I'm thinking about starting in on a Weber 5F6A combo, and have been looking over the schematics. Can someone explain why the 4x10 speakers (8 ohm each) are wired in parallel to make a 2 ohm cabinet? The output transformer has taps for 2, 4, and 8 ohms. Is there some reason I shouldn't wire the speakers in series + parallel to make an 8 ohm cabinet and use the 8 ohm tap on the output transformer? Does the tap choice effect the negative feedback circuit? I'd like the flexibility to switch around between various 8 ohm cabinets with the different amps I have.
If folks could recommend some speaker choices too, I'd appreciate the discussion.
