Hornresp

Nope no formulas necessary. To enter L12 just click on it till it says Con or Exp then enter the length. As far as the other specs go, just double click on them and it will ask for the information you need.

Sd is the area of the cone. Find the radius(NOT INCLUDING FRAME AND SURROUND) and calculate pi*R/\2

Also, I need to understand how to enter driver parameters.

Specifications: *Power handling: 200 watts RMS/400 watts continuous program *VCdia: 2" *Le: 0.8 mH *Impedance: 8 ohms *Re: 5.1 ohms *Frequency response: 70-4,000 Hz *Fs: 70 Hz *SPL: 97 dB 1W/1m *Vas: 0.6 cu. ft. *Qms: 3.7 *Qes: 0.21 *Qts: 0.20 *Xmax: 6 mm *Dimensions: Overall diameter 8.8", Cutout diameter 7.4", Depth 3.7".

HR needs Sd, Cms, Mmd, Bl, Rms, Nd
Only Re and Le given in above. I guess I need formulas for figuring what HR needs?

Thanks

What driver is it ?

I figured out how to get the driver parameters entered. I found I have some problems with my box measurements I need to fix.

I'm not sure on the type of horn I have (Conical, Exp...)

Based on your drawing, it's a conical tapped horn.

Okay, I fixed the errors and performed a run. Here is what I get:

Let me know if this looks right. I do see the driver is not a perfect match, but doesn't seem too bad. I used same driver in previous post.

Thanks

Correct Vtc to the thickness of wood and Atc to Sd or speaker cut out diameter.

Hi All, I just started using HornResp....Great program David. I am designing 100hz Tractrix horns to match the 250hz tractrix midrange I just build. For that one, I just drew the right sized curve and made the horns. Amazingly, it worked. This time, I am going to use a cone driver instead of the TAD CD so I thought I'd try my hand at modeling it first. SO, is there a tutorial for HornResp? Once I get it figured out, I'll post results. I am hoping to have these built in the next 3 weeks.

Never mind. I just saw Johan's link above. I went 7/8ths of the way through all the post then gave up, just to find what I was looking for at the end. Cheers.
