Platzierung
The placement of the subwoofer significantly impacts its performance. Consider the following:
- Raumakustik: Bass response is heavily influenced by room dimensions and furnishings. Experiment with different locations.
- Eckplatzierung: Placing the subwoofer in a corner often maximizes bass output, but can sometimes lead to boomy sound.
- Wandplatzierung: Placing it along a wall can provide a balanced bass response.
- Hörposition: The ideal placement often involves finding a balance between room acoustics and proximity to the main listening area.

Anpassen der Einstellungen
The R400b features controls to fine-tune its performance to your listening environment and main speakers.
- Lautstärke-/Gain-Regler: Adjust this to match the output level of your main speakers. Start low and gradually increase.
- Übergangsfrequenz: This control determines the highest frequency the subwoofer will reproduce. It should be set to blend seamlessly with your main speakers. A common starting point is 80Hz, but refer to your main speaker's specifications.
- Phasensteuerung: This adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with 0° and 180° settings to find the one that provides the most impactful and coherent bass.

Wartung
Proper care will ensure the longevity and performance of your KEF R400GB subwoofer.
- Reinigung: Use a soft, dry, lint-free cloth to wipe the cabinet. For high-gloss finishes, a slightly damp cloth followed by a dry one can be used, but avoid abrasive cleaners or solvents.
- Abstauben: Regularly dust the unit to prevent accumulation, especially around the drivers and ventilation areas.
- Belüftung: Ensure adequate airflow around the subwoofer. Do not place it in an enclosed cabinet without proper ventilation.
