line array element. Are these four speakers in their own enclosure? Or, are they mounted on that front baffle board as four open backed speakers? It’s difficult to tell eggsackly what is going on from the picture.......thanks for any insight on this.
