1. Posizionamento
The placement of your Kube 12 MIE subwoofer significantly impacts its performance. Experiment with different locations to find the best balance of bass response in your listening area. Consider the following general guidelines:
- Posizionamento ad angolo: Often provides the most bass output due to room gain, but can sometimes sound boomy.
- Posizionamento della parete: Placing the subwoofer along a wall can offer a good balance of output and accuracy.
- In-Room Placement: Positioning the subwoofer away from walls can result in the most accurate bass, though it may require higher volume settings.
The Kube 12 MIE includes a Room Position EQ switch on the rear panel to optimize performance based on its location. Adjust this switch to match your chosen placement:
- Angolo: Select this setting if the subwoofer is placed in a room corner.
- Parete/Mobiletto: Use this setting if the subwoofer is placed against a wall or inside a cabinet.
- In-room: Choose this setting for placement away from walls and corners.

2. Connessioni
The Kube 12 MIE offers flexible connectivity options to integrate with various audio systems:
- Ingresso LFE (RCA): For connection to an AV receiver or processor with a dedicated subwoofer (LFE) output. Use a single RCA cable.
- Line Input (RCA L/R): Per il collegamento a un preamplificatore stereoamplificatore o integrato amplifier with line-level outputs. Use a pair of RCA cables.
- Ingressi livello altoparlante: Per il collegamento ad un amplifier's speaker outputs when line-level outputs are not available. Use speaker wire to connect to the subwoofer's speaker terminals.
- KEF SmartConnect: Questa funzione rileva automaticamente se viene utilizzato un ingresso LFE o di linea e regola di conseguenza la sensibilità di ingresso.

- Risveglio automatico: Il subwoofer si accenderà automaticamente quando viene rilevato un segnale audio e entrerà in modalità standby dopo un periodo di inattività.
- Sempre attivo: Il subwoofer rimane costantemente acceso.
- Innesco 12V: For integration with home automation systems, allowing the subwoofer to be turned on/off via a 12V trigger signal from your AV receiver or processor.

Utilizzo del subwoofer
Once connected and powered on, you can fine-tune the subwoofer's performance using the controls on the rear panel:
- Controllo del volume: Regola il livello di uscita complessivo del subwoofer. Inizia con un'impostazione bassa e aumentala gradualmente fino a quando i bassi non si fondono perfettamente con gli altoparlanti principali.
- Frequenza di crossover: Determines the highest frequency the subwoofer will reproduce. This should typically be set to complement the low-frequency capabilities of your main speakers. A common starting point is 80Hz.
- Controllo di fase: 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 coherent and impactful bass.
