4. Product Overview

The Canton AS 225 SC is an active down-firing subwoofer designed to enhance the low-frequency performance of your audio system. It features a robust design and advanced technology for clear and powerful bass reproduction.

Key Features:

• Active subwoofer design for dedicated bass amplification.
• Discreet and modest cabinet design for seamless integration into various environments.
• Solid cabinet construction engineered to reduce unwanted resonance and improve sound clarity.
• Long-excursion woofer with wave technology for extended bass response.
• Down-firing design for efficient bass dispersion and an elegant appearance.

Components:

The subwoofer unit consists of a sturdy enclosure housing a 10-inch aluminum wave surround woofer. The down-firing design means the woofer is positioned at the bottom of the cabinet, directing sound downwards. The rear panel typically includes power input, audio input connections, and control knobs for adjustments such as volume, crossover frequency, and phase.

5. Setup

5.1 Placement

The placement of your subwoofer significantly impacts its sound performance. Experiment with different locations to find the best balance of bass response in your listening area.

• Corner Placement: Placing the subwoofer in a corner often maximizes bass output due to room acoustics, but can sometimes lead to boomy or exaggerated bass.
• Wall Placement: Placing the subwoofer along a wall, but not in a corner, can provide a good balance of output and accuracy.
• Near Main Speakers: Positioning the subwoofer near your main front speakers can improve the blend between the subwoofer and the main speakers.
• Listening Position: For optimal results, consider the "subwoofer crawl" method: place the subwoofer in your primary listening position, then crawl around the room to find where the bass sounds best. Place the subwoofer in that location.

Ensure the subwoofer is placed on a stable, level surface and that its feet are securely positioned to allow the down-firing woofer to operate without obstruction.

5.2 Connections

Before making any connections, ensure the subwoofer and all connected audio components are powered off and unplugged from the wall outlet.

1. Power Connection: Connect the provided power cable to the AC IN port on the subwoofer's rear panel, then plug the other end into a suitable wall outlet.
2. Audio Input:
   • LFE (Low-Frequency Effects) Input: If your AV receiver or processor has a dedicated LFE or Subwoofer Pre-Out, connect a single RCA cable from this output to the LFE input on the subwoofer. This is the most common and recommended connection for home theater systems.
   • Stereo RCA Inputs: If your receiver does not have an LFE output, connect stereo RCA cables from your receiver's pre-out (e.g., "Front Pre-Out" or "Subwoofer Out" if it's a stereo pre-out) to the left and right RCA inputs on the subwoofer.

5.3 Initial Configuration

After connecting, power on your audio system and the subwoofer. Adjust the following settings on the subwoofer's rear panel:

• Volume/Gain: Start with the volume control at its lowest setting. Gradually increase it until the subwoofer's output blends seamlessly with your main speakers. The subwoofer should not overpower the other speakers.
• Crossover Frequency: This control determines the highest frequency the subwoofer will reproduce. Set it based on the low-frequency capabilities of your main speakers. A common starting point is 80 Hz. If your main speakers are small, you might set it higher (e.g., 100-120 Hz). If your receiver has a built-in crossover, it is often best to set the subwoofer's crossover to its maximum setting or bypass it if possible, and let the receiver manage the crossover.
• Phase Control: This control (usually 0° or 180°) helps ensure the subwoofer's sound waves are in sync with your main speakers. Listen to music with strong bass and switch between 0° and 180°. Choose the setting that produces the most impactful and coherent bass.

Refer to your AV receiver's manual for specific setup instructions, especially regarding speaker calibration and bass management settings.

6. Operating

Once properly set up, the Canton AS 225 SC subwoofer operates automatically when your audio system is turned on. Most subwoofers feature an auto-on/standby function that detects an audio signal and powers on the unit, entering standby mode when no signal is present for a period.

• Power On/Off: The subwoofer typically has a main power switch. For daily use, you can leave this switch in the "On" position, allowing the auto-on feature to manage power. For extended periods of non-use, it is recommended to turn off the main power switch and unplug the unit.
• Adjustments: Fine-tune the volume, crossover, and phase controls as needed to suit different audio content or personal preferences. Small adjustments can significantly impact the overall sound.

7. Maintenance

Proper care ensures the longevity and performance of your subwoofer.

• Cleaning: Dust the cabinet regularly with a soft, dry cloth. For stubborn marks, lightly dampen the cloth with water, then wipe dry immediately. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
• Ventilation: Ensure that the ventilation openings are clear of dust and debris.
• Environment: Avoid placing the subwoofer in direct sunlight, near heat sources, or in areas with high humidity.
• Handling: When moving the subwoofer, lift it carefully from the base. Avoid dropping or subjecting it to strong impacts.
