K-Array Truffle KTR24 – Ultra-Compact Concealable Passive Subwoofer

Product Overview

The K-Array Truffle KTR24 is an ultra-compact passive subwoofer designed to deliver controlled low-frequency reinforcement from a cylindrical aluminum enclosure just 8 inches long and 1.5 kg in weight. The smallest model in the Truffle line, this concealable installation subwoofer pairs a 4-inch woofer with a passive radiator to reach 112 dB peak SPL with response down to 45 Hz, acting as an omnidirectional low-end source that hides in millwork, shelving, or under furniture. It provides the bass for K-Array's Azimut KAMUT2L1 audio system and complements micro satellites in huddle rooms, conference rooms, and discreet commercial AV designs.

Product Description

The Truffle concept is simple: an active driver on one end of a small cylinder, a symmetrical passive radiator on the other, producing omnidirectional bass that is forgiving of placement — tuck it behind a planter, inside a credenza, or above a ceiling line and the room still receives even low-frequency energy. The KTR24's aluminum alloy enclosure in powder matte black weighs only 1.5 kg and measures 122 x 117 x 199 mm, making it one of the easiest subwoofers to conceal in any commercial interior. An IP64 rating allows placement in damp or dusty locations, and the included 2-pin Euroblock connector keeps wiring clean in fixed installations. With 4-ohm nominal impedance and a 60 W rating, the KTR24 matches naturally with K-Array Kommander amplifiers such as the KA04, whose dedicated Truffle preset manages crossover, EQ, and limiting. In the Azimut KAMUT2L1 system it partners with Lyzard micro speakers for a full-range system whose largest element is an 8-inch cylinder. When a room needs more output, step up to the Truffle KTR25 or Truffle KTR26.

Frequently Asked Questions

Which amplifier should drive the Truffle KTR24?

The KTR24 is passive and needs an external amplifier with low-pass filtering. K-Array Kommander amplifiers such as the KA04 include a dedicated KTR24 preset that manages crossover, EQ, and limiting automatically.

Which speakers pair with the KTR24?

In K-Array's Azimut KAMUT2L1 system, the KTR24 supplies bass for Lyzard micro speakers. It also works alongside Vyper and KZ14 satellites in custom small-room designs; see the K-Array collection.

How do I choose between the KTR24, KTR25, and KTR26?

Choose by room size and output need: the KTR24 (112 dB peak) handles small rooms and zones, the KTR25 (115 dB) covers medium rooms, and the KTR26 (120 dB) serves larger spaces requiring low-end sustain.

Can the KTR24 be placed in damp or dusty locations?

Yes. The sealed aluminum enclosure carries an IP64 rating, tolerating dust ingress and splashing water in semi-exposed placements such as covered patios and back-of-house areas.

How is the KTR24 wired?

A 2-pin Euroblock (phoenix) connector is included, giving installers clean screw-terminal wiring for fixed installations at 4-ohm nominal impedance.

What warranty applies?

K-Array products carry a 5-year manufacturer warranty, supported by Creation Networks as an authorized dealer with commercial AV design assistance.
