ButtKicker BK-LFE Low Frequency Effects System

Model: BK-LFE | Brand: Buttkicker

1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of your ButtKicker BK-LFE Low Frequency Effects System. The ButtKicker BK-LFE is a powerful tactile transducer designed to enhance your audio experience by allowing you to feel low-frequency effects, transforming sound into physical sensation.

2. Product Overview

The ButtKicker LFE is a robust haptic transducer engineered for large installations, capable of delivering significant tactile response on various structures such as couches, theater seating, and platforms. Unlike traditional subwoofers that produce audible sound, the ButtKicker LFE operates as a "Silent Subwoofer," converting low-frequency audio signals into vibrations that you can feel. This patented 4-ohm transducer features a magnetically suspended piston, ensuring accurate and powerful frequency response from approximately 5Hz to 200Hz. It is designed for durability and requires minimal maintenance.

5. Setup Instructions

Proper setup is crucial for optimal performance of your ButtKicker BK-LFE system. The unit requires an external power amplifier (not included) to operate.

5.1. Mounting the ButtKicker LFE

  1. Choose a Mounting Location: The ButtKicker LFE is designed to be mounted directly to a rigid structure that you wish to vibrate, such as the frame of a couch, a theater seating riser, or a gaming platform. Ensure the mounting surface is solid and capable of transferring vibrations effectively.
  2. Secure Attachment: Use appropriate hardware (not included) to firmly attach the ButtKicker LFE to the chosen structure. Ensure all mounting points are tight to prevent rattling and maximize vibration transfer.
  3. Isolation (Recommended): For best results and to prevent unwanted vibrations from transferring to the floor or other parts of the room, consider using isolation feet or a floating platform for the furniture or structure the ButtKicker is attached to. This allows the energy to be concentrated where it is intended.

5.2. Connecting to an Amplifier

  1. Amplifier Requirements: The ButtKicker LFE requires a power amplifier capable of delivering between 400 watts (minimum) and 1500 watts (maximum) into a 4-ohm load. Ensure your amplifier meets these specifications.
  2. Wiring: Connect the speaker output terminals of your amplifier to the input terminals of the ButtKicker LFE using high-quality speaker wire. Observe correct polarity (+ to + and - to -).
  3. Audio Source: Connect your audio source (e.g., AV receiver's LFE/subwoofer output, dedicated sound card output) to the input of your power amplifier.
  4. Low-Pass Filter: It is highly recommended to use a low-pass filter on your amplifier or AV receiver to send only low-frequency signals (typically below 200Hz, often 80-120Hz for LFE channels) to the ButtKicker LFE. This optimizes performance and prevents the unit from attempting to reproduce higher frequencies it is not designed for.

6. Operating Instructions

Once properly installed and connected, operating the ButtKicker BK-LFE is straightforward.

  1. Power On: Turn on your audio source and the dedicated power amplifier connected to the ButtKicker LFE.
  2. Adjust Amplifier Gain: Start with the amplifier's gain (volume) control at a low setting. Play audio content with significant low-frequency effects (e.g., a movie scene with explosions, bass-heavy music).
  3. Fine-Tune Intensity: Gradually increase the amplifier's gain until you achieve the desired level of tactile sensation. The goal is to feel the effects without them being overwhelming or distracting. Avoid setting the gain too high, which can lead to "bottoming out" (the piston hitting its limits), indicated by a harsh thumping sound.
  4. System Integration: For home theater setups, balance the ButtKicker's intensity with your audible subwoofer's output for a cohesive experience. Many users find that a slightly lower audible subwoofer level combined with the ButtKicker provides a more immersive and less fatiguing experience.

7. Maintenance

The ButtKicker BK-LFE is designed to be virtually maintenance-free due to its robust construction and patented magnetic suspension system.

8. Troubleshooting

If you experience issues with your ButtKicker BK-LFE, consult the following common troubleshooting steps:

ProblemPossible CauseSolution
No tactile output
  • Amplifier not powered on.
  • Incorrect wiring.
  • No low-frequency signal from source.
  • Amplifier gain too low.
  • Ensure amplifier is plugged in and turned on.
  • Verify all speaker wire connections are secure and correct polarity is observed.
  • Check audio source (e.g., LFE channel settings on AV receiver).
  • Increase amplifier gain gradually.
"Bottoming out" or harsh thumping sound
  • Amplifier gain too high.
  • Lack of proper isolation.
  • High-frequency signals reaching the unit.
  • Reduce amplifier gain.
  • Ensure the mounted structure is isolated from the floor (e.g., using rubber isolation feet).
  • Verify low-pass filter settings on your amplifier or AV receiver are correctly applied (e.g., 80-120Hz cutoff).
Weak or inconsistent vibration
  • Loose mounting.
  • Underpowered amplifier.
  • Structure not rigid enough.
  • Tighten all mounting hardware.
  • Ensure your amplifier meets the minimum 400W requirement.
  • Mount the ButtKicker to a more rigid part of the structure or reinforce the mounting area.
