@deboi, esto es lo que pone el manual de mis Bose:
"Setting your digital surround sound receiver Speakers in your Acoustimass® 6 Series III or Acoustimass 10
Series IV system are fully compatible with the audio output of digital surround receivers. The system’s integrated signal
processing supports full low-frequency reproduction from all channels.
To gain complete advantage of these system capabilities, you may want to adjust some settings on your receiver.
To make changes, use the digital display menu on the receiver and refer to the list of recommended settings, below.
Speaker Receiver setting
• Left and right LARGE
• Center LARGE
• Left and right surround LARGE
• LFE/Subwoofer ON
Note: If your receiver provides it, the LFE or Subwoofer option setting should be ON and the crossover value at the lowest number
possible, which is typically 80 Hz"
Debería de poner el LFE en 120Hz? (Se puede seleccionar hasta 250Hz) y cambiar los altavoces a small aunque ponga Large... Ya os decía que los bose se conectan de manera "rara", todos a través de la "caja con especie de sub y electrónica propia para todos los altavoces"....
