Yep yep. Some people recone perfectly good subs specifically for an ohm load change.

Some will be a lil different spec wise if the motor was optimized for a specific ohm.. so if it was d2 optimized, then a d1 optimized motor would be slightly different if u swapped the coils between (the specs would be diff then a similar motor)

So d2 optimized with a d1 coil wouldn't be the same specs as the same motor in a d1 optimized (if that makes sense)

For ur motor, wont matter though

I believe the AB HD motors are slightly different between D1 and D2 actually.

But thanks for chiming in. Your opinion is duly noted.

I remember the original BTLs were built that way as well, but the difference was so small that it didnt matter

If its a dual one now then dual two should fit as the OD would be smaller. If it was a dual 1 and the gap was optimized for a dual two then the dual one may not fit due to gap clearances.

you assume a lot in your statement here.

what you said, could only be true if the exact same former and material was used to make both coils.

but

most manufacturers only make one size gap for a subwoofer series and they use it universally regardless of impedance or diameter. {D2, D1, D 1/2.... get the same motor gap}

That's why I stated if it was optimized for a two ohm coil. I highly doubt a different sized former would be used. Wouldn't make logical sense to tool different bodys

I mentioned the former because aftermarket coils might not have the same former as original coils.

I agree it doesn't make logical sense, but in the case of AudioQue, that's exactly what they did on some of the HDC3 subs.

Yea, that would need to be taken into consideration if the parts were 3rd party.
