System Specifications:

Frequency Range (-10 dB): 38 Hz-160 Hz

Continuous Program Power Capacity1: 340 Watts (both inputs driven)

170 Watts (each input) x 2

Sensitivity2: 100 dB (1 W, 1 m) at corner junction ( /2 loading)π

97 dB, at two boundary junction (πloading)

Nominal Impedance: 8 ohms per input; 4 ohms total with both inputs

paralleled.

Network Filter to Subwoofer: 12 dB/oct low-pass (per input), 160 Hz

Acoustic Filtering: 6 dB/oct low-pass filtering via slot-load design, 80Hz

Network Filter to Satellite Outputs: 6 dB/oct high-pass (per output)

Satellite Impedance: 4Ωload per Satellite Output recommended

Optimum System Configuration: Four JBL Control 23 satellite speakers (two on each

SB-2 satellite output) provide optimum sensitivity

balance and impedance loading, resulting in full-range

38 Hz - 22 kHz system performance. Broadband

impedance is 4Ωper input x 2 channels.

Driver: 250 mm (10 in) long-throw with dual voice coils

Enclosure Material: Particle Board

Terminations: Spring terminals, accepts banana plugs. Left In,

Right In, Left Satellite Out, and Right Satellite Out

Installation Accessories: MTC-SB2W for installing SB-2 onto a wall or into a

corner

MTC-SB2C for suspending SB-2 from ceiling

Dimensions (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)

1Continuous program is a conservative expression of the system’s ability to handle normal

speech and music program material and is defined as 3 dB greater than the continuous pink

noise rating (AES pink noise from 30Hz-300Hz with a 6 dB crest factor, for 100 hours

continuously).

2Sensitivity 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, production

methods, and design refinements are introduced into existing products without notice as a

routine expression of this philosophy. For this reason, any current JBL product may differ in

some respect from its published description, but will always equal or exceed the original

design specifications unless otherwise stated.

The Control SB-2 provides low

frequency reinforcement in

subwoofer/satellite systems. The

Control SB-2 is ideal for foreground

music and music/paging systems in

restaurants, retail establishments,

theme bars, music cafes, health

clubs, and other indoor

applications.

The unique slot-load vented

design provides acoustic low-pass

filtering. Compared to traditional

bandpass subwoofers, the SB-2

offers superior musical clarity and

bass impact.

The satellite outputs are high-

pass filtered, reducing overall sys-

tem distortion by eliminating the

need for the satellite speakers to

reproduce frequencies in the low

bass range. The satellites operate

more efficiently, maintaining excel-

lent midrange clarity and realism in

music and paging. The high-pass

filtering also allows a greater num-

ber of satellite speakers to be paral-

leled in the system by increasing

the impedance the amplifier sees in

the subwoofer range. The stereo

inputs are 8 ohms each.

The combination of the satellite

high-pass filtering, the acoustic slot-

load filtering and a built-in 2nd

order low-pass crossover network

results in smoother overall system

frequency response and virtually

eliminates the “muddiness” typical

of other subwoofer/satellite systems

by reducing frequency overlap in

the low midrange.

Professional Series

䉴Control®SB-2 Stereo Input Dual Coil Subwoofer

The Control SB-2 incorporates a long-excursion

250mm (10in) transducer providing usable output to

38 Hz. Dual voice coils on the transducer allow the

single cabinet to reproduce subwoofer frequencies

for both the left and right channels while maintain-

ing channel separation in the satellites.

Subwoofer placement can be used as a tool for

adjusting output sensitivity to match that of the

satellite speakers and the requirements of the

application. Positioning the SB-2 at the junction of

three boundaries (i.e. - at a floor/wall/wall or

ceiling/wall/wall junction) yields maximum output

sensitivity for use with high sensitivity satellites or

for subwoofer-heavy applications. Placement at

the junction of two boundaries (i.e. - floor/wall,

ceiling/wall or wall/wall) reduces the subwoofer

level by 3 dB. Placement in the middle of a single

boundary (i.e. - wall, floor or ceiling) further

reduces subwoofer output sensitivity by another

3 dB, to match with less efficient or higher

impedance satellite systems. The Control SB-2 is not

weather resistant and should not be used outdoors.
