I'll go ahead and sound like a complete "newbie" here, but I can't find any solid answers.
First question - the nominal impedance of the speakers as a whole:
B&W's owner's manual for the 802 M S2 says: "Nominal 8 Ohm, not falling below 4 Ohm." Their manual for the 802 M S3 says: "Nominal 4 Ohm." Yet? My speakers themselves state 8 Ohm right on the back. Anybody have an impedance curve for the system as a whole?
Second question - if I want to biamp? What kind of impedance are we talking for the treble/mid unit, and for the bass bin? Schematics I see show them being in parallel if the system is run with a single amp/cable - which would suggest they are individually at least 8 ohms...
Not really worth talking about what I'm driving them with - they are in my home system, which is nothing special. But? They are quite a nice step up from the 805 Matrix that they have replaced.
