Need help in TH modelling

[killa12222]

I simply can't grasp how HornResp works. I need some help in modeling this driver Dayton SD315-88.

Thanks in advance

Ok, I've finally figured out how HornResp works thanks to the tut above ^^

Here's some screenshots for the Dayton driver





SD compression ratio is 3.37:1. Is it too high?

Comments please

Hi,

I always enter it as a four section model, this provides addditional freedom, and makes it easier to make corrections in the model when you start folding it into an actual enclosure. You can get rid of the big dip @ 100Hz by increasing the driver to mouth distance, and eliminate some of the raggedness in the upper frequencies by shortening L12. The Hornresp Wizard is just an incredible tool.

Also, always take a look at the impulse response of your models.

Ps: double click on the Rms value.

To elaborate on bjorno's suggestion, once the driver's specs are inputted, it's always a good plan to double click on the 'Sd' field to get a pop-up listing of its T/S specs to confirm they are at least close. Right now, yours indicate a driver made from 'unobtanium'.

I didn't know that Rms was clickable

Somewhat! The proof is in the building/measuring, so looking forward to a review.

Hi killa2222,

The Ang @ 0.5 (solid corner placement) coupled w/ the Eg of 2.83V (1W into 8Ohm) gives an optimistically high output. My suggestion would be Ang @ 2.0 and Eg @ 2.0. You don't need the AP1/Lpt fields unless you use a throat chamber (Vtc/Atc).

Overall this looks quite good.

I've got one question, how do you figure out the 3d dimensions of the horn? And, how would i go about folding it?
