MR 33T

2 WAYS REFLEX SPEAKER 40 W WITH TRANSFORMER

DESCRIPTION

Compact design and a wealth of mounting
options make the RCF Monitor 33T a
Compact 2-way loudspeakers ideal for use in
business music systems. The woofer is a high­excursion, carbon fiber design. The mylar
dome tweeter is mounted on a contant
directivity horn to provide natural, smooth
sound reproduction and high resistance to
weather. Installation of the Monitor 33T is fast
and efficient using the accompanying
adjustable mounting bracket. Four M6
threaded inserts add to the speaker's
flexibility. Connections are made to recessed
color-coded, spring-loaded terminals.
Wattage taps, voltage adjustments, and 4­ohm operation are selectable by means of
two detented rotary switches. The enclosure
is constructed of high density, scratch
resistant polystyrene and includes a
protective perforated steel grille and
connection cover.
