Never before has Klipsch offered such
premium performance in an in-wall speaker.
You’ll discover it delivers effortless dynamic
range and brings superior sound to larger
rooms thanks to its highly regarded THX
Select2 certification.
The KL-6504-THX employs four high-
output 5.25-inch fiberglass woofers for
powerful bass impact, while a 1-inch tita-
nium tweeter mated to a new symmetrical
pattern 90 x 90 square Tractrix® Horn
generates flat in-room frequency response
with high efficiency and low distortion.
This exclusive horn design also allows the
speaker to consistently deliver unbeatable
sound, whether it’s installed horizontally or
vertically.
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.
Adding to its first-class sound, the KL-6504-
THX also has a premium look and feel with
its grille off, featuring a deluxe MDF baffle
with aluminum fascia. But when covered,
the speaker’s paintable grille allows it to
blend in perfectly with any home décor.
All-new sure-grip mounting dogs offer even
pressure against drywall for long-term instal-
lation reliability.
Furthermore, the KL-6504-THX comes with
a lot of options. It is timbre matched to all of
our THX-certified products, so you can mix
and match for the discreet stereo or home
theater system that’s just right for you.
