Professional Series – In-Ceiling Subwoofer
SPECSHEET
Impedance vs. Frequency:
Frequency response (1W, 1 m) is measured on-axis with two boundary junction
(pi loading, gray line) and with three-boundary junction (pi/2 loading, black line)
Frequency Response:
Input connection is conveniently provided on a removable locking
connector (included), providing secure connection via screw-down
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 1/2-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.
