With a pair of 18" Differential Drive woofers, it handles an amazing 1600W power (continuous). Large, open ducts minimize port turbulence and the heavily braced JBL enclosure assures tight, solid bass response. Designed to present a minimum frontal area, the subwoofer enclosure offers complete input connection flexibility with 2 Neutrik Speakon jacks. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2 while an internal connector allows you to drive each woofer from a separate amplifier channel. The speaker cab is constructed of top-quality birch plywood and coated in rugged DuraFlex. Each woofer is housed in an isolated chamber and the enclosure is heavily braced to maximize low-frequency performance. The attractive CNC machined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide the JBL SRX728S with additional driver protection and a very professional appearance. This subwoofer excels when paired with the PA speakers (sold separately).JBL SRX728S Dual 18 Subwoofer Features:High-power subwoofer2 - 2268H Differential Drive, neodymium magnet, 18" woofersPower Rating (Continuous/Program/Peak): 1600W/3200W/6400WFront-loaded vented enclosure2 Neutrik Speakon NL-4 connectorsExternal switch selects either contacts +1/-1 or +2/-2Internal connector separates each woofer into 2 channelsBirch plywood constructionHeavily bracedRugged DuraFlex finishIsolated chamber for each wooferCNC machined, 16-gauge steel grilleJBL SRX728S Dual 18 Subwoofer Specifications:Frequency Range (-10 dB): 27Hz—220HzFrequency Response (±3 dB): 33Hz—220HzInput Connection Modes: Switchable, +1/-1 or +2/-2; Internally selectable, Parallel or DiscreteRecommended Crossover Frequencies: 80Hz, 24dB/octave HPF; 80Hz, 24dB/octave LPFPower Rating (Continuous/Program/Peak): Parallel: 1600W/3200W/6400WMaximum SPL: 136dB SPL peakSensitivity (1w @ 1m): 98dB SPLLF Driver: 2 x JBL 2268H 18" Differential Drive woofer with neodymium-magnet and dual voice-coilsNominal Impedance: 4 ohms parallel; 8 ohms x 2 active discreteEnclosure: Rectangular, 18mm, 13-ply birch plywoodFinish: Black DuraFlex finishGrille: Powder coated, black, 16-gauge perforated steel with acoustical transparent charcoal foam backing.Dimensions: 42"W x 23-3/4"H x 33"DNet Weight: 166-1/2 lbs.
