VTX B15 | Rigging Manual 4.2 SUSPENDED ARRA YS Line Array Calculator checks the mechanical safety of suspended arrays and takes into consideration all variables that can affect the mechanical safety and safety factors. The software validates the mechanical stresses on the enclosures, speaker rigging components, and all accessories used as part of an array. -
Page 13: Ground-Stacked Arrays
VTX B15 | Rigging Manual 4.3 GROUND-ST ACKED ARRA YS Line Array Calculator checks for the mechanical safety for ground-stacked arrays. The software takes into consideration several vari- ables that can affect the stability of an array, including outside factors such as someone pushing on an array. Based on this data, LAC-3 generates a safety assessment factor and notifies the user of potential mechanical or stability problems. -
Page 14: Rigging System
VTX B15 | Rigging Manual 5 - RIGGING SYSTEM VTX B15 cabinets include a six-point, trigger operated, rigging mechanism that can be deployed to suspend up to 15 cabinets, de- pending on the configuration. The B15 rigging system enables forming either standalone arrays or mixed arrays using A6 full-range cabinets suspended under the B15s. -
Page 15: Rigging Mechanism
VTX B15 | Rigging Manual 5.2 RIGGING MECHANISM Each of the six B15 rigging bars incorporates a trigger operated, spring-loaded mechanism. Rigging bars automatically extend upwards once the user pulls the captive trigger located within the recess just below the rigging bar. Once extended, a label is visible to indicate that the link bar is in the extended position. - Page 16 VTX B15 | Rigging Manual When suspending multiple B15 cabinets together, all six rigging points (three per side) should be used for each B15 with the exception of the top cabinet, which connects to the array frame or suspension bar. Each attachment point will use one quick release pin, as illustrated below.

Page 17: Transportation
VTX B15 | Rigging Manual 6 - TRANSPORT A TION The VTX B15 ACC accessory kit includes a front face caster board for a single B15 and a protective cover. The ACC is an efficient solution for easy transportation and maximizing truck packs. Because of their small footprint, B15 subwoofers can be stacked on top of other equipment packed in a truck. -
Page 18: Caster Board Installation
VTX B15 | Rigging Manual 6.1 CASTER BOARD INST ALLA TION Two caster board tabs at the front of the B15 are used to secure the front face ACC caster board to the B15. The tabs are retractable and ship from the factory in the retracted position inside the B15. This orientation is ideal when B15s are used in an installation, where the tabs are not needed, but the tabs must be rotated to attach the caster board to the B15. -
Page 19: Caster Board Overview
VTX B15 | Rigging Manual 6.2 CASTER BOARD OVERVIEW The VTX B15 ACC caster board features two spring-loaded sliding pin locks (one on each side), which are used to attach the caster board to a B15 cabinet. The caster board seats on the B15 mounting tabs and is secured by the spring-loaded pin. TIP: The beveled edge on the pin allows you to attach the caster board with a forceful push, rather than needing to pull back the handle on the spring-loaded pin. -
Page 20: Caster Board Installation
VTX B15 | Rigging Manual 6.3 CASTER BOARD INST ALLA TION STEPS: • Slide either of teh ACC caster board mounting pins into one of the mounting tabs on the face of the B15 subwoofer. • Pull back the handle on the other pin mechanism, push the caster board onto the tab and release the handle. -
Page 21: Stacking Caster Boards
VTX B15 | Rigging Manual 6.4 ST ACKING CASTER BOARDS VTX B15 ACC Caster Boards can be stacked together for storage. The caster board’s handles and wheels were designed to allow stack- ing without having to touch or manually turn the wheels. When the ACC is held by the handle near its edge, gravity orients the wheels downward. -

Page 23: Mini Frame
VTX B15 | Rigging Manual 7 - MINI FRAME The VTX A6 MF Mini Frame is a lightweight, compact, and inexpensive array frame intended for suspending VTX A6 and VTX B15 arrays. The three-piece design is comprised of two side arms and one Spreader Bar. The side arms connect to the cabinets, and the Spreader Bar can be pinned to one of the 26 pick-point positions, providing excellent tilt resolution. -
Page 24: Attaching The Mini Frame
VTX B15 | Rigging Manual 7.2 A TT ACHING THE MINI FRAME The Mini Frame is always attached to the front four rigging bars of the top B15 subwoofer in an array. STEPS: • Extend the four front B15 rigging bars by releasing the recessed triggers located just below the rigging bars. •... - Page 25 VTX B15 | Rigging Manual STEPS: • Attach the two side arms to the B15 using the quick release pins attached to the side arms. • Pin the Spreader Bar to the desired pick-point position using the two pins attached to the Spreader Bar. Consult LAC-3 to determine proper hole position.

Page 31: Rc500
VTX B15 | Rigging Manual 7.7 RC500 The Mini Frame can be used in combination with the VTX RC500 Rotating Clamp. The VTX RC500 is a universal truss/pipe adapter designed for vertically suspending speaker arrays from standard truss structures or pipes. The RC500 supports arrays of up to 500 kg (1,100 lbs) and is compatible with array frames that support 1/2 inch shackles, such as the VTX A6 MF. -
Page 32: Suspension Bar
VTX B15 | Rigging Manual 8 - SUSPENSION BAR The VTX A6 SB Suspension Bar is a lightweight suspension bar for suspending A6 and B15 arrays when the additional functionality of the Mini Frame is not needed. A single Suspension Bar or dual bars can be used, depending on the array configuration and require- ments. -
Page 33: Attachment Options
VTX B15 | Rigging Manual 8.2 A TT ACHMENT OPTIONS The Suspension Bar can be connected to either the bottom or the top of a suspended mixed array of VTX A6s and B15s. To attach a Suspension Bar at the bottom of an array, the array attachment tabs will be used in conjunction with the pins from the cabinet. When connecting an SB at the top of an array, the pin from the Suspension Bar will be used. -
Page 34: Attaching The Suspension Bar

Page 39: Eyebolt Installation
VTX B15 | Rigging Manual 10 - EYEBOL T INST ALLA TION The B15G is acoustically the same as the B15 but designed without the integrated rigging system. This reduces weight and unneces- sary components for applications where portable rigging hardware is unnecessary. Instead, the B15G offers integrated M10 suspension points, making it ideal for fixed installations. -
Page 40: Pole Mount Attachment
VTX B15 | Rigging Manual 11 - POLE MOUNT A TT ACHMENT The B15 includes a standard M20 pole mount plate for attaching standard extension rods or other JBL supported acaccessories, like Base Plates. In this configuration, a load of up to 45 kg (100 lbs) can be placed on the extension rod as a static vertical load. For more information on the A6 Base Plate configuration limits, refer to the VTX A6 Rigging Manual. -
