pole piece height difference??

[RangerDangerV2 5,000+ posts]

I just bought 2 motors, I bought them as a matched pair, but one of the pole pieces is about an 1/8" higher than the other... Is this a really bad thing? I wouldnt suspect that it would make a difference but this is the first time that I have experienced this problem..

thats strange. depends how far the pole extends. if only .375 then ya .125 is a big diff.

prob got 2 diff batches of subs

put a shorting ring on the top plate and end the eddy current..

Pm me, anyone got input on these? Received them like this, Had no probs when they were built. I'll be calling mmats about this one.

thanks man... I appreciate you calling them, I just wish that you would have told me about the height difference when we were communicating...

Understand man just saw no difference when they were built so didn't think anything of it. Any other builders got input? Can this be fixed?

i thought you ment both poles were extended like most subs 12-18mm from the top plate a shorting ring would have helped.

you cant run these subs together the sub on the right isnt rite at all. there is no sence of having such a thick top plate and not having the pole atleast as tall.

there will be BL and xmax differences between these 2. mmats didnt make these they are dd 9500B's
