Archit ectu ra l S pe ci f ic at io ns

The KI-272 compact, high power, multiple angle loudspeaker
system shall include a 12" (304.8mm) K-42-KP low-frequency
transducer utilizing a 2.5" (63.5mm) voice coil and 77-ounce
(2.18kg) magnet, and a high-frequency K-52-TI 1.5" (38.1mm)
titanium diaphragm 20-ounce (622g) magnet compression
driver mounted on a 60˚ X 40˚ heavy-duty, injection molded
Tractrix Horn. Signal shall be applied to the transducers via a
passive internal frequency-dividing network, incorporating a
KLIP-circuit for signal overload protection of the high­frequency transducer. The enclosure tuning shall be of a
vented design.

Frequency response shall be 67Hz to 12.5kHz, ±4dB, with the

-10dB point at 50Hz, measured at three meters, half-space
anechoic. The high-frequency dispersion angle shall be 60˚
horizontal by 40˚ vertical nominal (refer to graph). Directivity
shall be 9dB (refer to graph). Sensitivity shall be 101dB SPL,
measured at one meter, half-space anechoic, with a 2.83V
input. Power handling shall be 250 watts (41.5 volts), to AES
standards, continuous pink noise, 50Hz to 10kHz, 6dB peaks.
Maximum continuous output at one meter shall be 125dB
SPL. Nominal impedance shall be 8 ohms, with 6.8 ohms
minimum at 180Hz.

The internal passive crossover frequency shall be 1.4kHz, with
slopes of 12dB/octave for the low frequency and 18dB/octave
for the high frequency. The crossover may be modified for bi­amp application by cutting two easy-access internal wires.
Signal connections shall be made via two parallel-wired
Neutrik NL-4 Speakon panel mount jacks.

The enclosure panels shall be CNC-fabricated, 18mm, 13-ply
Baltic Birch void-free plywood, assembled utilizing rabbet
and dado joinery. The motorboard baffle shall be 1" (25.4mm)
11-ply birch plywood. Dimensions for the enclosure shall be
23" (58.42cm) high by 16.5" (41.91cm) deep by 16.813"
(42.705cm) wide in a asymmetrical trapezoidal shape, with
side panels angled at 65˚ and 45˚. Weight shall be 52 lbs.
(23.608kg). The top and bottom panels shall be radiused, with
a curved metal perforated grille for structural integrity and
protection of the transducers from impact and tampering.

Enclosure flying capability shall be provided via 12 internal

3

/8" 16-thread mounting points, three per top, bottom and both

sides, with commercially available rigging bar compatibility.

The enclosure finish shall be lacquer-based primer and
lacquer-based texture, with a black or white finish. The
enclosure shall also be available unfinished in raw birch.

The system shall be a Klipsch KI-272 loudspeaker.

Speaker System

The KI-272 is a high power

loudspeaker solution for limited space

installations, where angled mounting

is required. The speaker is perfect for

angled wall, corner, ceiling or

under-balcony mounting in theaters,

clubs, churches and schools. The

KI-272 also lends itself to slanted floor

or shelf mount use in high power

permanent install or corporate A/V

production environments, where

oblique angle projection is required.

techniques on CNC-fabricated panels

To limit potential damage to the high

KLIP-circuit, a proprietary high-power
