Powered Subwoofers LPS08 • LPS10 • LPS12

Instruction Guide and Owner’s Manual

Description

Lava Subwoofers were designed and built to provide
the incredibly powerful low frequency reproduction
demanded by today's audio/video. These models
feature a high-powered amplifier, a coated cellulose
composite driver, and a sleekly designed cabinet that
will fit into any room's decor.

Lava amplifiers use a special design; with a
heavy-duty transformer to minimize unwanted heat
build up, the amps can drive harder and longer. This
also means very low distortion and powerful
reproduction of music and theater sound. With this
kind of efficiency from an amplifier, you’re guaranteed
to get strong and clean bass at any listening level.

The coated cellulose composite drivers incorporate
large magnets and voice coils which allow for high
volumes and deep, rolling bass. Every subwoofer
driver is tested to make sure that it holds up to Lava
Subwoofer's strict specifications.

The cabinet features two large, front-loaded ports
located below the woofer. Ports this size allow for
more air to escape the cabinet when the subwoofer is
playing at high volumes, which provides deeper bass
and longer life to the subwoofer and amplifier. Since
the ports are located on the front of the cabinet, the
subwoofer can be mounted into cabinetry without
sacrificing any performance. The cabinet also features
a black vinyl, lightly textured finish, and smoothly
rounded corners.

INSPECT Your Subwoofer!

Now is the time to inspect your subwoofer for any
damage. When it left our factory, it was inspected to
make sure it was in perfect condition. If for some
reason it was damaged in transit to you, please let us
know right away so corrective action can be taken.

CAUTION: For NO reason should you
open this subwoofer. This will void the
warranty!

To reduce the risk of electrical shock and fire, do not
remove the amplifier panel from the back of the
cabinet or remove the driver from the front of the
cabinet. All service to this product MUST be done by
Lava Subwoofers.

Before installing the subwoofer, please read the
following instructions:

• Always turn off the power of your receiver/preamp

and the powered subwoofer.

• When turning your amplifier/receiver back on, make

sure your volume is turned all the way down.

• Never expose this subwoofer to excessive cold,

heat, humidity or direct sunlight.

• This device should never be used in, on or near

water due to risk of fatal shock.

• DO NOT attempt to open or dismantle this

subwoofer.

• These models should always have plenty of air flow

to reduce the chance of over heating.

Subwoofer Placement

This subwoofer is engineered, designed and built to
reproduce low frequencies at and below 150Hz.
Frequencies at this level are basically
omni-directional. This makes it easy to find a good
place for the sub; however, there are also several
location options that can either give more or less
bass. When placed near a wall, you will get louder,
deeper bass. Placing the subwoofer in a corner will
produce a high volume of bass output, while near only
one wall will provide less bass. Placement away from
any wall may not produce enough bass. Because
even a slight change of how the unit sits will alter the
bass output, we suggest trying your subwoofer in
different locations. This will allow you to hear the
difference of bass output and decide what is best for
that particular room and the listener’s preference.

Our suggestion is to place the subwoofer close to the
pair of speakers it will be matched with. For example,
if the subwoofer is to reproduce bass from the front
two channels, then it should be located near the front
two speakers. If it’s to reproduce bass from the rear
effect channels, then the sub should be located near
the rear speakers.built into a

Because Lava Subwoofers are ported from the front,
they can be built into a wall, into cabinetry etc. NOTE:
Even though they are ported from the front, the amp
panel is still located on the back of the subwoofer
cabinet. Proper ventilation is needed for the amp to
"breathe". If the subwoofer will be “built-in”, make sure
there is enough space in the area behind it for proper
air flow. Otherwise, you could overheat and damage
the sub amplifier.

One more NOTE: Because of the acoustics of the
sub installed into an enclosed area, we also suggest
using some kind of sound dampening material in the
space. This will prevent a hollow “boomy” sound
coming from the area behind the subwoofer.

One location or setting will NOT work for all
installations. The ideas above are only suggestions.
Each installation of these products can be different
and you must figure out what works best for your
specific room and system.

Input Connections of the Subwoofer

This subwoofer offers several different “input”
connections allowing it to be compatible with almost all
A/V equipment. The "line level" or "low level" input
connection is usually the best choice when connecting
the subwoofer to a preamp or receiver that has a
subwoofer output connection. The “speaker level" or
"high level" inputs are typically used when connecting
the subwoofer to a preamp or receiver that does not
have subwoofer outputs.

Low Level Input Connections:

Connect an RCA subwoofer cable from the subwoofer
output on the preamp or receiver to the left or right low
level input connection on the rear panel of this
subwoofer. If you need more subwoofer volume, first
make sure the volume knob is turned up. Then, if you
still need more volume, attach a "Y" adapter cable to
the subwoofer cable and then to the right and left low
level input connections on this subwoofer. This will
give another 3 to 6 dB of subwoofer output. Using the
low level input connections requires frequency
adjustments (40 to 200 Hz) to be made with the
frequency knob on the back of this subwoofer.

LFE Input Connection:

Before attempting to utilize the LFE input, consult the
installation manual of your preamp or receiver to
determine if it is set to LFE output. This may not be an
option. It is usually featured on newer surround sound
receivers and preamps. If you proceed, connect an
RCA subwoofer cable from the subwoofer output on
the preamp or receiver to the LFE input connection on
the rear panel of this subwoofer. Using the LFE input
connection requires frequency adjustments to be made
in the menu of the preamp or receiver. The frequency
knob on the back of this subwoofer is disabled under
this setup.

Both low level and LFE input connections should be
made using a good quality RCA subwoofer cable. Try
to keep this cable as short as possible and also try to
avoid running it close to other electrical equipment that
could cause unwanted noise or hum. If the cable is
being installed inside the wall cavity, make sure the
subwoofer cable is kept away from electrical wire.

High Level Input Connections:

To connect your subwoofer with your main right and left
speakers, you will use the high level input connections
on the back of this subwoofer's panel. Locate the right
and left primary speaker connections on the back of
your receiver or amplifier. Connect four good quality

speaker cables from these connections to the high
level inputs on the back of this subwoofer (the black
and red binding posts). Then also connect four
speaker cables from the same connectors on the back
of your receiver or amplifier to the main right and left
speakers. If your receiver has "B” speaker
connections, you can connect your subwoofer to these
connections instead. Using the high level input
connections requires frequency adjustments (40 to 200
Hz) to be made using the frequency knob on the back
of this subwoofer.

Adjusting Subwoofer Settings In Your
Receiver/Preamp

Read the instruction manual for your preamp or
receiver to understand all settings available for
subwoofer adjustments. Go to the “Setup Menu” in the
preamp or receiver. Find the section for subwoofer
adjustments and make sure all the proper settings for
subwoofer outputs are on and set to the correct level
for your application. Different receivers and preamps
will offer different types of features and settings for
subwoofer output.

Digital home theater equipment dedicates one channel
to reproduce the special low-frequency information
contained in digitally encoded soundtracks. Go to the
menu of your receiver or preamp and verify that the
subwoofer output is activated. Having it set this way
