186 horn in Hornresp

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Does anyone (Rog? ) have the parameters required to simulate the 186 horn in Hornresp? I'm trying to see what the implications would be of reducing the width of the cab by 100mm, but having never used Hornresp before, I'm not sure how to translate the plans into the required parameters.

Cheers,

Wrighty

	i think theres a lot of people who want to know this This is my best guess driver parameters on the net I would say that put vtc as the vol of air in the driver cone area, because it fires directly into the throa, i reckon this is debatable though. ie about 8000cm3 ATC 5cm rear chamber 40-50L average cross section 20cm s1 300 s2 900 s3 1700 s4 4600 if you want to reduce the width by 100mm multiply the above 4 numbers by by 5/6 as the cabinet width is 60cm If you want to learn hornresp check out the sticky thread at the top of the HD15 forum as there are screenshots of the hd15's input parameters. Hope this helps Matt

	Forget to put the horn path lengths double click the L parameters next to the s1,s2 etc to make them say con then enter the following lengths in cm, i modelled it in three sections hence three lengths 30cm 70cm 66cm

	Matt, Thanks for the info. I put the parameters in and I get a plot which looks something like the shape of the one on the plan but at a higher SPL, so I think there's something not right. I'm starting to get the hang of how to use Hornresp now, so if I knew which bit was what when it comes to putting the data into it, I could work out the numbers myself. Can anyone annotate the plan of a horn (eg. the 186 or 1850) showing which parts of the cab correspond with which figures in Hornresp? Cheers, Wrighty

	rog has modelled it in half space ie the top left box you need to keep double clicking until it says 2.0 x Pi can you post up all the parameters for the pd186, i can't find a couple of them on thier website, i'll then see if i can work out how its been modelled matt

	PD.186 parameters for Hornresp: Sd = 1150 Cms = 1.88E-04 Mmd = 184.00 Re = 5.50 BL = 22.94 Rms = 4.05 (Hornresp calculates this if you double-click in the box) Le = guessed at about 1.7mH as there's no published figure. My 186 drivers are at home and I'm at work so I can't measure right now unfortunately :(

	http://img525.imageshack.us/my.php?image=annotated186planwm6.png red lines are s1, s2,s3, s4 and s5 respectively blue lines are the horn section lengths yellow is the throat chamber This is different from what i posted above, can't work out how to do the screen shots on hornresp? I still can't get it to look like rog's though. matt

	Use the PrtScr button on your keyboard, which will put a screenshot on the Windows clipboard, which you can paste into your favourite image editor. From there you can crop it and save it as you wish :)
