Section 2. - GETTING STARTED WITH SYSTEM SETUP
The 4895 three-way HLA full-range speaker has a shipping weight of 230 pounds (105 kg). The 4897
dual-eighteen HLA subwoofer speaker, shipping weight of 240 pounds (110 kg). Both speakers are shipped
wrapped in cardboard and fit two per shipping pallet. At least one 4897 subwoofer is recommended for every two
4895 full-range speakers.
HLA Model 4895 Three-Way
Wheel Bars (HLA-WHEELS) are used for moving portable or touring HLA speaker systems. Each speaker
can be ordered with pairs of Wheel Bars for use in moving HLA speakers from the truck or storage to the position
in the venue where the array will be assembled.
A Wheel Bar is a 34-inch (86 cm) long L-shaped aluminum extrusion with two wheel-castors
mounted. Two Wheel Bars slide into guides along each side of the bottom of the speaker from the back. Wheel
Bars are shipped in pairs in a cardboard box weighing 25 lbs. (11 kg).
Connecting and lifting hardware
Connecting Bars (HLA-CB) are used in pairs to link one speaker to another. With one speaker
suspended above another, a Connecting Bar slides into both speakers' guides, one Connecting Bar on each side.
Two Connecting Bars are needed for every speaker that is not in the top row of a speaker array.
Lifting Bars (HLA-LB) are used in pairs to connect each speaker in the top row of an array to the
individual Truss Module above it with 1/2-inch screw pin anchor (SPA) Shackles. Lifting Bars slide into the two
guides on either side of the top of the speaker and each has two reinforced holes to accept suspension clips, or
Shackles. Two Lifting Bars are needed for every speaker in the top row of a hanging speaker array. This is the only
approved method for hanging HLA speakers. Four 1/2-inch SPA Shackles or load-rated safety-hook assemblies
can be used to attach an HLA-LB to the Truss Module above it (see Section 6, "Hanging and rigging information
for HLA arrays").
