K-Array Truffle KTR25 – Compact Concealable 5.25-Inch Passive Subwoofer

Product Overview

The K-Array Truffle KTR25 is a compact passive subwoofer that brings deeper, higher-output bass to concealed commercial audio systems while remaining a 10-inch cylinder weighing just 2.5 kg. The mid-size model in the Truffle line, this concealable installation subwoofer pairs a 5.25-inch woofer with a symmetrical passive radiator, delivering 115 dB peak SPL and response down to 45 Hz as an omnidirectional low-end source. It provides the bass for K-Array's Azimut KAMUT2L14 audio system and suits conference rooms, meeting spaces, and design-driven interiors where the subwoofer must stay out of sight. It sits between the smaller Truffle KTR24 and larger Truffle KTR26.

Product Description

Like every Truffle, the KTR25 places a 5.25-inch active driver on one end of an aluminum cylinder and a matching 5.25-inch passive radiator on the other, producing omnidirectional bass that tolerates flexible placement — inside a credenza, behind seating, on a shelf, or above a ceiling line. The step up from the KTR24's 4-inch driver buys 3 dB more peak output and 80 W power handling, which in practice means the KTR25 keeps pace with foreground music in medium-size rooms where the smaller model would run out of headroom. The aluminum alloy enclosure in powder matte black measures 152 x 147 x 258 mm, weighs 2.5 kg, and carries an IP64 rating against dust and splashing for semi-exposed locations. A 2-pin Euroblock connector is included, and the 4-ohm nominal impedance pairs directly with K-Array Kommander amplifiers such as the KA04, whose dedicated Truffle preset manages crossover, EQ, and limiting. In the Azimut KAMUT2L14 system the KTR25 partners with K-Array micro satellites for a full-range concealed system; it also integrates with Lyzard and Vyper elements in custom designs from the K-Array collection.

Frequently Asked Questions

Which amplifier should drive the Truffle KTR25?

The KTR25 is passive and requires an external amplifier with low-pass filtering. K-Array Kommander amplifiers such as the KA04 include a dedicated KTR25 preset that manages crossover, EQ, and limiting automatically.

When should I choose the KTR25 over the KTR24 or KTR26?

Choose the KTR25 for medium rooms where the KTR24 (112 dB peak) lacks headroom but the KTR26 (120 dB, larger cabinet) would be oversized or harder to conceal.

Which speakers pair with the KTR25?

In K-Array's Azimut KAMUT2L14 system, the KTR25 supplies the low end for K-Array micro satellites; it also matches Lyzard, Vyper, and KZ14 elements in custom designs.

Can the KTR25 be placed in damp or dusty locations?

Yes. The sealed aluminum enclosure carries an IP64 rating, tolerating dust and splashing water in semi-exposed placements.

How is the KTR25 wired?

A 2-pin Euroblock (phoenix) connector is included for clean screw-terminal wiring 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.
