HIGH POWERSINGLE 15"
LOW FREQUENCYSPEAKER 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
104-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 underextreme output applications.
Perfect for music reinforcement andreproduction, the KI-115 finds ready
application in clubs, theaters, auditoriums, churches and per-
formance environments. Therugged, tuned port, 3/4" furnituregrade plywood enclosure utilizes
CNC fabrication techniques for unformtolerances, contributing to advanced
reliability and ruggedness. Dado “lock-tab” and rabbet joint construction
contribute to freedom from resonanceand cabinet-induced coloration.
Signal connections are provided viatwo parallel-wired Neutrik NL-4
Speakon panel mount jacks.The KI-115 subwoofer utilizes
radiused top and bottom panels with a 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 Specif icat ionsThe KI-115 professional subwoofer shall include a single 15" (381mm) K-48-EP low-frequency transducerutilizing a 3" (76.2mm) voice coil and 104-ounce(3.23kg) magnet.
Frequency response shall be 49Hz to 300Hz, ±4dB,with the -10dB point at 37Hz, measured at threemeters, half-space anechoic. Refer to graphs for hori-zontal and vertical dispersion angles and directivity.Sensitivity shall be 101dB SPL, measured at one meter,half-space anechoic, with a 2.83V input. Power han-dling shall be 400 watts (46 volts), to AES standards,continuous pink noise, 40Hz to 10kHz, 6dB peaks.Maximum continuous output at one meter shall be125dB SPL. Nominal impedance shall be 8 ohms, with5.3 ohms minimum at 42Hz.
Signal connections shall be made via two parallel-wired Neutrik NL-4 Speakon panel mount jacks. Theenclosure panels shall be CNC-fabricated, 3/4" furni-ture grade plywood, assembled utilizing rabbet and dado joinery. Dimensions for the enclosureshall 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 ametal perforated grille for structural integrity and protection of the transducers from impact and tam-pering. The enclosure tuning shall be of a vented design.The enclosure finish shall be lacquer-based primer andlacquer-based texture paint with a black finish.
The system shall be a Klipsch KI-115 loudspeaker.
