Installed Sound Applications
Compact and elegant, the Alien 51S is a recessed speaker system designed for demanding background installations where wide dispersion and high quality audio reproduction is needed.
Designed around a 5" coaxial drive unit with a 3/4" neodymium tweeter, the Alien 51S offers ultimate clarity and a wide and well-controlled dispersion. The compact design integrates a passive crossover and a 100/70V transformer into the housing and allows the user to operate the speaker from 100V amplifiers, too.
Because it is based on the same cabinet as the Alien 05 color changer, installing multiple Alien products - both color changers and speakers - is easy and cost effective.
Useful in a wide variety of applications, the 110-degree acoustic coverage pattern ensures even sound pressure and tonal balance throughout the coverage area. As a special feature, the Alien S51 comes with a software program that calculates the number of speakers needed in a given venue.
The Alien 51 specs include a power rating IEC268 of 50 watt, peak power rating of 200 watt, sensitivity ((1w/1m) of 88 dB, 105 dB max. SPL, calculated continuous 105 dB, 111 dB peak SPL, frequency range from 90 Hz to 20 kHz, and a weight of 2 kg.
