STRANGE coil

[dbjunior 10+ year member]

Well I've been looking for a large coil to rebuild my subs,big gap 2.955 pole 3.455 top plate. I found a coil Id 3.00 od 3.434 perfect right. Well here is the weird part its a six layer flatwound dual coil bottom coil 1.4 ohm top coil .7 ohm. How well would this work? I figured I would just wire in series to 2.1 ohm then wire subs together in parallel. Could there be some kind of cancellation if coils were wired in parallel one coil over heating?

no that coil I wouldn't use!

you want a coil that would hit the pole before the winding hitting the top plate. don't use that coil...

Might be a little snug on the outside. Metal expands when heated and coil that is perfectly aligned will begin to rub when you heat it up. One side would get double the current if you parallel.... series or nothing if you want to give it a whirl. Why not just hit up Pierce for some OEM 8 layers? I had really good luck with their coils and never had a problem dealing with them or their recone parts.
