Safety Information
Please read and understand all safety instructions before operating the Aguilar SL1108 Bass Cabinet. Retain this manual for future reference.
- Power Source: This is a passive speaker cabinet and does not require direct AC power. It must be connected to a suitable bass amplifier.
- Ventilation: Ensure adequate airflow around the cabinet. Do not block ventilation openings.
- Moisture: Do not expose the cabinet to rain, moisture, dripping, or splashing liquids.
- Heat: Keep the cabinet away from heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat.
- Connections: Always use high-quality speaker cables for connections. Ensure proper impedance matching between the amplifier and the cabinet (8 ohms).

Setup
Proper setup ensures optimal performance and longevity of your SL1108 Bass Cabinet.
- Placement: Position the SL1108 cabinet on a stable, flat surface. For best sound projection, place it on the floor or on a sturdy speaker stand. Avoid placing it directly against walls or in corners, which can sometimes lead to excessive bass resonance.
- Connecting to an Amplifier: Use a high-quality speaker cable (not an instrument cable) with 6.35mm (1/4-inch) TS connectors. Connect one end of the speaker cable to the speaker output of your bass amplifier and the other end to the input jack on the rear panel of the SL1108 cabinet.
- Impedance Matching: The SL1108 cabinet has an impedance of 8 ohms. Ensure that your bass amplifier's speaker output is set to 8 ohms, or that the total impedance of all connected cabinets matches the amplifier's recommended load. Incorrect impedance matching can damage your amplifier or cabinet.

Operating Instructions
The SL1108 is a passive cabinet, meaning its operation is primarily controlled by the connected bass amplifier.
- Power On Sequence: After connecting the SL1108 to your amplifier, ensure all volume controls on your amplifier are set to minimum before powering on the amplifier.
- Adjusting Volume and Tone: Use the controls on your bass amplifier to adjust the overall volume, bass, midrange, and treble settings. The SL1108 will accurately reproduce the sound shaped by your amplifier.
- Monitoring Sound: Listen carefully to the sound output. If you hear any distortion or unusual noises, reduce the amplifier's volume immediately and check all connections and settings.
- Power Off Sequence: When finished, turn down the amplifier's volume before powering off the amplifier. This helps prevent sudden pops or surges that could stress the speaker.
Maintenance
Regular maintenance helps preserve the appearance and performance of your SL1108 Bass Cabinet.
- Cleaning: Use a soft, dry cloth to wipe down the cabinet's exterior. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Storage: When not in use, store the cabinet in a dry, temperate environment, away from direct sunlight or extreme temperature fluctuations.
- Inspection: Periodically inspect the speaker grille for any damage and ensure all hardware (corners, handle) is secure. Check speaker cables for wear or damage.
