I think I am going to design my first horn, play around with hornresp and probably come back with a bunch more questions as I go..

But first thing, I would like to know what difference there is when designing a horn with a single speaker, vs two speakers? If I would like to design a horn using two speakers in-line, how does that enter into hornresp?

Thanks

Use the 'Driver Arrangement' tool.

Thanks Bill, simple enough! Is that available for both tapped and offset horn (like Lilmike's F-20)?

Yes. The links in my sig should help a bit with your design process too.

Yeah I have those bookmarked - I just didn't find anything have to do with two speaker arrangements. Also is there a link somewhere with info on the design of the fold?

Thanks alot guys, appreciate it!

Really? I covered a dual driver design in posts 1 and 2 of the tapped horn tutorial.

I discuss the folding a bit, but honestly, in my case it is all done via trial and error...mostly error.

Ah yes, I jumped the gun. The tapped horn tutorial has alot more information in it, I had only looked at the offset HornResp and quickly glanced at the Tapped horn.. Alot of good info there, I think I have a pretty good idea of how to get started, I'll give it a shot on Hornresp tonight!

Since we're on teh subject, you said trial and error.. does that mean you simply re-draw it several times until everything matches up properly?

Except - I wish it were only several times... Some take dozens.

I scribble ideas with pencil and paper. Lots and lots of scribbling....

When I have an idea that looks like it will work, I draw a scaled 2-dimensional path. When that fits into the space I have available, I adjust the interior panel widths to best load the driver and utilize the available wood. A spreadsheet helps here.

lol, good ol fashioned way... i'm used to that smile.gif

I noticed that in your build with the dual MCM's, you only had 14cm to work with so you would put those side by side to get the compression ratio right.. but did you account the compression ratio for two speakers? Or just one and the same distance woudl work for both?

Ok, so how do I measure a horn fold? Do I just trace the center of the path along the turn?

Thanks
