What is it? An 8086 or XT? 😀
The scanspeak looks pretty smooth. How long until we have the distortion plots? 😉
I recall it is necessary to disconnect the reference channel physically when doing it.pinkmouse said:

Why is that? I would imagine you would want to know only the net speaker distortion, not the distortion of the amp as well.
The CSD on that Scan looks very clean within the first fractions of a millisecond.
The offaxis looks better than other two as well. You could quite easily use a 2nd or maybe even 1st order filter with that as there's no real breakup to speak of.
Nice driver, what vintage is it?

I'd guess it's nineties from the styling, I really know nothing else - even google doesn't help. Have to get some more 12mm mdf to do some mounting plates for the tweets, so that won't be 'till tomorrow now, then we'll see if one of them has a nice roll off to match.

It's been a while since I used that function. So I can't rememberr whether it was just an issue specific to a certain version or whether there was some other reason.y8s said:
Well, after a brief interlude with much strangeness measuring my Tapped horn prototype, it's back to tweeter testing.
Up first, the budget Audax TM020G7. On and off axis FR graph. Look at the very smooth off axis response, this would be great for one of those upward firing omni jobbies.
