    I've got Cambridge Soundworks S-300 rear surrounds that can be adjusted to direct, bi-pole and di-pole. I'm ready to calibrate the speakers. What do I set the speakers to when I calibrate? If I normally select di-pole for 5.1 movies and calibrate to that setting, what effect would there be when I listen to 5.1 music set to direct, or bi-pole? I assume I have to calibrate the volume to only one selection. Should I chose one and let the others be a compromise, or won't it matter that much? I've not seen this addressed before nor does my Avia disc mention it. Thanks.

    It won't matter whether you calibrate in bipole or dipole modes as the overall output level will not change from mode to mode. Calibrate once and enjoy.

    Johnny, if you switch between direct (for 5.1 music, etc.) and bipole/dipole for movies then you'll need to reset your speaker levels - i.e. recalibrate. I have the S300s and from the listening position there is a db difference between the different modes. What I'd recommend is simply calibrating using each mode and then making a note of the differences. It should be pretty easy to change the volume level when you switch back and forth.

    cheers,
