Ron, my personal inclination would have been to stick with a field coil design as you suggested for the exact reasons you suggest.  Terry, the magnetic field is proportional to the product of turn count and .  Double the turn count and you can use half the current.  In any case, I am very appreciative of the input all three of you folks have provided.  While I have the engineering knowledge and experience to know what might be possible, I am lacking in the practical wisdom that you all have provided.  If the cabinet I am considering pans out and my current chassis is functional, I will definitely be looking for more advice.  The idea of other Philco speakers in a similar size had not crossed my mind.

The cabinet (if I take it) will be coming from Alabama to Michigan.  Any recommendations on how to ship it safely and cheaply?

Thanks so much,
TerryMSU

Just to make sure, you chose either 4 ohm into 5K or into 10K? (blk-org or blk-grn)morzh — 06:23 PM
