Product Description
The 18SUB is a high output, high definition, passive subwoofer
designed for both portable and fixed installation applications requiring
very high output at the lowest frequencies while maintaining low
distortion. It is part of OEM’s full line of CX Series premium
loudspeakers which are designed to provide unmatched sonic quality
at very high sound pressure levels.
OEM Audio has designed the 18SUB with a high quality 18” long
excursion cast frame woofer with a 4” edge wound high
temperature resistant voice coil. This enables the 18SUB to produce
sustained high levels of low frequency output while efficiently
dissipating heat to improve long term reliability and reduce power
compression. Additionally, the 18SUB woofer has a specially
designed Kevlar reinforced cone which provides consistent sonic
performance when driven at even the highest levels.
Two NL4 connectors are provided for input and loop output which
are mounted into the enclosure’s recessed rear plate.
The 18SUB has an integrated threaded M20 pole plate for solid and
easy installation of top cabinets in full range applications. The
cabinet design of the 18SUB allow for quick and easy transportation
and setup.
The enclosure is made of Void
-
free, multi
-
ply Baltic birch plywood
with optimized bracing to minimize resonances and improve
damping. The 18SUB enclosure provides the strength and
durability needed for a high degree of reliability whether it is used
in portable or fixed installation applications.
Heavy duty, powder
-
coated steel handles are integrated into the sides
of the enclosure at its center of gravity to lower the effort of
transporting and setting up the 18SUB.
The 18SUB addresses a wide range of subwoofer applications from
live sound to commercial installations due to its high reliability and
excellent sonic characteristics. It can be used with any of the CX full
range loudspeaker models to create a variety of complete and
sonically matched sound systems.
