K-Array Truffle KTR26 – Compact High-Output 6.5-Inch Passive Subwoofer

Product Overview

The K-Array Truffle KTR26 is the largest model in the Truffle line of compact passive subwoofers, built for concealed installations that need genuine low-end sustain. This high-output concealable subwoofer pairs a 6.5-inch woofer with a symmetrical passive radiator inside a 12-inch aluminum cylinder weighing only 3.5 kg, delivering 120 dB peak SPL with response down to 45 Hz as an omnidirectional bass source. With 2-ohm nominal impedance and a 100 W rating, it provides the low frequencies for K-Array's Azimut KAMUT2V25 audio system and anchors hidden commercial sound systems in larger conference rooms, auditorium zones, and design-led interiors. Smaller siblings include the Truffle KTR24 and Truffle KTR25.

Product Description

The KTR26 keeps the Truffle formula — an active 6.5-inch driver on one end of an aluminum cylinder, a matching 6.5-inch passive radiator on the other — and scales it to a size that still hides behind seating, inside cabinetry, or above a ceiling line, yet produces 8 dB more peak output than the smallest model in the family. That headroom matters when a concealed system must carry foreground music or program audio with real low-end weight across a larger room. The powder matte black aluminum alloy enclosure measures 182 x 176 x 341 mm, weighs 3.5 kg, and carries an IP64 rating against dust and splashing for semi-exposed placements. The 2-ohm nominal impedance is configured for K-Array amplification, where a dedicated KTR26 preset on Kommander amplifiers such as the KA04 manages crossover, EQ, and protective limiting; any driving amplifier must be rated for 2-ohm loads. In the Azimut KAMUT2V25 system, the KTR26 partners with Vyper line array elements such as the Vyper KV25 II for a full-range system whose components remain effectively invisible. A 2-pin Euroblock connector is included for clean fixed-installation wiring.

Key Features

• Highest Output in the Truffle Line — 120 dB peak SPL with a 100 W rating carries foreground program audio across larger rooms from a concealed source.
• 6.5-Inch Woofer with Passive Radiator — The symmetrical active/passive design extends bass to 45 Hz from a sealed, portless aluminum cylinder.
• Still Concealable at 12 Inches Long — The 182 x 176 x 341 mm, 3.5 kg enclosure hides behind seating, inside cabinetry, or above ceiling lines.
• Omnidirectional Coverage — Even low-frequency radiation keeps placement flexible and forgiving in real interiors.
• 2-Ohm Design for K-Array Amplification — The low-impedance configuration extracts full output from K-Array amplifier channels with the dedicated factory preset.
• IP64-Rated Aluminum Enclosure — The powder matte alloy body tolerates dust and splashing in semi-exposed locations.
• Azimut KAMUT2V25 System Element — The KTR26 supplies the low end for K-Array's Vyper-based concealed sound system.
• Included 2-Pin Euroblock Connector — Phoenix-style screw terminals simplify fixed-installation wiring.

Typical Applications

• Larger conference rooms and boardrooms needing concealed full-weight bass
• Auditoriums and all-hands rooms with hidden distributed subwoofer zones
• Houses of worship reinforcing program audio without visible cabinets
• Commercial meeting spaces and multi-purpose rooms with design-led AV
• Training rooms running Vyper or micro-satellite speaker systems

Frequently Asked Questions

Which amplifier should drive the Truffle KTR26?

The KTR26 is passive with a 2-ohm nominal impedance, so the driving amplifier must be stable into 2-ohm loads. K-Array Kommander amplifiers carry a dedicated KTR26 preset managing crossover, EQ, and limiting; consult Creation Networks for channel pairing on models such as the KA04.

Which speakers pair with the KTR26?

In K-Array's Azimut KAMUT2V25 system, the KTR26 supplies bass for Vyper line array elements such as the Vyper KV25 II; it also matches other compact K-Array mid-highs in custom designs from the K-Array collection.

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

Choose the KTR26 when the room needs low-end sustain: it delivers 120 dB peak versus 112 dB for the KTR24 and 115 dB for the KTR25, in exchange for a longer 341 mm cabinet.

Why does the KTR26 use 2-ohm impedance?

The 2-ohm configuration lets compact K-Array amplifiers deliver the cabinet's full 100 W rating from a single channel, consistent with its role in the Azimut KAMUT2V25 system.

Can the KTR26 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.

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.
