[quote user="Rewind"]You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde...

Skushino. Yes TH is designed to play 2 octaves and no more, this derives from the design which actually uses a labrynth, in the shape of a horn, to return (and amplify) the back wave of the driver to the front and add its strenght to the output, no...

I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression drivers I tried. That is wha...

[quote user="de charlus"]It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound...

Charlus, it is not about an expression of gratitude, trust me, I am very indifferent neither to criticism or appreciation. Ironically what you are trying to do is in a way an organic holding a touch of a few audio ideas that I happened to advocate as...

Had a wonderful visit with my Japanese friend. But now she's flying West over the Pacific, and I wanted to add my experience to the TH discussion.The main benefit of the TH is the relatively small mouth compared with a traditional horn. That's all....

INTEGRATION that's the clue and that's what I always feel lacks in my room, I mean extreme integration, real integration, the feeling that the recorded bass sound has its own boundaries, not my room's. So you said, midbass horns?OK, let's g...

I was thinking and thinking last couple days what to do with
my lower midbass situation. I do need to use 2 drivers per channel with 100dB efficiency
to get the dBs I need to match Macondo and Milq’s bass channel gain. I do want to use Vitavox 15”...

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 ...

There are very many totally not predictable things in bass horns; I would not go into enumeration of them – what the point? However, keeping the thread in context if it’s subject I would note that the objectives and reference points of the horn owner...

Thanks Johan, I got my SG505's and S150 horns, my throat piece is a lot longer than the one you showed above. Why can't they just sell that little screw... along with lots of other "why can't they"...Anyway, I just reread this thread and I can m...

Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret wither the woofer will be go...

Romy,
I am off to Taiwan tomorrow but will ask the question by email. I have not heard that kind of custom diaphragm ever available from GOTO on SG146LD4 driver. I know the 15" woofer can be request with different stiffness of the cone.&...

Last night I spent some time with observing my ULF and I conclude that I am not exactly know what I deal with. Do not get me wrong: the ULF forks fine, sounds fine and the playback is perfectly operational and listenable; it does sound very good ...

I was thinking and fantasizing about finishing of my midbass horn. My first idea was to paint it internally with the same color as my cathedral room. Perhaps a lighter grade of paint in the end as the horn goes dark. As the only mouths of the horns w...

Excellent news regarding this morning's discoveries. jd wrote:"...Are you able to say whether the problem is due to the horn position relative to the room, or to throat diameter relative to the driver diameter?..."Yes, a stupidly phrased question, bu...

[quote user="js"]Could anyone please advise me as to the recommended rear chamber volume for a Le C'leach horn with a throat of 240cm2, mouth of 7089cm2, length of 47cm, cutoff of 160Hz, T of 0.8? I'm thinking of using a Beyma 122Nd which has a sd o...

I had a Behringer DCX2496 that used for nothing and I think it got broken. I do not want to by another one. What I looking for is some kind cheap, no more than $100 solution that would allow be to have 4 order filters and crossover point up to 250hz...

Herman,Im sure you are right about what you are saying and it makes perfect sense. In the Valencia though, the 416 was crossed over at 800Hz to an even smaller(1") compression driver and to me it sounded really good. The reason I chose a 15" in the f...

Hi Romy,
I've confirmed through Goto's Japanese dealer that a drop between 200-400hz is normal for 505TT, their suggestion was to double up on drivers or buy the more expensive versions... Looking at the measurements the 505TT is good for 400-1800...

I'm not sure I understand what point you consider a priority, but I can explain the reason for my initial inquiry and what I intend to do.My initial inquiry was intended to acquire information on whether a horn with a target range of 40Hz to 400Hz co...

Hello Jeffrey,BUILDING UPON the inherent/latent Lloyd Wright-esque and Frank Gehry-esque aesthetic potentiality of your midbass horn design, and visually integrating the total horn package as a system within these aesthetic schools (or derivatives th...

Of course i am referring only to the horn part of a 210-type enclosure. Below the horn cutoff, perhaps around 70hz for the 210, the remainder is filled in with a wooly bass-reflex peak, which gives these boxes their characteristic fluffy, indistinct,...

Jessie’s comments about my idea to position midbass straight horns from basement, upper- firing and his warning that the horn will get converted into a giant garbage can made me to think. I did not think about it but it is a reasonable concern. Hypo...

This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensi...
