15" (380mm) Passive Subwoofer

The S2S-EX Ported Subwoofer is designed to deliver the powerful, deep bass that is demanded by the movie soundtracks and music of today. It has an impressive 15″ (380mm) cast-frame woofer (Model: W1500H) that is capable of producing the deepest lows without distortion. The ingenious Kevlar®-Kapok material in the woofer cone provides the rigidity needed to realistically replicate your favorite film’s special effects and musical performances without any additional coloration. The industrial grade cabinetry uses internal interlocking horizontal and vertical braces to provide a strong, rigid enclosure. JBL’s patented SlipStream™ low frequency port design works in concert with the woofer to produce deep bass response at all playback levels. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence. Added to these features is the ability of the S2S-EX to be oriented either vertically or horizontally which provides flexibility in built-in applications. The S2S-EX is also a direct-fit replacement for older S2S subwoofers in existing systems. The S2S-EX gives multi-channel systems just the bass they are looking for.
