K-Array Mugello KS5P I – Dual 21" Passive Subwoofer (Black)

Product Overview

The K-Array Mugello KS5P I is a dual 21-inch passive subwoofer designed for high-output low-frequency reinforcement in auditoriums, houses of worship, and large multi-purpose venues. Cataloged by K-array as the Thunder-KS5P I, this large-format passive subwoofer pairs two long-excursion 21-inch neodymium magnet woofers with a 145 dB maximum SPL rating and response down to 30 Hz. It requires two amplifier channels (2x 4-ohm loads on Speakon NL4), making it a flexible building block for commercial AV subwoofer installation alongside K-array amplifier platforms. For integrators designing a passive subwoofer system with DSP-controlled crossover and networked remote management, the KS5P I delivers touring-grade bass in a serviceable passive cabinet.

Product Description

The KS5P I houses two long-excursion 21-inch neodymium magnet woofers in a polyurea-coated birch plywood enclosure measuring 1140 x 590 x 850 mm and weighing 97.4 kg. Each woofer presents a 4-ohm load and is rated at 2800 W peak, wired through two Speakon NL4 connectors for straightforward two-channel amplification. The crossover is DSP-controlled at the amplifier with a low-pass at 150 Hz, preset dependent, so the cabinet inherits K-array's factory tunings rather than relying on fixed passive networks. The dedicated K-Discovery mobile app gives technicians a user-friendly interface for remote control of the main DSP parameters and signal routing configuration, while K-Framework3 software manages large numbers of units over a wired LAN — a practical capability for multi-zone venue installations and production inventories. The omnidirectional cabinet integrates naturally beneath Mugello line array hangs, and its IP54 rating tolerates demanding environments. This combination of high output, networked management, and a passive amplifier-driven architecture makes the KS5P I a dependable foundation for permanent installs and rental stock alike.

Frequently Asked Questions

How many amplifier channels does the Mugello KS5P I need?

The KS5P I requires two amplifier channels, one per 21-inch woofer, with each section presenting a 4-ohm load rated at 2800 W peak through Speakon NL4 connections.

Where is the crossover handled?

Crossover is DSP-controlled at the amplifier with a low pass at 150 Hz, preset dependent, so the system uses K-array factory tunings rather than fixed passive crossover components inside the cabinet.

How is the subwoofer controlled remotely?

The K-Discovery mobile app provides remote control of the main DSP parameters and signal routing, while K-Framework3 software manages large numbers of units over a wired LAN for demanding multi-unit installations.

Which K-array line array pairs with the KS5P I?

The KS5P I complements the Mugello Series line array elements; the Mugello KH3P I is the matching medium-format element for full-range systems.

Can the KS5P I be used in covered outdoor or harsh environments?

The cabinet carries an IP54 rating; for permanent installation in critical environments such as pools, beaches, or yachts, K-array recommends additional protection and direct consultation on best practices.

What warranty and support apply?
