JBL’ s new K151 is a powerhouse 18-inch loudspeaker made especially for electric bass, and designed to sound great in horn- loaded or reflex enclosures.
It delivers fantastic low frequency punch, it’s extremely efficient and has some very unique differences-like tight, crisp bass and superb definition: charac- teristics of lead instrument loudspeakers but unheard of from 18-inchers – until the Kl 51 entered the picture.
