Speaker Impedance Settings
I am running an Onkyo TX-SR703 with B&W DM 604 S3's and a B&W LCR600 S3 center. The speaker instruction manuals say the speakers are 8ohm (3 ohm min). The Onkyo has two speaker impedance settings, 4 and 6. It says use 4 ohms if any speaker is 4 ohms or greater but less than 6, or use 6 if all speakers are between 6 and 16 ohms. I have been running it at the 6 ohm setting but I am wondering if that is the correct one. Also, if either setting is okay, will I get better performance at the 4 ohm setting? Thanks.
