Product information

Description

Active tube subwoofer Kruger & Matz LEC-KMI300X, 500W power is a powered low-frequency driver in a cylindrical enclosure designed to reproduce deep bass for car audio systems and mobile sound setups. The active design integrates an internal amplifier so the subwoofer can be connected directly to a head unit or to an existing audio system, providing enhanced low-end response without requiring a separate external amplifier. Its tube enclosure balances enclosure volume and output to emphasize low-frequency extension while remaining compact for easier installation in vehicles or portable rigs.

Advantages

The powered configuration simplifies installation because the internal amplifier is matched to the driver and enclosure, reducing the need for external amplification or complex crossover setup. The tube housing offers efficient acoustic coupling and supports strong low-frequency output relative to its size. Built for vehicle and mobile applications, the design focuses on low-frequency clarity and controlled bass that integrates with midrange and high frequencies from existing speakers.

Suitable for

  • Car audio systems requiring deeper bass reinforcement
  • Mobile sound setups and portable installations
  • Users who prefer a compact, enclosed subwoofer solution
  • Integrating with factory or aftermarket head units

Key specifications

  • Power output: 500 W (RMS/peak values depend on manufacturer specification)
  • Enclosure type: tube / cylindrical active enclosure
  • Amplification: internal powered amplifier (integrated)
  • Application: automotive and mobile audio use
  • Connection types: line-level and speaker-level inputs for integration with head units (check unit for specific connectors)
  • Installation: compact form factor for trunk, cargo area or under-seat placement

How to use

Place the subwoofer in a stable position inside the vehicle or mobile setup where the tube enclosure has enough clearance. Connect the unit to the audio source using the appropriate input (line-level RCA or speaker-level input) and follow the amplifier gain and crossover controls to blend the low-frequency output with the rest of the audio system. Ensure secure mounting and proper wiring, observing vehicle electrical limits and grounding practices. Adjust volume and crossover frequency to achieve balanced bass without distortion.

Usage recommendations

For best results, set the crossover point so the subwoofer covers frequencies below the main speakers' low-frequency capability, typically between 60–120 Hz depending on speaker characteristics. Start with moderate gain and increase gradually to avoid clipping; check connections and vehicle alternator capacity when using the subwoofer at high levels.
