Speaker Placement
Proper speaker placement is crucial for optimal sound performance.

The aperiodic-tuned rear port allows for flexible placement, including against a wall or in open spaces, without significant distortion.

The speaker has an impedance of 8 Ohms.

The speaker also features built-in keyhole slots and threaded inserts for easy wall mounting, providing flexible installation options.
3. Operation
Audio Settings
For optimal performance, especially in a home theater setup, it is recommended to pair the TL1 satellite speakers with a dedicated subwoofer. This speaker is designed to blend seamlessly with a subwoofer, providing a full-range audio experience. Adjust your receiver's crossover frequency settings to around 120Hz for the satellite speakers to ensure proper integration with your subwoofer.
The Time Lens technology ensures that all frequencies reach your ears simultaneously, contributing to superior imaging. The Dynamic Balance technology minimizes distortion, allowing for clear and detailed sound reproduction even at higher volumes.

For the grille, a soft brush or vacuum cleaner with a brush attachment can be used to gently remove dust.
Storage
If storing the speaker for an extended period, keep it in a cool, dry place away from direct sunlight and extreme temperatures. It is advisable to store it in its original packaging to protect it from dust and physical damage.
