Dresden, I'm confused-- What is the target low knee? Upper knee? What is the flare rate? Expansion profile? (or T factor -- Hypex, Exponential Tractix, etc). And you want to use one 12" driver? or two in parallel? Or some...

I concur the objective to acquire performance in the desired frequency range must predominate most other considerations of design.My objective for the design of the mid/upper bass horn is to attain effortless, smooth, real-world horn-loaded response ...

You're using a phase plug? Why? To try to get it to go higher? If using parallel drivers, and doubling Sd, it may be necessary to change throat area to not damage drivers... The third design type sounds quite differe...

Happy Holidays, Everyone! First time poster...
Does anyone know where in the US I can purchase a new Electro-Voice DH3 high frequency driver (tweeter) and matching horn (perhaps the HP94--any suggestions?)? I can't find any vendors online that s...

[quote user="Joe Roberts"]The Manger is very different from Lowthers and other paper fullranges. It is very balanced and not peaky at all. Lowthers are lots of fun to experiment with but it seems the Manger is less idiosyncratic sonically, although i...

I once visited a Manger addict who had an active system with Mangers and corner horns (equipped with four eightinchers, not heavy pro stuff). I found the Mangers and the horns very well-matching, and one should be glad about every Watt...

A few questions. What driver is it? It looks like it is 15 Vitavox, is it 151 or 15/40? What the resonant frequency of the horn and driver with no back chamber? The most important: how the hell all of it sound. I do not be believed that you did not h...

I think it might be very interesting to introduce the high-pass filtration for tapped horn and to see how it behaves. It is not only about thermal overload and restriction of excursion. The unloading of none-used bass generally clean-up the transpare...

I have drawn up my 20Hz subwoofer horn in Google SketchUp 3D. This horn is more for home theater than for music. My smaller 40Hz loaded with B&C Speakers 8PE21’s is more musical and articulate. The 20Hz tapped horn is loaded with two Tang Ban...

FWIW, I've done the cone doping myself, and my first reaction to doping paper cones is suspicion. Why does it "need" this, and how/why will it really "help"? But I injected this example only to set it apart from the [Altec] horn doping, r...

[quote user="Paul S"] By the way, Romy, what do you mean by, "As I understand Shakti Soundfield Optimizers teake it way further and I would like to look into it." ? How do these things "work", and what are they taking way further?[/quote] I do no...

There is a picture of a bbq thingy -- at first sight I was confused thinking it was downward & upward facing horns...:)[quote user="Romy the Cat"]

Sorry if this is OT - I could start a new thread but my post is inspired by the quote below - [quote user="drdna"]the lathe-work is rough on some of the horns. [/quote]I can't decide whether that's good or bad. I'm slowly working up to getting ...

Not too many of the cheaper horns have really interested me so far, but I think that we here should help others with this as it could better help them have some horns and horn interest in general. I haven't payed too much attention to much ...

Here's a pic (link) of my listening position.When I built my large Bill Fitzmaurice bass horn...I had thought about placing it in that space above the speakers, firing into the corner. I may still do that...but the sub is serving duties in the separa...

With the height, I plan to have the mid horn set around 1200mm with tweeter below, eg 900mm.
These will reside on a timber or metal stand I'll fabrecate miself.
What are some important considerations here?

If you read Danleys paper, you see that the lower you go in frequency, the more this device turns into a direct radiator. He just vents the HF drivers from the throat, more or less optimised, the midrange drivers a bit further out and the LF drivers ...

Bass horn sub now fitted underneath, with false shelf added for the righ hand side mid bass horn.
The extra height is good....90cm to floor for tweeter, 110cm for the mid horn.
Just a nice BIG wall of sound...wit...

I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also. I was joking with a...

Unluckily I have no experience with IB, would love to. Any way If you want it hidden and time aligned, the best bet is the uderground!Now having all that space there it would be a pity not to go IB.The IB idea can be much more elegant than the pic...

[quote user="ulf"]Let me tell you a bit about how an why we designed the midbass horns the way we did.A few years ago we discovered the tractrix horn for MF use. It was really the most important improvement so far. No more honking exponential horn so...
