PRODUCT DESCRIPTION

The Impact 50 is an ultra–compact passive sound reinforcement loudspeaker
designed for applications wherever a very small enclosure is required to
reproduce sound. The Impact 50 drive units are a 5” high efficiency low/mid
transducer and a 1” ferrofluid-cooled soft dome tweeter. It includes an internal
second order high pass filter network designed to give a very clean transition
between the two drive units while ensuring that the tweeter is protected from
harmful low frequency signals.
The Impact 50 is intended for fixed installations and as such is supplied as
standard with the WB-50 adjustable wall mounting bracket, allowing horizontal
and vertical adjustment.

The constant voltage version (Impact 50T) has been designed for use in 70 volt
and 100 volt distributed systems where long cable runs, and a large number of
loudspeaker units, make the use of a low impedance speaker impractical. The
internal line transformer is a high quality type offering wide bandwidth and
three power taps.

A weather-resistant option is available for use outdoors or under conditions of
high humidity. It is supplied with a rust–proof grille and stainless steel fixings.

SYSTEM REQUIREMENTS

The Impact 50 is a passive loudspeaker system. This means that it requires only
one amplifier channel for correct operation, the frequency splitting between the
low frequency driver and the high frequency driver being accomplished by the
internal passive crossover network built into each enclosure.

Passive subwoofer enclosures may be used in conjunction with the Impact 50 in
order to extend the frequency range from the system. The TSB-110, a dual–coil,
two–channel band–pass subwoofer, is recommended for this purpose. When
using the TSB-110, additional power amplifiers are not required since the
subwoofer contains passive crossovers for both left and right channels, allowing
up to eight Impact 50 speakers to be connected as satellite units.

If subwoofer enclosures are used in a bi–amplified system in conjunction with
Impact 50 enclosures, additional amplifier channels and external electronic
crossovers will be required. The LMS-D4 loudspeaker management system is
recommended for this purpose.
