As I learned today the Australian Martin seddon know as the Azurahorn Guy has a web site and he also does horns:

Hi Romy,Its an Altec 416-8A driver in a ~100 Hz exponential horn, Jbl 2441 in 350Hz tractix, Aurum Cantus G1 tweeter and Eminence Definimax 4012 HO in ~30Hz Tapped horn.I just hooked it up and the highs are promising but I thought the lower end (200 ...

[quote user="Romy the Cat"]I woke up and thinking about the horn problem with fresh head I am thinking what did wrong. I did not measure the frequency response of the horn – I did not see a need for it – the sound of the thing is way beyond where it ...

Of course I am not really talking about Rullit but only holding up his implimentations against his stated aims. This is certainly no special case, since most smart people learn the talk and the "look" long before they learn practicum, if they ever d...

Romy, Looking at your cartoon again, I wonder if you are showing manufactured trusses inside the horns?If not, what does the shading that looks like trusses mean to show?If so, your carpenters are either very good, very optimistic or very hungry.Are ...

[quote user="jessie.dazzle"]From this and from the mention of 3/4" plywood, I deduce that the "curved" walls of these horns will likely be described by a series of facets (flat planes). It is said to be okay at these frequencies; this must assume a p...

It is 4” exit and reportedly goes down to 27Hz. I do not know what a lot about this diver but it might be a good driver for 40Hz horn. 4” into 40hz? God, it has to be at least 16 feet long horn! I would take my head off to somebody who goes for it. A...

Hi thereFor some time its bugging me that compression drivers got a very heavy but odd load of air coupling on the membrane. I saw a scatch here to put ideally 2 Horns on each side of the driveway to balance it. That's obviously not so economically :...

So, with this horn I got the sound I was dreaming for!Currently system consists of 4 channels:1. RAAL Lazy Ribbon (14k+)2. JBL 2453 in 550Hz LeCleach (1200 - 14k)3. JBL 2490 in first part of own JBL horn (300-1200)4. 12" Supravox in 42Hz 2m long horn...

Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the le...

Completely understandable. That's why it's fun! It's enjoyable to make something, study the results, make changes, and start over! That seems to definitely be the theme with horns from what you guys are telling me.So it sounds like I shouldn't expe...

The horns are still plugged but I desired to test if the vibration from the midbass hors will be detectable on the listing room floor. The mouth of the horns does vibrate. Well, it is not a vibration but rather some shaking – pit in this way – if I h...

It is depends what kind horn it is. For LF horn the resonance should not be “an octave lower then lowest frequency you can realistically get from the horn”. In fact the common way is to much the assembly resonance to the horn cut off by squashi...

Allo fellas,
Regarding pricing, best if you check with Martin; I know what I'm paying but I had to commission them specially - I know a hell of a lot of work went into making the mould, jigs to support the mould, etc etc. Actually the 340s were my c...

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

Generally, I do not think it is possible to put 60Hz horn under MF channel. You have a limited highs of MF and you need to put 60Hz under it. You have no room for circular horn and you have to go rectangular, mach wider then you want it to be. Then ...

As I reported at GSC, my CD transport started acting up (skipping) quite a while ago, at a time when I was unable to deal with it. I thought at first I had ruined several CDs by playing them in my car, but that turned out to be a coincidence. When I ...

Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...

Yes, too low efficiency, even worse than Altec 515, (when loaded with small throat, in proper FLH, NOT A7 type "horn" which disqualified it also for my usage... I don't know how "colored" Tannoy would sound with properly designed...

KlausMartin (Azura horn ) is making for me extension to 2.75" (BC 8p21)and 1.4" for 204 Hz (altec 288c) .He also developed 550 hz horn for S2 . He understands importance of smooth driver -throat transition . It would be ready to go solution for...

Hi Romy, I ended up using a TAD 1101h 11 inch driver, 97db, 38fs, and is what I believe a stronger cone than the Goto 8 inch. The DIY mid bass horn is a 1/2 space 53hz hyperbolic horn with 5in x 5in square throat. Length is about 8'6", height of mout...

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]

Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the acoustical length of ...
