About the
SPL SUB18
The SPL SUB18 is
an integrated subwoofer and amplifier combination, using
a single 18” long throw driver. It is designed to
provide extended low frequency to enhance existing speaker
systems.
The cabinet is built throughout from premium grade void free
plywood, with extensive bracing to reduce unwanted
coloration, and is painted in multiple textured coats of
catalysed polyurethane.
Although originally designed as a complementary sub bass
cabinet for the SPL12, the SPL SUB18 can easily be used with
other speaker systems. Since its control electronics and
amplifier are built-in, it is the perfect add-on when more
low frequency output is required - for any system!
All that’s required to vary the system setup are some
patch leads and an AC power feed.
Inside
Information
The amplifier
design inside the SPL SUB18 uses existing proven
ARX analog amplifier technology for predictable
operation in all professional applications.
Its transformer based power supply and Mosfet drive
circuitry both enable a reduced parts count for long term
reliability. Plus, with their inbuilt self regulation,
Mosfets are accepted as being the most thermally reliable
and predictable amplifier output stage available.
The 18” bass driver and the output of the amplifier
section are perfectly matched to form a composite unit that
is designed to do only one thing, and do it extremely well.

Other
Features
- L and R mix to mono
built in. With separate inputs and loop through
outputs for Left and Right channels, the SPL SUB18 needs
no special setting up when run in a mono Sub
configuration.
- Phase Switch and
Level control on rear panel for compatibility with
existing systems
- Locking AC power
connectors. By using the Neutrik PowerCon design, the
power connector locks to the cabinet, avoiding the
problem of a connector vibrating loose during a
performance.
- An extra auxiliary AC
power output is fitted as standard, so that systems
can be powered in a serial/daisy chain layout rather than
a radial manner, thus reducing the cabling required. (See
Technical Note SPL Wiring

Benefits
The benefits, both
acoustic and practical, of this amplifier / speaker
combination are many:
- Improved speaker
response. The close-coupled design delivers greater
actual power at the speaker and improves the damping
factor.
- Thermal
reliability. Thanks to our unique heat
exchange/cooling design, the harder the system is driven,
the more efficiently the heat exchanger
operates.
- There is no power
loss caused by long runs of loudpeaker cable -
typically 30 meters (100’) or more. All the
amplifier power is delivered to the speaker.
- An elegant all in one
solution - amp, processor, speaker are combined.
There are no amp racks to store and cool, no heavy
speaker cabling to run.
- Reduced number of
connections contributes to inherent low noise, and
greatly reduces the possibility of ground
loops.
To sum up, the SPL SUB18
successfully combines state of the art design with
practical, proven technology to deliver an integrated
Sub-bass speaker/amplifier solution with all the dynamic Low
Frequency impact that today’s audiences expect.
