K-Array Mastiff KM112P – Passive Coaxial 12-Inch Stage Monitor

Product Overview

The K-Array Mastiff KM112P is a passive coaxial 12-inch stage monitor designed for stages, broadcast studios, and houses of worship that need high-output, low-profile floor monitoring. The coaxial 12-inch woofer and 2.4-inch compression driver deliver 133 dB peak SPL from a 1200 W, 8-ohm passive design with selectable 30° x 100° or 100° x 30° coverage. As a passive stage monitor for commercial AV installation, it runs on K-Array amplifiers with dedicated presets or daisy-chains from the self-powered Mastiff KM112 for monitor and drum fill systems.

Product Description

The KM112P brings K-Array's Mastiff platform to projects that prefer passive loudspeakers fed from centralized amplification. Its coaxial 12-inch woofer with 2.4-inch compression driver keeps the acoustic center in one point, producing consistent tonal balance for performers who move across the monitor's coverage area. Frequency response spans 70 Hz – 19 kHz with the dedicated preset, and the asymmetrical horn can be oriented for 30° x 100° or 100° x 30° dispersion, letting engineers choose wide near-field coverage for vocalists or a narrower long pattern for drum fill and side fill positions. The low-profile birch wood chassis with stainless steel grille keeps sightlines clean on camera and in architecturally sensitive rooms, and removable rubber feet protect finished stage floors. SpeakON NL4 connectors carry signal in and loop through, simplifying wiring across multiple monitor mixes, and the KM112P can also be driven from the amplified output of a self-powered Mastiff KM112 to expand a monitoring rig without additional rack amplification. Black, white, and custom RAL finishes allow the monitor to match stage design specifications.

Key Features

• Coaxial 12-Inch Driver Design — The 12" woofer and 2.4" compression driver share one acoustic center, keeping tonal balance consistent as performers move on stage.
• 133 dB Peak Output — High SPL capability with 1200 W rated power handling gives monitor engineers headroom for loud stages and drum fill duty.
• Selectable Asymmetrical Coverage — The horn can be set for 30° x 100° or 100° x 30° dispersion, matching wide vocal wedge or narrow fill requirements.
• Low-Profile Stage Footprint — The compact wedge keeps sightlines open for cameras and audiences in broadcast and architectural environments.
• Passive 8-Ohm Design — A single amplifier channel with the dedicated K-Array preset drives the monitor, simplifying centralized amp room layouts.
• Expandable from the KM112 — The KM112P can be driven by the self-powered Mastiff KM112, scaling monitor and drum fill systems without extra rack amplifiers.
• SpeakON NL4 In and Through — Loop-through wiring lets multiple monitors share a mix with clean, road-standard connections.
• Birch Wood and Stainless Steel Build — A sturdy birch chassis with stainless steel grille withstands touring and daily install use, with removable rubber feet for finished floors.

Typical Applications

• House of worship platforms needing low-profile monitoring for worship teams and speakers
• Auditoriums with live performance programs requiring stage wedges and fills
• Broadcast studios where on-camera sightlines demand compact floor monitors
• Multi-purpose rooms and all-hands rooms hosting live presentations and music

Frequently Asked Questions

What amplifier should drive the Mastiff KM112P?

The KM112P is a passive 8-ohm monitor rated at 1200 W. K-Array specifies that passive loudspeakers run with dedicated presets loaded on K-Array amplifiers, so a Kommander amplifier with the KM112P preset is the recommended pairing. It can also be driven from the amplified output of the self-powered Mastiff KM112.

What is the difference between the KM112 and KM112P?

The Mastiff KM112 is the self-powered version with onboard amplification and DSP; the KM112P is the passive version that relies on external amplification. Many systems combine one KM112 driving one or more KM112P units for monitoring and drum fill solutions.

How does the selectable coverage work?

The asymmetrical horn provides 30° x 100° or 100° x 30° dispersion depending on orientation, so the same monitor serves wide near-field vocal positions or narrower throw for fills.

Can the KM112P be used outdoors?

The KM112P carries an IP20 rating, so it is intended for indoor stages and covered platforms rather than exposed outdoor installation.

How does it integrate into a commercial AV system?

As a passive wedge fed from rack amplification, the KM112P drops into monitor buses on any professional console or DSP-based AV system, and K-Array Kommander amplifiers add control system integration and networking on supported models.
