First off, let me say Hello to all fellow Audiophiles!
I'm an audio-obsessed 29 year old currently living in the United States (Minnesota), and have spent years perfecting HIFI systems in vehicles, and over...

Nope, I never heard about those
drivers. For sure a compression driver that goes down to 80Hz might be interesting.
A few concerns I would have however.
The people who make such a
driver would not come from nowhere but they rather would b...

Somebody "KCCT82" from Devil Audio site posted information about own installation.
Channels:
TAD ET-703 compression driver <12k-20k> (107db 8 ohms)TAD TD-4002 compression driver on 400hz tractrix <1.9k-12k> (110db 16 ohms)GOTO...

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]
I do not think I called you with names...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

Romy,
Funny stuff... especially the the AN piece. Equally surprised octopodes ? Brilliant !
As for the Bruce Edgar post ? Not as funny. And it's off base.
The Titan II system has a straight axis upper bass horn instead of a folded upper bas...

Guy, here some unconnected comments that you might find worth considering. They are in no order or importance, just random thoughts.

The KOSS Electrostatic unit was still installed , so I removed and checked resonance .The resonance was 136 HZ. I then tested it in horn assembly and the result was the same : 136...

Hello again, Romy.. let me see if I can clear some of this up....
first, you are indeed correct on your horn thoughts.. but some clarification is in order...

OK, this morning I tuned the playback and did some listing, trying to understand what was the problem. Sound was not just bad but it was very strange, it was almost as a mechanical replica of sound. I took my phase meter trying to set horns in ph...

[quote user="jessie.dazzle"]Is this because of the way you are driving them?When testing my one completed mid-bass horn (AK151 into 40Hz Exponential with 8" throat), and powering it from an amp that drives everything from upper bass to HF, the output...

Based on your claim that spray can foam takes time (days) to stabilize, it seems limiting the quantity used would be the right approach.To do that you need to fill the majority of space with something solid.The following might work for you:Get some 1...

I would like to expose what my intentions are what I was tiling above about Goto 555 or a similar 200Hz driver. My S2 does not stress the bottom of my 183Hz horn. My multi-cell is expositional and those types of horns do pick honk very aggressively ...

Throat is not that large. ~1/3 sd
Half space response is 50HZ. In room I would expect something lower.
Wouldn't comment because using a public forum for free advertisement is not my cup of tea.

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...

[quote user="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

Hi Be,the thread is about the "bad" reputation horns have with "audio" people. Applying liquid dynamics gives them more fuel for the fire, that is why I avoid using stuff that really doesn't apply. We have no real flow of air or "turbulence" in a hor...

In my first design, I kept them all in a vertical line. It had one channel less back then. When I added the 1" throat JMLC 1000, I decided, as the tweeter operates over 9.6k, the slight misalignment may not matter. Still, I kept vary and kept the fra...

[quote user="Romy the Cat"]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 ...

[quote user="TonyB"]Romy, what are horn flare frequencies of your horns? I understand that both are Tractrix. My guess is that the midbass is 125Hz with a sealed rear chamber and 4" throat. Correct? [/quote]They tunes for 115Hz and pushed in room dow...

This has been a very informative discussion folks. I am not a horn person... not through any lack of interest, but I am married. So, direct radiators rule.
However, I do not like the sound of speakers and so developed a process for turning cone and...

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

Hello, Ulf.
Interesting. The TAD1201H is 12-incher with resonant frequency of 50Hz. It has relatively low resonant frequency for 100Hz Tractrix midbass but you most like used 10” thought and consequentially shorter horn. The shorter horns beam...

"The top response of the upperbass channel is challenged. I do not know why it is – a wrong driver, a wrong curve in J-horn or wrong made filter… "
That sweep mirrors what I hear - specifically tepid and weak upper bass in the presence region betw...

Good morning Xandg, i thought the same and asked, so i got forced to knock and touch, very heavy & firm. As I wrote, the gravel-filled cavity at the mouth seems to make a difference. Anthony, thats the rooms yes :) It looks redicolous on the pi...

I believe that the Arum Cantus is typical of most ribbons in mirroring one of the principal failings of MC cartridges, a rising top end (over 20k), although I have not actually heard this - at all - with my own small Arum Cantus, and I just go n...
