I have been searching for just the right hardware to hang my speaker arrays so that they have perfect coverage and a clean look. The Zbeam, from Polar Focus, looks like it might be just the solution I’m looking for.
The Zbeam is two load-bearing square tubes conjoined by a center-located friction bearing, which permits easy adjustment. The top half of the Zbeam is secured to a truss by first installing what amounts to a half-swivel clamp with a fixed forged eye attached to it.
Zbeams have graduated, machined holes to allow attachment at a variety of convenient locations, via a shackle. Once installed, you can avail yourself of the silk-screened angle locators on the topside of the bottom half of the rig. Accompanying the Zbeams was a complement of very well-made hardware, including shackles, forged eyebolts, the aforementioned swivel clamps and a unique hanging bridle system that is composed of wire rope, assemblies and a threaded compression fitting that the wire rope passes through, securing the pull-back axis of the speaker.
I put the Zbeams to the test at a local four-star resort, where flying your speaker system is a must. I flew two Yorkville EF508 speaker cabinets from the 40′ lighting truss, which was suspended by two-ton rigging points in the ceiling. We easily installed the swivel clamps, followed by the Zbeams to the clamps’ forged eyes. We threaded the forged eyebolts into the Yorkville cabinets and shackled the two front speaker hang points to the Zbeams.
The hanging bridle attaches to the two forward speaker points; a pulley and the threaded compression fitting allow the bridle to reach back to a vertical adjustment pull-back point. The horizontal angle can be precisely adjusted by a simple push/pull maneuver.
The Zbeam allows you to fly any speaker system with maximum ease. The components are of the highest quality and weighs only 14 lbs. The black Zbeam lists at $360 while the white is $380. If you are looking for the ultimate in a rigging/flying system, I highly recommend the Zbeam.
