High Efficiency: The KL-6504-THX's titanium horn-loaded tweeter is mated to the woofers using
precision-voiced high-definition crossover networks creating high sensitivity.
This makes the speaker easier to drive so it requires a lot less amplification
power than conventional designs. The high-efficiency design of the Kirsch
in-wall 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 92dB efficiency of this speaker
means it will play much louder at low power than other less-efficient speakers.
3-Way Speaker Design: The KL-6504-THX uses a premium 1"
Titanium compression driver (tweeter) mated to an exclusive Tracery Horn,
combined with four 5.25" fiberglass woofers in a 3-way design.
- 1" Titanium Tweeter: The KL-6504-THX utilizes a 1" Titanium dome
compression tweeter mated to a 4" square, Tracery Horn, which disperses the
sound 90° horizontally and 90° vertically into the room. The horn design
dramatically increases efficiency by enabling the speaker to produce more
output using less energy.
- Four 5.25" Woofers: The KL-6504-THX employs four
fiberglass woofer cones for powerful bass impact.
ABS Frame/Metal Grille: The KL-6504-THX has a sturdy ABS
frame assembly and a deluxe MDF baffle with brushed aluminum fascia. The frame
and metal mesh grille can be painted to match
Speaker Terminals: The speaker has a gold-plated pair of
spring-loaded binding posts that can accept up to 12-gauge wire, single banana
plugs, or pin connectors.
Power Specifications Note: The manufacturer has specified
the maximum power handling of this speaker as 150 watts RMS (600 W Peak).
Klipsch has also published a recommended amplifier power specification as 200
Dual Orientation: The KL-6504-THX in-wall speaker can be
mounted horizontally or vertically; and can be used as a front, center, or rear
New or Pre-Existing Installation: The in-wall speaker can be
installed in new or existing construction. It requires a cutout diameter of
6.5625" wide x 27.125" high, with a mounting depth of 3.625". A cardboard template is supplied to
measure cutout opening. For existing construction, the speaker should be
installed in drywall (or other mounting surfaces) at least 1/2" thick. The
Kirsch in-wall speaker features eight sure-grip mounting dogs (clamps) that
provide even pressure against drywall for long-term installation reliability.
For new construction, purchase of the IK-504-W installation kit (714IK504W,
sold separately) is highly recommended.
