CHOOSING AN AMPLIFIER:
LX-18EV2 CONNECTION DIAGRAMS
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.

LX-18EV2
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.

Connecting two LX-18EV2 subwoofers in
parallel results in a 4 ohm load.
There are numerous other configurations available.
Please consult your Authorized B-52 Dealer or
contact B-52’s Customer Service.
Important: When connecting a speaker to an amplifier or when connecting two speakers together, it
is important to match the polarity (+/-). Connect positive-to-positive and negative-to negative.
