Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Controlled Dispersion Technology (CDT): The Klipsch CDT-3650-C
in-ceiling speaker features a patent-pending gimbal mechanism, known as
Controlled Dispersion Technology (CDT). The tweeter and woofer are independently
adjustable, allowing both the high and low frequencies to be directed toward the
High Efficiency: The high-efficiency design of the Klipsch
in-ceiling speakers allows you to get much more output than most in-wall and
in-ceiling speakers. Due to the long speaker wire runs that are common in
whole-house audio systems, the power coming from the amplifier is significantly
reduced by the time it reaches the speakers. The 93dB efficiency of this speaker
means it will play much louder at low power than other less-efficient speakers.
Drivers: The CDT-3650-C is equipped with the following drivers:
- Tweeter: a 1" aluminum dome compression tweeter mated to a swiveling 100° Tractrix
Horn. The swiveling horn design dramatically increases efficiency by
enabling the speaker to produce more output using less energy. The
horn-loaded tweeter allows you to point the sound to a specific location,
and has more controlled directivity than a conventional dome tweeter.
- Woofer: a 6-1/2" copper-colored IMG (injection-molded graphite)
woofer can rotate a full 360°, and then shift 15° in any direction.
Speaker Terminals: The speaker has a pair of spring-loaded binding
posts that can accept up to 12-gauge wire, as well as pin connectors and single
Tweeter Attenuation Switch: If the speaker is installed in an
acoustically bright room, such as a bathroom or a kitchen, you can attenuate the
tweeter by -3dB, using the Tweeter Attenuation Switch, located on the front of the speaker.
Basket/Frame: The CDT-3650-C has a sturdy ABS basket and frame. The
frame can be painted to match any decor (a clear paint mask is supplied to
protect the drivers from overspray). The metal mesh grille is also paintable.
Power Specifications Note: The manufacturer has specified the maximum
power handling of this speaker as 50 watts RMS (200 W Peak). Klipsch has also
published a recommended amplifier power specification as 100 watts. For the
purpose of matching the speaker with the best amplifier, Crutchfield is listing
the power specification as 100 watts.
Installation: The speaker can be installed in new or existing
construction. It requires a cutout diameter of 8.3". For new construction,
purchase of the IK-650-C installation kit (item # 714IK650C) is highly
recommended. For existing construction, the speaker should be installed in
drywall at least 3/8" thick. It can also be installed in a drop ceiling (2' x 2'
or 2' x 4' ceiling tiles only). In both cases, to maximize the acoustic
performance of the in-ceiling speakers, Klipsch recommends you replace the
original mounting panel with 1/2" or 3/4" plywood or MDF. A cardboard template
is included to assist you in making the cutout.
