JBL SRX700
For over a decade, JBL SR and SRX series speakers have represented the best performance, highest quality and most advanced driver technology available to portable PA users. The SRX700 series continues that tradition and moves the bar even higher.

The advanced technology of SRX700 series speakers delivers the power and performance that you would expect from the highest quality, professional rig. At the same time, JBL innovation and design have reduced system weight so load in and out are a breeze. All this performance is housed in rugged birch enclosures for years of superb performance.

JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
