DESCRIPTION

JBL knows that everybody has different tastes in bass — that's why they designed GTO Series subwoofers to work great in sealed, vented, or bandpass enclosures. JBL packed over a half century of speaker-building experience into creating these GTO subs, so you can hear bass the way you like it!

The GT150 15" subwoofer boasts a polypropylene cone that's lightweight and ultra-efficient, so you won't need as much power to drive your low notes. The cone and its butyl rubber surround are impervious to moisture and temperature extremes so you'll be hearing great bass for a long, long time. Dual 40-ounce magnets and a progressive spider exert maximum control over cone movement — this woofer won't bottom out when the going gets tough!
