I was pitching before that to make a loudspeaker with integrated LF module you have no ethical right to charge more then let say $20K retail. If you charge more then you have no mechanism to deliver anything for the money people pay. However, if you...

[quote user="jeff1225"]Yes Rommy I agree with most of your comments above. What I found interesting in the larger installation was the time alignment and the bass implementation. I do disagree with your statement of not stopping by to see the Hornfab...

Romy, thank you very much for very detailed explanation of your horn theory.Let me present some doubts about it. From physics basics when we have more than one springs (suspension, throat resistance, back chamber) we can consider it as one spring. Th...

Romy's quotes in blue :"...Discussing the Jessie project we multiple times mention the idea of the large midbass horn hanging above MF section... The rational was to have it positionally contra-react the output of the upperbass horn... But do we au...

I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's high and 125kg's compl...

Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

Paul,
Thanks for the comments.
I may have come up with a way of making the BIG horns fairly painlessly.
I found a place that sells large sheets of urethane foam in several thicknesses and several densities.And, Its no big deal to find a place that...

Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
Interesting, the phase plug-like device...

Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).What sonic aspects in particular? ...

I come up with the idea to introduce 6th channel and add bass array in between tapped horn and upperbass horn. Benefits:1. I can use 1st order lowpass for Tapped Horn at 15-20Hz2. 30Hz+ range become time-aligned3. I don't need to go very low with upp...

Here is an interesting, atypical nowadays, attempt to get 45Hz. With massive (not plywood construction), use one diver instead of two drivers, use better drivers and with proper tuning of the back chamber (it is wrong there) it might be a ...

Hi Romy and all,
first of all, my name is Henry, with a "Y". due to an Irish grand-grand-grand father called "O'Henry". the O' was deleted when my grand-grand father was born, due to a silly servant of registry office. :-) all my horns uses the calc...

Looking at phase 3, one of the first things that pops out is the following:Skushino wrote:"...75-240Hz [from a] 12" x-driver [loaded into a] 70Hz [horn with an] 8" throat..."Because they are a royal PITA to make, you'll want to give yourself every ch...

Romy, i hope this post doesn't offend your sensibilities. I am not gonna say a word about the physics principles that have led me to the conclusion that this is something that should be tried ( unless you ask of course ).
The idea i have is...

[quote user="Romy the Cat"]audiofilofine, you need to form a question in a format that would indicate you do the your do some homework. To bulb or even to design 20Hz horn is complex task and it usually made to the specifics of the given circumstance...

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

[quote user="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]
Yep,...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

I want to share what I feel is a good application of an injection channel, as introduced by Romy. But this is different and also useful and i can tell you it works and very well. Of course, I do not recommend to use this application in the same exact...

I haven't really thought this through, but if I were doing upper-bass horns again, especially if cut using a numerically controlled router, I might consider making tham oval, which would permit going for a horn with a lower cutoff (larger mouth) whil...

We have two models with different upper bass horns, one is indeed a 140hz horn (77 cm diameter) and the original, bigger horn at 110 hz (92 cm diameter) Both tactrix both made from the same materials (MDF) and finished in the same automotive finish.T...

I was rushing when I made the last post. Wanted to share a little more about my thought process and how I arrived at doing another large-scale masochistic audio project. Making a bass horn is a huge risk - the results can vary from exceeding expect...
