Installation Series Dual 18" Subwoofer

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 IS1218 features NL4 and barrier strip inputs, plus 12 M10 fly points.
