SPL 18 INTEGRATED SELF POWEREDSUB LOUDSPEAKER SYSTEM

Applications:

Low Frequency enhancement of:� Concert Sound Reinforcement� Auditorium Installations� Dance Clubs� Houses of Worship� Theatre and Film� Corporate A/VFeatures:� Fully integrated amplifier/speaker combination� High power and low distortion provide true sonic accuracy� ISC system protection and CoolPortTM technology� A flexible Sub Bass solution for all applications - just connect a signal and AC power

ABOUT THE SPL18The SPL18 is an integrated bandpasssubwoofer and amplifier combination,using a single 18� long throw driver. Itis designed to provide extended lowfrequency from 35 Hz to 100 Hz toenhance existing speaker systems.The cabinet is built throughout frompremium grade void free plywood, withextensive bracing to reduce unwantedcoloration, and is painted in multipletextured coats of catalysed polyure-thane.Originally designed as a complementa-ry sub bass cabinet for the SPL12, theSPL18 can easily be used with otherspeaker systems. Since its control elec-tronics and amplifier are built-in, theSPL 18 is the perfect add-on whenmore low frequency output is required- for any system!All that�s required to vary the systemsetup are some patch leads and an ACpower feed.

INSIDE INFORMATIONThe all new amplifier design inside theSPL18 uses existing proven analogamplifier technology for predictableoperation in all professional applica-tions.Its transformer based power supplyand Mosfet drive circuitry both enablea reduced parts count for long termreliability. Plus, with their inbuilt selfregulation, Mosfets are accepted asbeing the most thermally reliable andpredictable amplifier output stage avail-able.The 18� bass driver and the output ofthe amplifier section are perfectly

matched to form a composite unit thatis designed to do only one thing, and doit extremely well.

BENEFITSThe benefits, both acoustic and prac-tical, of the amplifier/speaker combi-nation are many:� Improved speaker response. The

close-coupled design deliversgreater actual power at the speakerand improves the damping factor.

� Thermal reliability. Thanks to ourunique heat exchange/cooling de-sign, the harder the system is driven,the more efficiently the heat ex-changer operates.

� There is no power loss caused bylong runs of loudpeaker cable - typi-cally 30 meters (100�) or more. Allthe amplifier power is delivered tothe speaker.

� An elegant all in one solution - amp,processor, speaker are combined.There are no amp racks to store andcool, no heavy speaker cabling torun.

� Reduced number of connections con-tributes to inherent low noise, andgreatly reduces the possibility ofground loops.

OTHER FEATURES� L and R mix to mono built in. With

separate inputs and loop throughoutputs for Left and Right channels,the SPL18 needs no special settingup when run in a mono Sub configu-ration.

� Phase Switch and Level control onrear panel for compatibility withexisting systems

� Locking AC power connectors. Byusing the Neutrik PowerCon de-sign, the power connector locks tothe cabinet, avoiding the problemof a connector vibrating loose dur-ing a performance.

As well, an extra auxiliary AC poweroutput is fitted as standard, so thatsystems can be powered in a serial/daisy chain layout rather than a radialmanner, thus reducing the cabling re-quired.At ARX we have designed the SPLseries to be a true �building block� au-dio system.� It is truly cost effective, with no need

for speaker cabling, extra amplifiersor amp racks.

� The modular concept means totalflexibility, with system inventorykept at the most efficient level. Toincrease or decrease the size of thesystem, simply add or remove cabi-nets as required.

� With a lower parts count than stan-dard systems, and under- stressedcomponents used throughout, me-chanical and electrical reliability isconsistent with world�s best prac-tice.

To sum up, the SPL series successfullycombines state of the art design withpractical, proven technology to deliveran integrated speaker/amplifier solu-tion with all the dynamic impact andtransparent audio that today�s audi-ences expect.
