KPT-745
4-WAY SPACE-SAVING BEHIND THE SCREEN CINEMA SYSTEM
KLIPSCH PROFESSIONAL | CINEMA | DATA SHEET
DESIGNED AND MADE IN THE USA
USING DOMESTIC AND IMPORTED COMPONENTS
In 1946, Paul W Klipsch, genius & maverick, hand-built his first loudspeaker in a
tin shed with the intention of bringing live music into his living room. Remember
great sound? We do, too. Today, Klipsch’s cinema series speaker enclosures are
made in the USA, by proud craftsmen in Hope, Arkansas. Just like PWK intended.

Following the success of the KPT-MCM-II Grand fully horn-loaded, four-way cinema
system, Klipsch desgined the new, four-way KPT-745 to deliver similar movie
chills and thrills but from a much shallower footprint. Less than 24” in depth,
the KPT-745 system is perfect for larger theater venues with limited space
behind the screen.
The low-frequency punch is provided by the high efficiency KPT-415-LF quad
15” bass unit, aided by a separate, single 8”, Tractrix® horn-loaded mid-bass
device, the KPT-305-MB. The KPT-402-MF Tractrix Horn and K-113 2” exit titanium
compression driver effortlessly reproduce the system’s mid frequencies.
For the added kick that’s required by grandiose locations, the KPT-Grand-HF
extended high-frequency horn module easily handles the system’s smooth treble
reproduction. This powerful system is also available with a mid/high passive
processor for a tri-amp and bi-amp configuration.
