Redback “One-Shot ” speaker assemblies install in seconds. They simply snap fit to any 10-13mm thickness ceiling by means of the integral pressure clips. The labour cost savings for the pro sound installer are both obvious and substantial. The snap clip material is formulated to retain long service life strength and spring action, ensuring a snug vibration free fit to either gyprock tiles, mineral fibre tiles or fixed gyprock ceilings. This model is a twin cone speaker suitable for commercial and industrial use, utilising 100V line systems and fitted with a 2 way terminal block. Attention PA Installers! Using these speaker assemblies greatly reduces installation time compared to a standard speaker & grill combination. Typically, you will save about 5 minutes per speaker point. This equates to a significant saving in labour costs. Engineered and manufactured to stringent specifications ensuring maximum reliability under all operating conditions. Each driver has a power rating well above the max tapping of the transformer, ensuring reliable operation and excellent longevity.
