DESCRIPTION
The SP
™
Subcompact 18 is a small,
lightweight add-on subwoofer designed to
make it easy to add more low end to the
SP
™
Series or other full-range speaker
systems. Other uses include bass guitar
and drum monitoring.
The enclosure is constructed of
7-ply 3/4" high density plywood covered
with a heavy-duty black carpet and
reinforced with corners. Black metal
grilles cover the vent openings. A
recessed handle on either side eases
carrying. This low-frequency enclosure is
comprised of an 18" Black Widow woofer
with a Kevlar impregnated cone mounted
in a dual resonant chamber configuration,
providing high output at low distortion by
controlling speaker excursion and
acoustically filtering out high frequencies.
The SP
™
Subcompact 18 now features
a stand adapter which allows any SP
Series enclosure to be used on a (Peavey
part number 00326540) pole. Top cabinet
weight should not exceed 100 lbs. Pole
length should not exceed 36" for other
applications.
