Awesome Passive Sub

March 20, 2014

Man this was exactly what I was looking for in a passive sub. I'm a JBL guy by heart but I was looking for a passive subwoofer in bandpass enclosure for outside gigs. This was exactly what I was looking for.....I was prepared to swap the woofer out in it if needed but it proved to me that this was not needed. This setup really rocked with a Alto SX on top of each SUB18. I chose to drive each enclose with it's own Crown XLS2500 amplifier. If your looking for a passive 18" subwoofer look no further.
