5W 100V EWIS 4" (100mm) Speaker For One-Shot Grille

This custom designed speaker and transformer combination has been specifically engineered to ensure a wide frequency range and dispersion angle, plus a high sound pressure level (SPL) ensuring excellent music and speech intelligibility; which is highly desirable for emergency paging applications. Modelled on the popular Redback® One-Shot design, the ‘rat trap’ uses an ingenious patented spring mechanism that snaps like a rat trap when activated. Includes three retaining clips ensuring the grille fits snugly to the ceiling without sagging or drooping, even in soft ceilings. For best results we recommend using the T 2312A holesaw. Fitted with 4 way wire protect terminal block, 22µF bipolar capacitor, transformer safety cover and cable restraint plate as required by Australian standard.
