Line array rigging for Sinnissippi Music Shell

Mik Moore of Clearwing Productions contacted us for this challenging line array installation rigging used at the Sinnissippi Music Shell in Rockford, IL.


The speakers were 3 L-Acoustics SB15m subwoofers, along with 10 KIVA II mid-hi boxes as a center cluster. The cluster needed to be weather rated as it is left installed from late spring through early autumn. The square frame at the top allows for an installation hoist to lift the cluster into position; after set up the hoist can be removed.

At the end of the performance season, the procedure is reversed. Braces from the bottom of the cluster to left and right wood beams lock off the cluster and keep it from swinging in the wind.

Raven Line Array Frame for Renkus-Heinz Varia

Polar Focus would like to announce an addition to our OEM line array rigging solutions.  Designed for increased functionality and lower installation cost, our Raven frame for the popular Renkus-Heinz Varia family of loudspeakers allows infinitely adjustable pan and tilt under full load.

The ORH-VARIA-Raven fastens to the loudspeakers using the integrated side plate rigging hardware included with the Varia speaker. The Raven frame’s mounting hardware allows for super easy and lightning fast mating to the loudspeaker.  A wide range of quick pin accessories makes system design startlingly simple.

We’re taking this rig on the road – check out the Raven frame at Polar Focus booth #6350 at Infocomm 2017 in Orlando.

JBL VRX932 Rigging

Chris Miller from CTM Sound in Sacramento, CA contacted us for assistance rigging these JBL Professional VRX932 clusters at a local ice rink. Polar Focus provided custom made wood beam brackets along with our Blackbird aftermarket frame for the JBL VRX932 family. Using this kit, Chris had full control of pan and tilt under load.

Here’s his feedback for the project: “What an easy way to rig some speakers! Thanks again for all the help.” And it looks fabulous too!

Polar Focus rigging at Penn State

This gymnasium at Penn State Altoona recently had a new sound system installed
by Steve Obenreder of RPC Video in Verona, PA.

PSU Altoona Adler Gym EDIT

For the Adler Athletic Complex, Polar Focus supplied roof attachment, along with
pan and tilt capability for each of the 16 Electro-Voice EVH1152D loudspeakers.

Polar Focus also provided PE stamped drawings for the state of PA.
This was a neat and clean job by the team at RPC Video. Go Nittany Lions!

Reformation Lutheran Church

Paul Colella of McClelland Sound in Wichita asked Polar Focus to design rigging for this installation at Reformation Lutheran Church.

This cluster utilized 10 JBL Professional VT4886 line array modules as a main cluster, 1 JBL AC2895 as a fill box, and a Danley Sound Labs, Inc. TH118i subwoofer. All of the speakers were supported from a steel I beam in a recessed cavity behind sheetrock at the peak of the roof. The line array was interesting in that we used hidden counterweights on the front of the line array frame to avoid using a pull back. Of course, the main cluster has infinitely adjustable tilt under load.

Clean installation with custom color on speakers and rigging by Paul and his team.

Orpheum Theater

Steve Olson of the Orpheum Theatre in Minneapolis called us for help upgrading the house sound system, including new rigging. Steve elected to use a center cluster of ten Electro-Voice XLD291 along with left and right clusters each using one EVF 2151D with an EVH 1152S.

Each side cluster connected into a group using the Electro-Voice grouping hardware. Polar Focus provided the powdercoated lighting truss, and all of the hardware down to the tops of the speakers. Polar Focus also provided PE stamped drawings for the state of Minnesota for this design. Here are some photos Steve sent us of the completed installation. Beautiful work, Steve!
