Klipsch KI-115 Subwoofer (Each) at Vinyl Sound Toronto Canada

The KI-115 is a professional high-power 15" commercial subwoofer from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Built on decades of Klipsch professional audio engineering, this single low-frequency enclosure houses the K-48-EP cast frame 15" woofer driven by a 104-ounce magnet and 3" voice coil, delivering a sensitivity of 101 dB and a frequency response of 49 Hz to 300 Hz. With peak power handling of 1,600 watts, the KI-115 is engineered for sustained, high-output performance in the most demanding permanent installation environments. It is compatible with Klipsch KI-102, KI-172, KI-262, and KI-272 full-range professional loudspeaker systems and is backed by a Klipsch limited five-year warranty.

K-48-EP Driver and Motor Assembly Technology

At the core of the KI-115 is the K-48-EP cast frame 15" low-frequency transducer, a driver Klipsch engineered specifically for the high-stress demands of commercial reinforcement. The cast aluminum frame provides a rigid, resonance-free foundation that maintains precise cone alignment under extreme excursion. The 104-ounce magnet structure and 3" voice coil are paired with a specially designed motor assembly that controls transient cone movement during peaks in program material. Even at maximum output levels, the voice coil former remains protected from damage, making the KI-115 a reliable long-term investment for venues that operate at full power on a regular basis.

CNC-Fabricated Enclosure and Weather-Resistant Finish

The KI-115 enclosure is constructed from 3/4" furniture-grade plywood using CNC fabrication techniques to maintain tight dimensional tolerances across every cabinet produced. Dado "locktab" and rabbet joint construction lock each panel into position mechanically, eliminating the resonance and cabinet-induced coloration that undermine low-frequency clarity. The tuned reflex port is precisely calibrated to extend bass output cleanly to 49 Hz. Radiused top and bottom panels give the cabinet a refined profile, and the perforated metal grille protects the driver without compromising acoustic output. A black dual texture coating applied to the exterior provides resistance to moisture, weather, and corrosion, making the KI-115 well suited for both indoor permanent installations and environments with variable humidity or temperature conditions.

Frequently Asked Questions

What is the Klipsch KI-115?

The Klipsch KI-115 is a professional passive 15" commercial subwoofer designed for permanent installation in high-output venues. It houses the K-48-EP cast frame woofer with a 104-ounce magnet, delivers 101 dB sensitivity, handles 400 watts continuous and 1,600 watts peak, and produces a frequency response of 49 Hz to 300 Hz. It is part of Klipsch's KI Series professional line, manufactured by Klipsch Group, Inc. based in Indianapolis, Indiana, USA.

How does the Klipsch KI-115 compare to the JBL SRX818S and QSC KS118?

The Klipsch KI-115 is a passive subwoofer optimized for permanent installation, whereas the JBL SRX818S and QSC KS118 are powered portable subwoofers designed primarily for touring and live sound reinforcement. The KI-115 prioritizes long-term reliability and low coloration through its CNC-fabricated plywood enclosure and interlocking joint construction, making it better suited for fixed installations in theaters, houses of worship, and clubs. Integrators who need a passive sub that pairs with an existing amplification system and requires minimal maintenance over years of continuous use will find the KI-115 a more appropriate choice than self-powered touring alternatives.

Can the Klipsch KI-115 be used in outdoor or semi-outdoor installations?

Yes, the Klipsch KI-115 is well suited for semi-outdoor or covered permanent installations. Its black dual texture coating is specifically engineered to resist weather, moisture, and corrosion, making the enclosure more resilient in variable-humidity environments than standard uncoated cabinets. While it is not rated for fully exposed outdoor use, it performs reliably in covered outdoor venues, patios, pavilions, and similar installations where some environmental exposure is expected.

What is the Dado locktab and rabbet joint construction in the KI-115?

Dado locktab and rabbet joint construction is a cabinet-building technique in which panels are mechanically interlocked using precisely routed channels and notches rather than relying solely on adhesive or fasteners. In the KI-115, this joinery method locks each plywood panel into position rigidly, eliminating flex points that cause unwanted resonance and cabinet vibration. The result is a sub-enclosure that contributes no coloration of its own to the reproduced low frequencies, allowing the K-48-EP driver to perform with maximum accuracy.

What amplifier power does the Klipsch KI-115 require?

The Klipsch KI-115 requires an external power amplifier and accepts between 400 watts continuous and 1,600 watts peak into its 8-ohm nominal impedance (minimum 5 ohms at 39 Hz). For typical commercial installation use, a professional amplifier rated at 400 to 800 watts RMS at 8 ohms is recommended. The KI-115's 101 dB sensitivity means it is highly efficient and will produce substantial output even from amplifiers at the lower end of that power range.

Is the Klipsch KI-115 compatible with other Klipsch KI Series loudspeakers?

Yes, the Klipsch KI-115 is designed to integrate directly with the Klipsch KI-102, KI-172, KI-262, and KI-272 full-range professional loudspeaker systems. When ordered with the optional passive crossover, the KI-115 can be used in a passive system configuration alongside these models without requiring an external active crossover or DSP processor. This compatibility makes it straightforward to build a complete Klipsch KI Series system for clubs, theaters, auditoriums, and houses of worship.
