JBL continually strives to update and improve existing products, as well as create new ones. The
specifications and details in this and related JBL publications are therefore subject to change without notice.
* The Peak Dynamic Power is measured by recording the highest center-to-peak voltage measured across the output of
a resistive load equal to minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.

Adjust Level
Turn your Subwoofer-Level Control ¡ up to the "5" position
(halfway). If no sound emanates from the subwoofer, check the
AC-line cord and input cables. Are the connectors on the cables
making proper contact? Is the AC plug connected to a "live"
receptacle? Has the Power Switch ¶ been pressed to the "On"
position? Once you have confirmed that the subwoofer is active,
proceed by playing a CD, record or cassette. Use a selection that
has ample bass information.
Set the overall volume control of the preamplifier or stereo to a
comfortable level. Adjust the Subwoofer-Level Control ¡ until
you obtain a pleasing blend of bass. Bass response should not
overpower the room but rather be adjusted so there is a harmonious
blend across the entire musical range. Many users have a tendency
to set the subwoofer volume too loud, adhering to the belief that a
subwoofer is there to produce lots of bass. This is not entirely true.
A subwoofer is there to enhance bass, extending the response of
the entire system so the bass can be felt as well as heard. However,
overall balance must be maintained or the music will not sound
natural. An experienced listener will set the volume of the subwoofer
so its impact on bass response is always there but never obtrusive.

BALBOA SUB10 Test Set Up and Procedure
SYSTEM AURAL SWEEP TEST
Equipment needed:
· Function/signal generator/sweep generator
· Integrated Amplifier
· Multimeter
· Speaker cables
General Unit Function (UUT = Unit Under Test)
Switches/knobs on the amplifier faceplate:
Low Pass Frequency Adjust full CW (150Hz)
Phase switch either position
1. From the signal generator, Connect both right and left line level inputs (RCA) not the LFE jack - to signal
generator and UUT. Use Y-cable if necessary from mono source.
2. On the amplifier, turn the LEVEL control full Counterclockwise (Min).
3. Turn on generator, adjust to 100mV, 50 Hz.
4. Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max).
5. LED should now be Green; immediate bass response should be heard and felt from rear port tube opening.
6. Turn off generator, turn LEVEL control fully Counterclockwise (Min), disconnect RCA cable.
Sweep Function
1. Follow steps 1-6 above, using a sweep generator as a signal source.
2. Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or
any other noises. If any unusual noises are heard, remove woofer and test.
Driver Function (Woofer)
1. Remove woofer from cabinet; detach + and - wire clips.
2. Check DC resistance of woofer; it should be 3.3 ohms ±10%.
3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated
amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
