[Heil Air motion transformer for Cornwalls]

I think that if you're using passive crossover filters, the second figure looks a bit more like a normal impulse response.  If you can plot the step function (the integrated impulse response), you can see this more clearly.

 

Hi @Chris A

 

Those plots above are with no crossover in place. 

 

It's the individual driver plots.

Hi @Chris A @Rudy81and everyone else that's measured their Heil AMTs.

 

Does the impulse response shape of Figure A for my tweeter impulse response look wired in correct polarity? Or is Figure B further below is the correct polarity?

 

Figure A has the sharp negative dip before the peak and Figure B doesn't. I've read on some forums that Heil AMTs are internally wired in reverse so this is confusing to me.

 

I'm colour blind (I can't tell which wire is which colour) so need to rely on measurement to determine 🙂 

 

Thanks in advance

Here is what I get when I reverse the wires:
