How do I use Hornresp?

[Boscoe]

I have been looking at some TL designs and I'm getting more and more interested in this! Some I've got Hornresp but have no idea how to use it!



I just found this pic on the net as an example! For instance what does the entire half parameters mean? Are they something to do with the enclosure? then I know the bottom half is the driver parameters but I haven't seen all Vrc, Ap, Vtc, Lrc, Lpt and Atc before, what are these?

Okay so once I have put all of these in what doe I do then? Calculate? I enter the Qes and Fs then get something else I don't understand! A diagram of a horn with no markings then the S1, S2... values beneth!

Someone give me a hand, thanks!

Oh yeh and how do I calculate it for two drivers in one enclosure?

Thanks
Boscoe.

Well, realistically you are going to have to do what the rest of have done.

Go through the help file included in the program and then work through (from the begining of the thread) some of the examples given by various DIYers. I would even suggest taking notes that you can refer to. This is a powerful program that will save you from many false starts. It is worth the time & effort.

For TL designs, there is other software that may be more appropriate. Again, use the search fucntion and work through some of the threads. There is no magic 100-word summary.

This might help:

Bassically a standard TL is a rear loaded horn (RLH)with a smaller mouth then throat area. You've simulated a FLH with the mouth and throat area opposite of that of a TL.

Okay thanks, will have a look.

I think I got it wrong tho I think I actually want to make a tapped horn. Like THIS but with an 8" driver. Did I read someone had got a design for an 8"?

Possible?

Well, if you are doing a TH design, the HornResp is perfect. You will need the specs for the speaker (this is a must, don't guess). If it is a new driver, the manufacturer will have these listed.

Please keep in mind that the simulations are sensitive to the loading (2pi space etc). Also keep in mind the other data and not just the freq response (eg, excursion)
