System Specifications:Frequency Range (-10 dB): 38 Hz-160 HzContinuous Program Power Capacity1: 340 Watts (both inputs driven)170 Watts (each input) x 2Sensitivity2: 100 dB (1 W, 1 m) at corner junction (π/2 loading)97 dB, at two boundary junction (π loading)Nominal Impedance: 8 ohms per input; 4 ohms total with both inputsparalleled.Network Filter to Subwoofer: 12 dB/oct low-pass (per input), 160 HzAcoustic Filtering: 6 dB/oct low-pass filtering via slot-load design, 80HzNetwork Filter to Satellite Outputs: 6 dB/oct high-pass (per output)Satellite Impedance: 4Ω load per Satellite Output recommendedOptimum System Configuration: Four JBL Control 23 satellite speakers (two on eachSB-2 satellite output) provide optimum sensitivitybalance and impedance loading, resulting in full-range38 Hz - 22 kHz system performance. Broadbandimpedance is 4Ω per input x 2 channels.Driver: 250 mm (10 in) long-throw with dual voice coilsEnclosure Material: Particle BoardTerminations: Spring terminals, accepts banana plugs. Left In,Right In, Left Satellite Out, and Right Satellite OutInstallation Accessories: MTC-SB2W for installing SB-2 onto a wall or into acornerMTC-SB2C for suspending SB-2 from ceilingDimensions (H x W x D): 394 x 585 x 343mm (15.5 x 23.0 x 13.5 in)Net Weight: 19.1 kg (42 lbs)Shipping Weight: 22.7 kg (50 lbs)1 Continuous program is a conservative expression of the system’s ability to handle normalspeech and music program material and is defined as 3 dB greater than the continuous pinknoise rating (AES pink noise from 30Hz-300Hz with a 6 dB crest factor, for 100 hourscontinuously).2 Sensitivity rated in the subwoofer band, from 60Hz to 90Hz, both inputs driven 1/2W each(1W total). Sensitivity with 1W to each input is 3 dB higher.JBL continually engages in research to produce improvement. New materials, productionmethods, and design refinements are introduced into existing products without notice as aroutine expression of this philosophy. For this reason, any current JBL product may differ insome respect from its published description, but will always equal or exceed the originaldesign specifications unless otherwise stated.Control®SB-2 Stereo InputDual Coil SubwooferKey Features: Component: 250 mm (10 in) dualvoice coil transducer Stereo inputs with high-passoutputs for satellite speakers Slot-load vented bandpass design Complements full-rangeControl Contractor Series systems High Sensitivity: 100 dB, 1 W, 1 mThe Control SB-2 provides lowfrequency reinforcement insubwoofer/satellite systems. TheControl SB-2 is ideal for foregroundmusic and music/paging systems inrestaurants, retail establishments,theme bars, music cafes, healthclubs, and other indoorapplications.The unique slot-load venteddesign provides acoustic low-passfiltering. Compared to traditionalbandpass subwoofers, the SB-2offers superior musical clarity andbass impact.The satellite outputs are high-pass filtered, reducing overall sys-tem distortion by eliminating theneed for the satellite speakers toreproduce frequencies in the lowbass range. The satellites operatemore efficiently, maintaining excel-lent midrange clarity and realism inmusic and paging. The high-passfiltering also allows a greater num-ber of satellite speakers to be paral-leled in the system by increasingthe impedance the amplifier sees inthe subwoofer range. The stereoinputs are 8 ohms each.The combination of the satellitehigh-pass filtering, the acoustic slot-load filtering and a built-in 2ndorder low-pass crossover networkresults in smoother overall systemfrequency response and virtuallyeliminates the “muddiness” typicalof other subwoofer/satellite systemsby reducing frequency overlap inthe low midrange.Professional Series
