• Used to control powerful primary reflections
• 'Roman Pillar' shape is ideal for spacing along walls
• Easy-to-install on practically any surface
• Adapts well to most architectural designs

Broadway Control Columns present an attractive, 'easy-to-install' solution for acoustic treatment where you want to control primary reflections, eliminate flutter echo and reduce standing waves.

Made from high density 6lb per cubic foot high density glass wool, Control Columns are designed to be arranged in a ‘spaced array’ to treat bothersome first order reflections that interact with the sound source and the listener. The panels are typically spread across a wall surface leaving space in between each panel. This allows some of the energy to reflect back into the room so as not to completely deaden the space while maximising the panel’s absorptive efficiency.

The Control Column's long narrow design is reminiscent of the historic 'Roman Pillar' making it an ideal compliment more demanding architectural designs. This makes the Control Columns an excellent choice for LEDE live-end / dead-end studio designs and home theatres. For those with creative flair, Control Columns can be combined with Primacoustic Accent panels to create an attractive solution for office spaces, board rooms, restaurants and lobbies that often need to be tamed in effort to reduce the reverberant field.

Broadway Control Columns come in a choice of 1", 2" and 3" thick panels with choice of square or bevelled edge. Color options include black, grey or beige.

*Notice: In our opinion, the short form sound absorption coefficient does not provide reliable data regarding the performance of a particular panel versus the problem frequency. This data is provided for comparison sake only. Please view the full frequency chart below to ensure that the panel you are considering will actually attenuate the frequencies you are attempting to absorb.

Fire and Burn Performance for Broadway Panel Component

Test	Class	Flame Spread	Smoke Density	Test Data
ASTM E 84	1 or A	15	155
CAN/UL-S102	1 or A	15	155
Test data provided by Bodycote Materials Testing Inc. This method, designated as ASTM E 84-05, "Standard Method of Test for Surface Burning Characteristics of Building Materials", is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment under actual fire condition.
