Hi kahvis,

The Hornresp-predicted results for your proposed design should be okay. The two 90 degree bends are unlikely to significantly affect the 30-120 Hz response.

Kind regards,

David

Hi brsanko,

Your guess is as good as mine... :-).

My "gut feeling" is that the overall combined response performance should not be unduly compromised, but I am not really sure.

Perhaps someone has built such a system, and can comment more authoritatively.

Kind regards,

David

Okay I know this is a tall order but would it be possible to integrate a simple crossover effect into the response graph? Like just click an option that says lowpass, high pass or band pass, and either enter a frequency or use a slider and then maybe a choice between 1st 2nd and 3rd order? Just a thought, I'm doing it in my head fairly easily but it would make it easier to see how say a tapped horn and a rear loaded horn would blend together. I know I"ve made suggestions before and you explained why it wasn't with in the scope of the program and then implemented it six month later anyway so I'll be keeping my fingers crossed. Thanks David you rock!

Hi brsanko,

Sorry, it's not going to happen :-).

Kind regards,

Thanks for the reply.

I have another question about tapped horn. How this kind of tapped horn can be simulated? What about middle fold area/driver's sd ration?

Specify two drivers using the Driver Arrangement tool.
Consider total areas (ie. add the two separate mouth areas together for the purposes of the simulation).

The Sd / S2 compression ratio figure given by Hornresp automatically takes multiple drivers into account.

Kind regards,

Horn segment's areas in the hornresp is all the same, like picture?

Is the simulation result same for these two tapped horns? Only difference in cabinet size and pressure in s2?
Segment areas are same for whole way.

Hi kahvis,

The results will not be the same because of the difference in areas / volumes.

Kind regards,

David

Default Hornresp Update

Hi Everyone,

The Hornresp export horn data tool now has a multiple petal option - 3 to 20 sides can be specified. My thanks to Lars (revintage) for suggesting the feature.

Product Number 2840-110422 refers.

Kind regards,

David
