Installation Series 15" Low Frequency Speaker

Yamaha's new Installation Series Speakers address a number of important issues that give them unprecedented performance and handling characteristics for live sound applications, including permanent installations. In particular, phase characteristics have been kept smooth and consistent throughout the entire series, so you can mix and match speakers to suit any system and venue without ending up with hot and dead spots due to phase interference. The IL1115 features 97dB sensitivity and 131dB max SPL.
