LX-18EV2 Owner’s Manual
Thank you for choosing the B-52 LX-18EV2 subwoofer. For best performance
and years of trouble-free operation, please read this Owner’s Manual before
use. Please follow and keep these instructions. Please heed all warnings.
PRECAUTIONS:
1) Location of Subwoofer:
a. Avoid areas with high temperature (i.e. near heater).
b. Keep speakers out of extended or direct sunlight.
c. The LX-18EV2 is intended for portable use in which the speaker should
be placed on the floor, stage or a solid platform. Do not place on
unstable or non-level surfaces.
d. The LX-18EV2 can produce high-energy levels. When placed on slippery
surfaces, such as polished wood or smooth tiles, the subwoofer may
move because of its intense bass output. Precautions should be
taken to ensure the subwoofer does not fall off a stage or raised surface.
e. If a full-range cabinet is placed on top of the LX-18EV2, it should be
secured to the subwoofer to prevent the speaker from falling off.
2) Hearing damage, prolonged exposure to excessive SPL:
B-52 Pro-Audio speakers, especially the LX-18EV2s, are capable of producing sound pressure levels (SPL) sufficient to cause permanent
hearing damage to performers, production crews or people in the
audience! Adequate hearing protection devices are recommended.
Caution should be taken to avoid extended exposure to SPL in
excess of 90 dBA or at a level that causes discomfort.
3) Do Not Suspend:
The LX-18EV2 is not intended for suspension or hanging. Under NO
circumstance should you attempt to suspend or hang this subwoofer.
POWER UP / DOWN YOUR SYSTEM:
1) Your system must be turned completely OFF before connecting or
disconnecting the LX-18EV2. Connecting or disconnecting the LX-18EV2
while the sound system in ON may damage the subwoofer and the audio
components in your sound system.
2) Make sure the gain or level control(s) on the amplifier(s) is turned all the
way down when turning the system on or off!
3) Disconnect the LX-18EV2 prior to moving the sound system or the
subwoofer.
CABLING CAUTION
Use shielded speaker cable with stranded conductors. Do not use
audio cable that is insufficiently rated for the amplifier’s maximum
output amperage. 16-gauge or larger wire is recommended. Longer
cable run distances require larger cable. Use of inappropriate cable
can create a fire hazard!

MAXIMUM BASS
OUTPUT
The LX-18EV2 should be
arrayed in groups of two or
four and placed adjacent
to structural surfaces. This
will act to extend the horn
wall of the LX-18EV2 and
will enhance low-frequency
output. Placing
subwoofers adjacent to
each other results in a
coupling effect, which will
increase the total bass output of the system.
CHOOSING AN AMPLIFIER:
1) It is important to choose an amplifier that matches the power
rating of the LX-18EV2 (see specifications on back page).
2) When using TWO (2) LX-18EV2 subwoofers in you system you
may choose an amplifier that delivers up to 750 watts @ 8 ohm
stereo or an amplifier that delivers up to 1500 watts @ 4-ohm
bridge (when connecting two LX-18EV2 in parallel). Other
combinations are possible––consult your authorized dealer or
call B-52 for additional details. See Connection Diagram (right).
3) Use caution when using large amplifiers. All amplifiers are
capable of putting out much more power than they rated for.
The amplifiers rating is specified as undistorted output (low
THD––total harmonic distortion). Amplifiers are capable of
producing much greater power that they are rated for when
driven into clipping.
4) Under powering the LX-18EV2 may also damage the
subwoofer. Using a small amplifier and clipping its high output
signal could damage the subwoofer. Clipping the amplifier may
distort the signal and cause over heating of the voice coil.

USING AN ELECTRONIC CROSSOVER
For optimal performance, it is extremely important that an
electronic crossover be used in the audio system. An electronic
crossover will provide a low-pass output allowing the LX-18EV2 to
only play low frequencies. B-52 recommends setting your
low-pass crossover filter between 80 to 120 Hz, depending upon
the venue and sound desired. In case of doubt, set the low-pass
crossover to 100 Hz.
It is highly recommended to use an electronic crossover with
24 dB per octave slopes or higher. If your amplifier or electronic
crossover provides a 30 Hz subsonic filter, make sure this filter is
turned ON. The subsonic filter will prevent the subwoofer from
reproducing frequencies below 30 Hz. At high SPL, frequencies
lower than 30 Hz can damage to the subwoofer.
