I just had the same problem with the tapped horn feature. Just make it 4 segments instead of 3 and it works again. I like the slide feature. It took me a few tries to get agile, but then it speeded up the process of alignment tremendously.

David, you are updating at an alarming rate!

What more can we expect? I would be interested in a tapped horn alignment wizard (enter length and driver and the wizard sorts out optimal driver position, that sort of thing). But, to be honest, I'm getting pretty good results without it.

It was late, I should have elaboratet more

Excursion of a 2x15" TH looks like this:

So at 60Hz there is a max.

Now using max-SPL feature with 1,8kW and 9,6mm xmax gives:

As far as I understand it, the xmax-feature gives a response curve depending on whether xmax or max power is reached. Input Power here was 1800 Watt, xmax was defindes as 9,6mm.
So if theoratical excursion would be 27mm when driven with 1800 watts, its more than xmax. Therefore xmax should be the limiting factor at 60 Hz. hornresp claims "power limited" though.

Looking at a simulation of a closed design with a different speaker (18") looks like this:

with xmax at 9,8mm and 1250 Watts. The Limitation in the low end is obvious.

Here the sample-feature gives a correct "excursion limited"

FWIW I'm not having this problem, it works with all the old three segment TPs, THs I tried, as well as a couple of new four segment ones, but it doesn't always import the correct 'S2' data in both three or four segment ones, instead some value between 'S1' and 'S2', so of course the response plot is all wrong.

Well, I downloaded it again and re-installed it to see if it would cure my problem, but now I can't view any of my previous three segment TPs, THs, without first adding a 4th section, plus none of the wizard's fields are working right.

Hi Ian,

I should have spent more time on pre-release testing - two obvious errors slipped through :-). The problems have now been rectified. A subtle bug that I discovered recently in the Wavefront Simulator has also been fixed.

Kind regards,

David

Hi Oliver,

You are not missing anything :-).

Thanks for bringing the error to my attention - it has now been fixed.

Product Number 1830-080408 refers.

Kind regards,

David
