Adding more Field Coil Speakers, will it whack out the design voltages?
Okay, so I added 2 more identical field coil speakers, and I'm worried it may cause other problems down the road. (See attached schematic)
Rewiring to keep the speaker impedance the same for all four as it was for two was the easy part. But I was unsure how to wire in the field coils. What I did was just connect the two 250 ohm field coil speakers in parallel, and the two 5k ohm field coil speakers in parallel. So, now I assume the 5k circuit now only has 2.5k resistance to ground, and the 250 ohm circuit has only 125 ohms resistance to ground. Being pretty new to this stuff, I'm not really sure what the effect of this is, or if it's going to be a problem down the road. When I tested it, it sounded pretty good. Do you think it will be okay, or what if I added a couple resistors in series to bring the total resistances back to original values?
Thanks
