to reel from 7 volts or 700 volts is equal to the reel. should rather ask why or why 7 or 700 volts. should be asked how you intend to use the horn driver, you should ask graphs of frequency response and power handling. build a field coil driver is easy , it is not easy calculate voltages, impedances and which trumpets used to equalize the driver .. I do not see any of this work in Kilimanjaro.
I do not understand how we can provide a driver that works in 7 or 115 volts only changing the solenoid, but can not play sounds good in both cases, changing too many parameters.

part of rca driver are like this? : http://voltiaudio.com/midrangedrivers.shtml
