Features

This loudspeaker system delivers high
output, low distortion bass from a small
dual-resonant enclosure and internally-
mounted 18" BWX woofer. It is designed
for portability and includes handles, metal
grill, reinforcing corners, durable carpet
finish and rubber feet. A pole mount is 
included for mounting of a high-pass
enclosure.

Description

The Subcompact 18X is a small,
lightweight add-on subwoofer designed to
make it easy to add more low end to the
SP-X Series or other full-range speaker
systems. Other uses include bass guitar
and drum monitoring.
The enclosure is constructed of 7-ply high
density plywood and MDF, and covered
with a heavy-duty black carpet and
reinforced with polymer corners. A black
metal grill covers the front of the
enclosure. Recessed handles on either
side ease portage.
This low frequency enclosure is comprised
of an 18" BWX Black Widow

®

woofer with

Kevlar

®

impregnated cone, mounted in a

dual-resonant chamber configuration.
This design provides high output and low
distortion by controlling speaker excursion
and acoustically filtering out high
frequencies.
