STX835
Dual 15" Slot-Loaded Three-Way Speaker
Professional Series
Key Features:
Premium passive loudspeaker system Very high power handling Two 380 mm (15 in) Vented Gap Cooled™ low-frequency drivers, in slot-loaded LF configuration CMCD™ Cone Midrange Compression Driver™ provides low midrange distortion, increased sensitivity, extended bandwidth and improved phase coherence. 60° x 40° coverage. Bi-amplified or full-range passive operation. Twelve M10 suspension points
Applications
Reinforcement of vocal and instrumental music requiring low frequency extension Dance music playback The STX835 combines the performance of a subwoofer-equipped system with single-enclosure ease of use. The dual slot-loaded 2226H 360 mm (15 in) patented Vented Gap Cooled™ woofers deliver impressive low-frequency extension without a sub. The mid-range is covered by JBL’s patented CMCD™ Cone Midrange Compression Driver™ technology using a 2169H 203 mm (8 in) driver. The CMCD design provides very low midrange distortion, increased sensitivity, extended bandwidth and improved phase coherence. The multiband, Progressive Transition waveguide assembly also hosts a 75 mm (3 in) voice coil 2432H compression driver. For applications requiring suspension, the enclosure is fitted with twelve M10 suspension points. The enclosure is constructed of top quality birch/poplar laminate plywood and coated in JBL’s rugged DuraFlex™ finish. The attractive CNC-machined, 14-gauge steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the box to create acoustical interference. The grilles are internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance.

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.
