If the driver taps into the horn at the very beginning it is a standard horn. If it taps in anywhere else along the side it is an offset horn, as the driver is offset from the true throat.

The HR help file explains how to input a BLH pretty well. Where exactly do you fall of the wagon, so to speak?

I have been getting some questions about the AE drivers, and why there is no dimensional info on them.

It's because the info is a pain to get too, as it is not listed with the driver parameters themselves. I when back and added in the easy to find models info. I'll post a picture here, and add a zip file. You can either copy paste from the zip, or manually input them from the pic.

If anyone has the remaining missing parameters please feel free to post them here.

Some HR files

Hi, with the great help of Eazy Horn and Hornresp I calculated some tapped horns. B&C 15SW115, B&C15CL76 (cheap) and Beyma 15G300 8 (because it is laying around) - were tested. The HR files are attached. Interpretation is difficult for me. 15sw115 has already been used for TH and should be the best driver. But it's SPL curve gets ragged even below 200 hz. The Beyma is officially out for a TH, but I see a rather good response up to 400 hz.The boxes are huge ( over 1000 liters), they would be higher than 250 cm. Can someone help me interpret the HR files correctly ? Included is a textfile with some B&C drivers in the format for Eazy Horn, except the columns I did not understand. Some of them could be usable for a TH. To get a smaller box, I think about a 2 x 12" config. But the curves dont look smoother with multiple drives. Why ? Thanks !

It is unclear (to me) how one can build a TH from the HR figures. Starting from the horndata file ( constant depth, with UNI), I exported the radius into Excel : graphically it is an exponential horn, the flare does not matter. No straight borders. I added the first and last radius etc, the resulting enclosure has a marked concave outline. So why not draw a straight line from the throat to the mouth ? Who has been there before ? Thanks.

Hmm, this is the first update email notice I've received in many a moon, so wasn't even aware of the latest revision and don't recall seeing any posts from soho on the forums since then now that I think about it.

Regardless, if he's like me, 'life' is keeping him too busy for much forum time, so glad you were able to work it out on your own.

Yeah, I have taken part in every major data breach pretty much ever. 🙄

Well... except that adultery site anyway. 😉

Oh yeah, and they missed me in the last fed breach. :xfingers:


Life + wife + multiple kids (they just keep popping up) = time?? Nope.
