4. Setup

4.1 Placement

The center channel speaker is crucial for dialogue clarity in a home theater system. Proper placement ensures optimal sound delivery.

• Central Position: Place the speaker directly above or below your television or projection screen, centered horizontally.
• Ear Level: Ideally, the tweeter should be as close to ear level as possible when seated. The unique reversible design allows you to turn the cabinet upside down to aim the sound upwards if placed below ear level.
• Stable Surface: Ensure the speaker is placed on a stable, flat surface. Attach the included rubber feet to the bottom of the speaker to prevent vibrations and protect surfaces.
• Distance from Wall: While the rear port design delivers powerful bass, avoid placing the speaker directly against a wall, as this can muddy the sound. Allow a few inches of space if possible.

4.2 Connections

Connect the speaker to your audio/video receiver (AVR) using high-quality speaker wire. Ensure correct polarity (+ to + and - to -) for optimal sound reproduction.

1. Identify the speaker terminals on the back of your CS1 speaker and your AVR.
2. Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wire.
3. Twist the bare wire strands tightly.
4. Connect the positive (+) red terminal on the speaker to the positive (+) red center channel output on your AVR.
5. Connect the negative (-) black terminal on the speaker to the negative (-) black center channel output on your AVR.
6. Ensure all connections are secure to prevent short circuits or poor sound quality.

5. Operating Instructions

5.1 Initial Power-Up and Configuration

After connecting your speaker, power on your AVR and follow its on-screen setup instructions. Most modern AVRs include an auto-calibration feature (e.g., Audyssey, MCACC, YPAO) that will automatically detect your speaker, set crossover frequencies, and adjust channel levels and delays for your listening environment.

• Run your AVR's auto-calibration program.
• Verify that the center channel is detected and configured correctly.
• Adjust the center channel level if dialogue sounds too quiet or too loud compared to other channels.

5.2 Recommended Usage

The Polk Audio CS1 Series II is designed for a variety of home entertainment uses:

• Home Theater: Ideal for enhancing dialogue clarity in movies and TV shows.
• Music: Provides clear and accurate vocal reproduction for music listening.
• Gaming: Improves directional audio and voice chat in gaming setups.

For a timbre-matched setup, consider pairing the CS1 with other Polk Monitor Series speakers, such as Monitor 60 or 70 Tower Speakers for larger rooms, or Monitor 40 Bookshelf Speakers for smaller rooms.

6. Maintenance

To maintain the appearance and performance of your Polk Audio CS1 Series II speaker, follow these simple guidelines:

• Cleaning the Cabinet: Use a soft, dry cloth to wipe the cabinet. Avoid using harsh chemicals, abrasive cleaners, or polishes, as these can damage the finish.
• Cleaning the Grille: The detachable grille can be gently vacuumed with a soft brush attachment to remove dust. If necessary, it can be hand-washed with mild soap and water, then allowed to air dry completely before reattaching.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the cabinet finish to fade or warp.
