ISM 5Tx™

5″ Two-Way Weather-Resistant 70V & Low Impedance Loudspeaker


The ISM 5Tx™ is a small format two-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” polydome 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 80 Watts 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 Ohms input option, so the ISM 5Tx speaker system can be used with a direct connection to a power amp, providing unequaled versatility.
