I should not even stress more that I do not like people at DIYAudio.com. The domination majority of them incredible idiots and the brightest among them… do not really have any perspective what audio is all about. I do admit that in some seldom cases ...

I am going to show two different simulations for a 105Hz
tractrix horn with the same 8”driver (B&C 8PE21). The parameter values for these two
simulations are quite different. However
the simulations predict the same great flat fre...

Marcus, I have no idea why Jorge assosiated your resonance with your back chamber volume – they are absolutely not related. Why suddenly you start to talk/think about the back chambers is beyond me. Also, I have no idea what the HornResp does at my ...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

Klaus,
Thanks very much for the offer to help.
I have a copy of the latest version of HornResp (and also of WinISP Normal and Pro versions).
To be honest, I haven't yet tried either... Been using my "cousins's" (Jean-Michel Le Cléac'h) Exc...

Rakesh, I have seen your post at DIYAudio, that was a right place to collect group buyers. Still I feel that you did a tactical mistake. You highlighted the fact that the new divers will be identical to the old drivers but in my view you needed inste...

I am currently planning high-WAF speakers for my sister which have to stand in the corners on the floor. Asking for small corner horns I was told the EV Baronet could be a solution. Simulating it with roughly estimated dimensions I found that the FR ...

My 20-50hz TH is not very sensitive. HornResp shows 95db for Ang = 2.0 x Pi.So, it needs power. My 18W GM-70 SET can drive them without clipping, but I prefer to keep amp working at 10% of max power to keep distortions as low as possible, so for TH I...

Hello Romy,I didn't use John Hasquin's tapped horn design, I modeled my own in hornresp for my TAD woofer. I knew I would only need it up to ~55Hz so I was happy to have it flat from 23Hz-70Hz. The lowest crossover point for Behringer DCX 2496 is 20H...

It looks like the hornresp-heads over DIYAudio.com got their Fane Studios and it looks like they like it. Some of them not realize that Fane 8M is sort of DSET Trojan Horns as they will not be able to defeat Fane’s VC inductance with single serial co...

I was simulating the Fane S 8M in hornresp, your favourite program, and then I tried B&C 8PE21 and it was almost identical. Then I tried to simulate the 18Sound 8M400F and it went lower than both of them. Listening tests on youtube comparing the ...

Just looked at the linked picture. Obvious "problems" are varying/variable driver loading and interaction in the "acoustic environment" inside the box and inside the "horn". Like the bumble bee, this "should not fly", for many "fundamental" reasons...

My COVID-19 brain fog has finally lifted. I have been using HORNRESP as the gold standard for horn design. Upon reflection I forgot that we ultimately listen to the sound produced and not the beautiful computer simulated SPL profile. So I ...

I have received some questions and criticism about tapped horns. In order to spread a better understand of tapped horns, I’ll restate the questions and try to answer them.
1.) The mouth of the tapped horn is too small to be useful.
Answer: ...

Dear Malinowski,
Here are the input data used in the HornResp simulation for the tractrix midbass.This is a 117cm long tractrix horn with the TD-1201. Throat area 84 cm2, mouth 10000cm2 with 5,6 liters back cavity.Ang: 1Pi; FTA 89,80; S1 84;...

Hornresp only calculates pressure not tone. That means you can have perfectly flat response and not be able to integrate it with anything.In addition, no single channel can be viewed out of context. They will both change depending on what is below an...

Besides hornresp modeling, is there things to think about when starting design and build of midbass channel from scratch? The range I need is 60 to 300 hz. It will be used with 6db/octave crossover. It will be located under my midrange horn -- the mo...

Murataltuev, I am not qualified to advise about the fine points of horns, per se, but I am guessing the big "slab" in the middle of each horns tower will create more problems than it solves, at least with respect to sound. Honestly, unless you are OK...
