"

LOW FREQUENCY

SPEAKER SYSTEM

Designed for high output, long-term

reliability, the Klipsch KI-115 low

frequency enclosure utilizes a single

K-48-EP cast frame 15" woofer.

This 95-ounce magnet, 3

"

voice coil

powerhouse delivers high sensitivity

with superior power handling.

Klipsch’s specially designed speaker

motor assembly ensures that high

transient cone excursions won’t

damage the voice coil former under

extreme output applications.

Perfect for music reinforcement and

reproduction, the KI-115 finds ready

application in clubs, theaters,

auditoriums, churches and

performance environments.

The rugged, tuned port, 9-ply

birch enclosure utilizes

CNC fabrication techniques for

uniform tolerances, contributing to

advanced reliability and ruggedness.

Dado “lock-tab” and rabbet joint

construction contribute to

freedom from resonance and

cabinet-induced coloration.

Signal connections are provided via

two parallel-wired Neutrik NL-4

Speakon panel mount jacks.

The KI-115 subwoofer utilizes

radiused top and bottom panels with

a curved perforated metal grille, and

is black dual texture-coated for

weather and corrosion resistance. The

KI-115 is available with or without

a passive crossover, and is compatible

with Klipsch KI-102, KI-172, KI-262

and KI-272 full-range professional

loudspeaker systems.

Like all KI Series speakers, the

KI-115 is covered by the Klipsch

limited five-year warranty.

Architectural Specifications

The KI-115 professional subwoofer shall include a
single 15" (381mm) K-48-EP low-frequency transducer
utilizing a 3" (76.2mm) voice coil and 95-ounce (3.23kg)
magnet.

Frequency response shall be 49Hz to 300Hz, ±4dB,
with the -10dB point at 37Hz, measured at three
meters, half-space anechoic. Refer to graphs for
horizontal and vertical dispersion angles and
directivity. Sensitivity shall be 101dB SPL, measured at
one meter, half-space anechoic, with a 2.83V input.
Power handling shall be 400 watts (46 volts), to AES
standards, continuous pink noise, 40Hz to 10kHz, 6dB
peaks. Calculated maximum continuous output at one
meter shall be 125dB SPL. Nominal impedance shall be
8 ohms, with 5.3 ohms minimum at 42Hz.

Signal connections shall be made via two parallel­wired Neutrik NL-4 Speakon panel mount jacks. The
enclosure panels shall be CNC-fabricated, 18mm,
9-ply birch plywood, assembled utilizing rabbet and
dado joinery. Dimensions for the enclosure shall be

18.438" (46.833cm) high by 19.563" (49.69cm) deep by

24.5" (62.23cm) wide in a

rectangular shape. Net weight

shall be 62 lbs. (28.148kg).

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. The enclosure tuning shall be of a vented design.
The enclosure finish shall be lacquer-based primer and
lacquer-based texture paint with a black finish.

The system shall be a Klipsch KI-115 loudspeaker.
