The SSP118-MKII is a high-powered self-amplied single 18-inch subwoofer designed to
give you the low frequency output of an average double 18” in a single 18” box. The SSP118-
MKII features a single 18-inch subwoofer enclosure with a high-powered 2400 Watt Class-D
amplier.
Each SSP118-MKII Powered Subwoofer gives you low frequency output to 30 Hz, typical of an
average double 18”, from a single 18” box. Delivering output to frequencies lower than many
double 18” cabinets, each individualSSP118-MKII enclosure does sowith nearlyhalfthe space and
considerablylessweight.Thisisaverypracticalconsiderationfrombothasizeandcostpointofview.
For Mobile Professionals who provide superior sound quality, the SSP118-MKII allows you to
deliver premium service with less equipment and labor. With two SSP118-MKII Subwoofers,
you will have the output of one of the worlds nest double-18” subwoofers, the BASSBOSS
SSP218, divided into two smaller, more manageable pieces.
Optimized for remarkably deep bass response from a cabinet of mobile size, SSP118-MKII
Subwoofers are each loaded with a single 18” long-excursion, neodymium motor, low
frequency driver. Each driver has a 4” voice coil and is rated for 1500W nominal power handling,
3000W program power handling. It is practically impossible to blow drivers on the SSP118-
MKII, as with all BASSBOSS Subwoofers, due to the combination of extremely rugged, very
high power handling, long excursion drivers, carefully optimized cabinet and port design and
several eective but transparent protection systems. The protection systems prevent thermal
overload of the voice coils and minimize long-term thermal compression while having virtually
no eect on the transient response and peak output of the loudspeakers.
Extremely at, delivering response that is ±3.0dB from 30Hz to 100Hz. No equalization is
required to achieve this response. Unlike designs that require equalization, the SSP118’s tone,
response and sensitivity are native to the design. Systems that require processing to achieve
their stated response are still subject to the physical excursion and thermal limits of their drivers.
Boosting low frequency EQ to achieve extended low-frequency response results in excessive
distortion or woofer damage at full power unless limiting is applied. The limiting necessary to
prevent failure also prevents the realization of their claimed frequency response at full power.
The SSP118-MKII does not suer from these limitations. It faithfully delivers the low bass where
most others either roll o or die trying.
Finished in extremely durable black textured weatherproof polyurethane coating. A top
mounted pole socket in each SSP118-MKII provides for mid-high loudspeakers to be mounted
on a straight speaker pole above the subwoofer. The enclosures also feature four large rubber
feet and corresponding recesses in their tops to facilitate interlocking the boxes when stacked.
The woofers’ cones are made from a waterproof ber matrix which can withstand exposure to
spills and rain and can be wiped clean with a damp cloth.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.
*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specications that are inated over what can actually be
achieved. BASSBOSS real world output specications are provided as “Maximum Sustained Output” ratings, which reect actual measured, continuous output levels.

Setup Instructions:
1. Place loudspeaker in the desired location. Ensure that it is secure and stable.
2. Rotate the input attenuator knob counter-clockwise to the lowest setting.
3. Connect signal from the sound source (mixer) via the XLR female input jack.
4. Connect the XLR male output to the next available loudspeaker input via an XLR cable (if applicable.)
This is a full-range pass-through connection and no processing is applied to this output.
5. Connect the Neutrik PowerCON (blue) connector to the blue power inlet socket. Do not force. To insert, align the
indexing tabs on the connectors, insert the plug fully into the socket and rotate clockwise until the latches catch.
To remove, pull back on the latch tab and rotate the connector counter-clockwise to the index stop, then
pull outwards.
6. Work backwards from the speakers to the outlets, making all PowerCON connections before plugging in to mains power.
7. Connect the electrical plug to a power source.
8. Move the POWER switch to the ON position.
9. Rotate the input attenuator clockwise to achieve the desired sound level.
The integrated DSP includes all the required processing for safe operation and alignment with the accompanying BASSBOSS
top boxes. DO NOT USE third-party outboard processing with BASSBOSS powered loudspeakers. This will not improve, and
will most likely degrade the sound quality and output capacity.
When connecting multiple BASSBOSS loudspeakers in a system, signal can be passed through from one powered
loudspeaker to another using XLR cables. No processing is applied to the signal as it passes through from the input to the
output connectors in each loudspeaker. Signal can be routed in any sequence because each loudspeaker receives a full-
range signal and applies the necessary processing in order to operate as part of the overall system. It is recommended to run
signal to the nearest box rst and patch to the next nearest box in sequence.
When connecting BASSBOSS speakers in a system including other brands of loudspeakers, it’s recommended to connect
the BASSBOSS speakers rst in sequence, then connect other speakers to the pass-through outputs. This ensures that no
inappropriate processing is applied to either loudspeaker.
The typical power draw of one BASSBOSS 2400W amplier module is approximately 5A. With heavy demand, the current
draw can peak at 20A for brief periods but under NEMA code, a 20A breaker should sustain a peak draw of 40A for several
seconds without tripping.
It’s recommended to connect no more than two 2400W amplier to an individual 20A circuit. In situations where circuits
must be shared with other equipment or other brands, it’s recommended to power combinations of a BASSBOSS subwoofer
and a top on a circuit and to power each subwoofer and top combination on a separate circuit to reduce the chances of
overdrawing a circuit and tripping a breaker.

There are 2 control knobs on the amplier.
1: GAIN
Provides attenuation of the input from o to full output. Use appropriate gain structure to ensure the output feeding the subwoofer
doesn’t reach clipping and distortion before maximum desired sound level is achieved. The amplier has a complement of limiters
and safeties to protect itself and the driver however, if audible distortion occurs, lower the level of the incoming signal.
2: EXO ADJUST
This control adjusts the eective crossover frequency allowing the subwoofer to be used with multiple sizes and styles of top boxes
while minimizing out-of-bandwidth noise and phase shift in the crossover region. Rotating the EXO knob fully counter-clockwise
(left) results in an eective crossover frequency of 80Hz. Rotating it fully clockwise (right) results in an eective crossover frequency of
100Hz.
3. CARDIOID SWITCH
Toggle Switch allows selection between NORMAL mode and CARDIOID mode.
With the switch in the NORMAL (up) position, the speaker is in normal operating mode and any number of cabinets can be arrayed
side-by-side facing the same way when they are all in NORMAL mode.
When CARDIOID operation is desired, one or two cabinets must be used in NORMAL mode and at least one cabinet must be placed
in CARDIOID mode and its position reversed relative to the other cabinet(s) The ideal ratio is 2 cabinets in NORMAL with one
CARDIOID cabinet between them vertically or horizontally.
Reduced NORMAL >> Audience
Level << CARDIOID Audience
Area NORMAL >> Audience
The NORMAL mode cabinet(s) are used with the woofer facing towards the audience. The CARDIOID mode cabinet is rotated with
the woofer away from the audience and the CARDIOID SELECT SWITCH in the CARDIOID (down) position.
The cabinet in CARDIOID mode should have the EXO knob at the lowest level, rotated fully counter-clockwise. The EXO setting on
the NORMAL mode cabinet(s) can be set to taste but all cabinets in NORMAL mode should be set the same.
Note: When the speaker is in CARDIOID mode, the green PWR LED is disabled because it will be facing the audience. The speaker
will still power up and play.
When only two cabinets are used, the cabinet in CARDIOID mode can be placed on top of the cabinet in NORMAL mode.
The cabinet in CARDIOID mode can also be placed adjacent to the NORMAL mode cabinet, with the NORMAL mode cabinets placed
farther from the stage or area where reduced level is desired. When only 2 cabinets are in use, the CARDIOID mode cabinet GAIN
should be reduced by 3dB. The greatest level reduction occurs on axis with a line drawn from the center of the NORMAL cabinet’s
bae, through the center of the CARDIOID cabinet’s bae.

If, after following the above instructions for setup, you have no output from the loudspeakers:
Verify that the green power (ON) LED is lit. If not, check the following:
(Note: The ON LED is disabled when CARDIOID mode is selected. To check for power, switch to
NORMAL mode to illuminate the LED)
1. Is the power cord plugged into a live outlet?
2. Is the Neutrik PowerCON connector rotated into the locked position?
3. Is the Power Switch on?
If the green power LED is on, check the following:
1. Is the signal cable connected to the input?
2. Is the signal cable connected to an operating output at the other end?
3. Is the signal owing to the input? Check the integrity of the cable by using a dierent cable.
4. Is the attenuator turned all the way down or at a very low level?
5. Is the signal owing to the input full-range? Filters in the signal may remove the operating
frequencies of the loudspeaker receiving them.

Safety Information:
Important information regarding safety and the use of your loudspeakers:
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable of
causing a sound pressure level detrimental to human health. Seemingly non- critical sound levels (from approx. 95 dB SPL) can
cause hearing damage if people are exposed to it over a long period. To prevent potentially dangerous exposure to high levels of
acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is necessary to wear ear plugs or protective
earphones. See the manual technical specications to know the maximum sound pressure level.
In order to prevent accidents when setting up the loudspeakers or loudspeaker stands, make sure they are standing on a rm
surface.
Ensure that all additional hardware, xings and fasteners used for installation or mobile deployment are of an appropriate size
and load safety factor.
Pay attention to the manufacturers’ instructions and to the relevant safety guidelines.
Regularly check the loudspeaker housings and accessories for visible signs of wear and tear, and replace them when necessary.
Regularly check all load bearing bolts in the mounting devices.
Caution: Loudspeakers produce a static magnetic eld even if they are not connected or are not in use. Therefore make sure when
erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be impaired or damaged
by an external magnetic eld. A distance of 3 feet (1m) should be maintained between loudspeakers and sensitive equipment
such as CRT monitors or magnetic storage media.
Never attempt to carry out any operations, modications or repairs that are not expressly described in this manual.
Contact your dealer or BASSBOSS support if the product is not functioning properly.
BASSBOSS strongly recommends this product be installed by a qualied, professional installer who can ensure correct installation
and certify that it is installed in compliance with the regulations in force.
The entire audio system must comply with the current local standards and regulations regarding electrical systems.
To prevent the occurrence of noise on signal cables, use shielded cables only. Avoid routing signal cables close to equipment that
produces high-intensity electromagnetic elds such as transformers, power cables and loudspeaker wires. Do not coil excess power
cable. Do not coil or wrap power cables and signal cables together.
