Congratulations on your selection of the SW1801 Sub Woofer
System. The SW1801 is the finest single 18” sub-woofer enclosure
that Carvin has ever offered. Perfect for bands, DJ’s, and
permanent installations. From tight, punchy upper-bass to earth
shaking sub-bass, the SW1801 can fulfill any professional sound
reinforcement requirement easily. The built-in sub woofer crossover
does an excellent job eliminating all upper frequencies (can be
switched out for bi-amping or tri-amping directly to the drivers).
Compatibility with any amp is assured with high current Twist-Lok™
twist-on connectors and standard 1/4” phone jacks.

SPEAKER CABLES
Use either 1/4” 16 gauge copper wire speaker cable or high-current Twist-Lok™
cables with heavy 4 conductor 12 gauge copper wire. The Carvin PH50 is
adequate for lengths up to 50’ under normal use. You can DAISY-CHAIN up to one
additional speaker per cable by using the OUTPUT connector. Be sure to note the
total impedance to the amp so it is not lower than it’s recommended impedance.

SUGGESTIONS FOR OPTIMAL PERFORMANCE
It is recommended to keep subwoofers on the floor as the floor enhances the
low frequency wave to develop more acoustic output. Subwoofers may be hung
but their efficiency is slightly lower when suspended.
