The Pulz EW1 Subwoofer has been specifically developed for playback of digital audio soundtracks in cinema theatres where high quality audio playback needs to be achieved at a moderate budget. The system is capable of high power output, low distortion and smooth response to the lowest audible frequencies.

The 18” driver is loaded in a direct radiator bass-reflex enclosure. It has a 3” high temperature stabilized voice coil for high power handling and reduced power compression. The specially treated cone is weather resistant and can withstand extremely severe climatic conditions. The large port area reduces turbulence at full power output and low frequencies.

The EW1 is recommended where long term reliability is of prime importance.
