Product Description
The ISM™5Tx is a small format 2-way speaker system that is perfect for any application
from foreground music to speech reinforcement. The ISM™5Tx has a hi-fi sound
character with good clarity, which is ideal for music systems in bars, taverns, arenas,
lounges, arcades or anywhere multi-channel, multi-speaker sound systems are required.
This speaker utilizes a specially designed 5” woofer and a 1” poly dome tweeter. The
lightweight and rugged injection-molded cabinet is weather-resistant for indoor or
outdoor use. A curved black metal perforated grille provides driver protection and a
professional appearance.
The compact, lightweight package coupled with its smooth response makes this system
ideal for the smaller venues where space is at a premium.
The ISM™5Tx speaker system is rated at 80W program power handling. Spring-loaded
terminal input connectors make hook-up extremely simple. Incorporation of a 70.7 volt
line transformer with taps at 16W, 8W, 4W and 2W allow easy use with 70.7 volt
distributed systems. The tap selector switch also has an 8 ohm input option, so the
ISM™5Tx speaker system can be used with a direct connection to a power amp,
providing unequaled versatility.

Mounting and Installation
CAUTION!
Before attempting to suspend or mount this speaker, consult a certified structural
engineer. Speaker can fall from improper suspension, resulting in serious injury and
property damage. The ISM™5Tx can be mounted using the supplied mounting bracket.
Use only the correct mating hardware and appropriate bracket mounting hardware. All
associated rigging is the responsibility of others.

CAUTION!
When using the 70.7V distribution system transformer inputs, it is typically required that
an infrasonic filter be used to prevent saturation of the transformer, and possible
overloading of the power amplifier. A minimum of an 18 dB/octave high-pass filter set to
a –3 dB point of 80 Hz or higher should be used to filter the low frequencies. It is
recommended that the filter be a 24 dB/octave Linkwitz-Riley type set to 65 Hz (-6 dB
point) for maximum reliability and performance.
Specifications
Frequency Range: 65Hz – 20kHz (-10 db, 1 meter on-axis, swept-sine in ½
space environment)
Frequency Response: 92Hz – 18kHz (+/- 4db, 1 meter on-axis, swept-sine in ½
space environment)
Power Handling: 8 Ohm Thru Mode: 40 W continuous, 80 W program, 160 W
peak. Transformer taps for 70.7 volt operation: 16W, 8W, 4W and 2W
Sound Pressure Level, 1 Watt, 1 meter in anechoic environment: 88 dB SPL,
(2.83V input, 8 ohm thru mode). Transformer Losses, Less than 1 dB when in
70.7V input mode.
Maximum Sound Pressure Level (1 meter, 8 ohm thru mode): 103 dB SPL
continuous, 109 dB SPL peak
Nominal Radiation Angle: 110 degrees horizontal by 110 degrees vertical
Transducer Complement: Low Frequency Section: 1x 5” high performance
water-resistant woofer with rubber surround. High Frequency Section: 1x1”
polydome dynamic tweeter with built-in diffusion cap.
Crossover Frequency (internal passive): 7.4 kHz
Crossover Type & Slope: Internal passive; 12 dB/octave (2nd order), High pass
for tweeter, and 6 dB/octave (1st order) Low pass for woofer
Impedance (Z) for 8 ohms Thru connection: Nominal: 8 ohms
Minimum: 6.6 ohms
Input Connections: Spring-loaded push terminals
Transformer Taps (Transformer Input Mode): 70.7V taps: 16W, 8W, 4W, 2W
Caution: When using transformer input, an infra-sonic (high-pass) filter
should be used to prevent transformer saturation and overload. This will
increase reliability and decrease distortion. We recommend a setting of 80
Hz –3 dB point.
