Hey guys. I've got an 8 inch KEF sub driver just lying around and I decide I am gonna build a tapped horn with it. Since there's no description / model or anything, I measured it myself using ARTA/LIMP; here are the parameters:
So, here's the deal.. I've played around with Hornresp before, but I've never actually built anything based on it. That's why I read and tried to follow Lilmike's excellent guide, but there are some thing that are unclear to me, mostly about the way Hornresp implements the data you feed into it.. let me post some screens from Hornresp:
Hornresp / driver parameters:
Acoustical response without power / xmax input:
Response with 60W / 4mm xmax input:
Displacement at 1W vs 60W / 4 mm xmax
So, there are a couple of things that I am worried about; first off, does everything look normal to you in the parameters and simulations?
Is it normal to have a much flatter response at 1W than it is with added power? Looks much too lumpy to me at 60W.. 11dB of difference between the highest and lowest spike.
And lastly, the displacement simulation at 60W looks awful, pretty sure something is wrong with it.
So, that's pretty much all I am concerned about; Hornresp is a beautiful piece of software and I do look forward to learning how to utilize it in the best way possible. I just want to have everything straight theory-wise, before I even start exploring ways to fold it so that there's still space for me in the room
Thanks in advance
