K-Array Firenze KS7P I – Dual 21" Passive Touring Subwoofer (Black)

Product Overview

The K-Array Firenze KS7P I is a dual 21-inch passive subwoofer engineered for large-scale sound reinforcement, touring systems, and high-output fixed installations in auditoriums and houses of worship. With two 21-inch neodymium magnet woofers, a 146 dB peak SPL rating, and low-frequency extension down to 25 Hz, this passive touring subwoofer anchors the bottom octaves of the Firenze line array system. It is designed for commercial deployment alongside the Kommander-KA208LIVE amplifier platform, whose DSP handles crossover, delay, and frequency shaping for cardioid subwoofer configurations. For integrators specifying a high-output passive subwoofer installation, the KS7P I delivers controlled, distortion-free bass at the most demanding levels.

Product Description

The Firenze KS7P I houses two 21-inch cone drivers with neodymium magnets and 5.31-inch voice coils in a fully closed wooden enclosure. The sealed design ensures consistent back loading on the drivers and eliminates port air turbulence, so low-frequency reproduction stays clean and controlled even at maximum output. The rear panel carries CA-COM IN and CA-COM LINK connections optimized to feed the dual drivers with high power and efficiency from external amplification. Paired with the recommended Kommander-KA208LIVE amplifier, the system gains advanced DSP with up to 2 seconds of input delay and extensive frequency shaping, which makes gradient/cardioid setups and end-fire arrangements straightforward to configure. That processing headroom lets system techs steer bass energy away from stages, altars, and adjacent rooms — a frequent requirement in worship and government venue installations. The KS7P I works as a single point source for focused bass delivery or as part of an arch array, and it couples directly with the Firenze-KH7P I line array element to form a complete high-output touring system.

How the Firenze KS7P I Compares

Frequently Asked Questions

What amplifier should drive the Firenze KS7P I?

K-array recommends the Kommander-KA208LIVE amplifier platform, whose DSP is optimized for the KS7P I and provides crossover, frequency shaping, and up to 2 seconds of input delay for array configurations.

Does the KS7P I have built-in DSP?

No. The KS7P I is a passive cabinet; all processing, including presets and cardioid steering, is handled by the external amplifier platform, which keeps the cabinet lighter and simplifies field service.

Can I build a cardioid subwoofer array with this cabinet?

Yes. Using the KA208LIVE DSP delay and frequency shaping, integrators can configure gradient/cardioid setups and end-fire arrangements to control where low-frequency energy goes in the venue.

Which K-array line array pairs with the KS7P I?

The KS7P I is the low-frequency companion to the Firenze-KH7P I line array element; together with the KA208LIVE amplifier they form a complete full-range touring and installation system.

Is the KS7P I suitable for installation as well as touring?

Yes. The cabinet works as a single point source or in arch array configurations, and its IP53 rating and remote monitoring over Ethernet through the amplifier platform support permanent installations in auditoriums and worship venues.

What warranty covers this subwoofer?

K-array products are covered by the manufacturer's 5-year warranty policy, and Creation Networks assists commercial buyers with system design before purchase and support after deployment.

How heavy is the KS7P I and how is it moved?

The cabinet weighs 98 kg and measures 1162 x 590 x 851 mm, so plan rigging, casters, or a two-person crew for deployment; contact Creation Networks for guidance on transport and installation accessories.
