Bose speaker compatibility | Bose Music Amplifier

Some speakers are listed as compatible while others with similar ratings are listed incompatible. This is due to variance in resistance at certain frequencies

For Bose and third party speakers not listed, use the following information to determine compatibility:

• Each speaker pair connected to the amplifier requires power handling of 100 W and a minimum nominal impedance of 8 ohms:
• If using a single pair of speakers, each speaker must be 4 ohm minimum
• If using two pairs of speakers, each speaker must be 8 ohm minimum
