19CS/CST In-Ceiling Subwoofer
Input connection is conveniently provided on a removable
locking connector (included), providing secure connection via
screwdown terminals and allowing a system to be prewired before
installing the speaker for fast snap-on convenience. Separate
connector terminals are available for the input and for the loop-
through wires, making it easy to jumper the speaker signal to
additional speakers. The input terminal plate provides strain relief
for either bare wire, plenum cable or ½ inch conduit (12 mm I.D.).
The terminal box is securely enclosed to meet safety codes.
The speaker trim and grille are paintable to match any decor. A
paint shield is provided for covering the drivers while painting the
rim.
Installation of the Control 19CS is quick and easy. The
loudspeaker is packaged complete with the backcan, grille, support
backing bracket and tile rails.
The entire installation can be accomplished without requiring
access above the ceiling. A template is provided for marking the
cutout. An innovative C-shaped support backing plate can be
installed from below through the cutout to reinforce the top of the
ceiling material. Tile bridge rails are included which can be
screwed onto the C-plate to extend support to the T-channel grid
in suspended ceiling installations. After the speaker is fitted through
the cutout, it is held securely in place via three mounting tabs
which tighten onto the C-plate, if used, or directly onto the ceiling
material.
The Control 19CS backcan is made of formed steel and the
speaker is suitable for use in air handling spaces, per U.L.-2043. An
attachment loop is provided on the backcan for cabling to the
building structure as a secondary support in seismic areas or where
required by code.
The optional Control 19CST version includes a high quality
multitap transformer designed specifically for subwoofer use in
either 70.7V or 100V distributed-line systems. Multiple transformer
taps at 75W, 30W and 15W (plus 7.5W at 70.7V) allow the Control
19CST to fit a wide variety of listening situations. Taps are selected
with a rotary switch conveniently located on the front panel,
protected under the grille, so that the speaker does not have to be
removed to adjust tap settings. The transformer effectively limits the
power to the speaker, so SonicGuard is not included in the Control
19CST.
Frequency response (1W, 1 m) is measured on-axis with two
boundary junction (␲ loading, gray line) and with three-boundary
junction (␲/2 loading, black line)
