IL 15.1

Fullrange cabinet featuring extended low end response and
high load-handling for high-quality sound reinforcement for
public address and music bars, live clubs, smaller dance clubs,
theaters and similar venues and applications. The IL 15.1 may
be deployed either as a fullrange cabinet or as a mid/high-range
cabinet in combination with the HK AUDIO subwoofers
IL 115 Sub, IL 118 Sub and IL 218 Sub.
Offering plenty of punch and able to render speech and music
with amazing clarity, this is the ideal enclosure for short-to-medium-
throw applications. Passive crossover on board.
