After experimenting with the frugel horn and then the big Bruce double horn with the FE126E and FE206E drivers respectively and being very imprssed with the results and then wondering why niether of these designs seem to model very well in hornresp my cabinet building friend Doug and I decided to try building a horn design of our own (his actually). After modeling the horn in hornresp he drew it up in Autocad and we started building it(okay I was mainly watching and holding stuff, but I like to think I was very influential in getting him to try it). The speakers came out in my opinion far better than either of the designs we tried previously. True the are extremely boosted from about 65-100hz or so but if you turn the bass down or EQ it flat it is still so much more dynamic in this region that the frugel horns in my livingroom don't sound all that exciting to me anymore by comparison. I'll post the pictures from my phone letme know what you all think http://www.facebook.com/album.php?aid=97087&id=618953972&saved#/album.php?aid=97087&id=618953972

Those look interesting, but most of the links you've posted are asking for a password,
Are you going to post plans?

Are you going to post plans?

The design is actually Doug's so I'll ask him before posting plans. I tried to put the pics as public on facebook but I didn't double check it. if someone knows a better place to post pics from I'm open to suggestions.

I'll definitly post the results when I get some measurements. As far as I'm concerned this design puts to rest all the nay sayers who don't think Hornresp works. These sound exactly like they modeled. lots of bass down to 65-70hz tons of headroom for amazing dynamics, breathtaking dynamics in fact!

Wasn't aware there were any...........
Please post a screen shot of the HR Input Parameters.

Our next project is to add a front horn with response down to 300hz to see if we can bring the volume and dynamics of the midrange and treble up to level of the bass and then a tapped horn to fill in the bottom 2 octives. I designed the tapped horn from a 12" Jensen subwoofer That I got for free (when your straped for cash you gotta work with what you've got) I have also designed a tapped horn for the tang band 6.5" subwoofer that is smaller than the one for the Jensen (less than 1.5 cu ft) and goes down to 30hz @ 125db nice and flat up to 80hz. Can't wait to hear them. I will keep everyone posted I think I'll post those plans on another thread here pretty soon as they are my design.

Like I said it's Doug's design so I gotta check with him first before I post his design and he's probably in bed right now so I don't want to call him. Doug is the bearded gent in the pics.

Hi GM,
"Romy the Cat" doesn't seem to like Hornresp very much 🙂.

Just attach the pics to the forum... some of us believe facebook is a dangerous place to go...

Yeah I think that was the guy I was reading. There some people out there that are conviced that no one can possibly understand anything so we shouldn't even try. I on the other hand thank you very much for this incredible tool and have the utmost faith in it's ability to give me a good idea of what my designs will do before I begin to build them. I am curious thogh to know if hornresp is a good tool to use for prediction of t-line and pipe speakers. I haven't had as much luck using it to predict response of an open baffel but I realize that's not what it was designed for. Although I don't have the correct xmax measurement for the 15" Radio shack drivers I was trying to model. Trying to get information like that from the idiots at radio shack is about as helpful as asking someone at walmart about...well about anything. They are all idiots. that and I don't know how to measure xmax myself.
Hmm. I can't speak for the Frugel-horn, but at this point I suppose I should gently point out that Bruce isn't designed for the 206, so I'm not surprised it didn't look particularly great in Hornresp, or work properly.

Fair enough, I managed to miss the post clarifying this, I was just curious what its response is since you said it sounded like the sim.
OK, the few pics I could view didn't have anybody in them.

Why am I not surprised. He apparently lives in some mental alternate reality where only he understands our physical reality, so I just ignore him. A pity really, the few HE forum posts of his I've read indicated he has a pretty good understanding of audio design theory, but I'm not interested enough to wade through his expletive laced personal attack format responses in the hope of maybe learning something.

I designed a very simple conical front horn to go on this speaker with a mouth area of 500cm and a length of 10cm the throat area is just the front of the driver. Doug built it last night and was very impressed. I haven't heard or seen it yet, but I've been wanting to try a compound horn for a long time now so I'm very anxious to hear it.
BTW if you all haven't figured this out already the driver is the fostex fe126e.

Hi brsanko,
Hornresp can model transmission line and pipe speakers provided that damping material is not included in the design. It can also predict the power response of a driver in an infinite baffle assuming that the diaphragm is a rigid plane piston.
Kind regards,
David
