So, I do not understand. You took everything out and use it as direct radiator or you still somehow load M4 into a horn? Are pictures how you use it available? Also, how you use it: crossover point and measurable range? I would be also interested to ...

I am on begining (1 week in progress) to design frame for my future horns. 115hz400hz ribbonand 200hz or direct radiator as fundamental channel.I like functionality of Jessie frame, and Romy "flying horns" look.I think my project will be ready at th...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

Say whatever you want but some of the vintage drivers has
it. Not all of them but some of them do and the question how to get it. I
always has been an enthusiast of midbass horn and I am very much the enthusiast
now but there are some topological ...

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

This is an article from Thomas Dunker's site (available in my Links Section) and presumably written by him. Although I slightly disagree with some of the statements he made about the horns “imaging” and some others but generally it is very good...

The first and the bigger thing that I like about them is that Anima is trying to use the vertical-horizontal configuration where the bell of the vertical horn serves as frame for horizontal channels. I love this idea and had a number of my own th...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

Yes, the tamed beast is an oxi-moron. I thought of my 808s as ragged, rough (grainy) and spitty, while the S2 was also ragged/uneven, but the roughness was more like the sound of a metal zipper. Anyway, I never heard either of these stock drivers m...

It took for me a few weeks
to put up a new direct radiator Midbass channels. Each channel has 2 of Vitavox
15/40 drivers is seals 2 cu foot enclosures. No filtration of any kind on
speaker level and Vitavoxes juts are driver from Milq LF channel t...

[quote user="haralanov"]Ironically or not, I have no practical problems with it, simply because I’m not using big UB horns. My upper bass channels are much more compact – 4 very massive 15” drivers with no horns. Their integration to my main widerang...

At Romy's suggestion I've created a new thread for this. I have been thinking about what sort of bass solution to use with the S2. I was hoping to be able to get the S2 low enough (c. 300Hz) to make this a bit easier, but it seem that onl...

[quote user="Gargoyle"]My guess is was referring to the pressure levels at the surface of the woofer(s) compared to that of a horn. The sound pressure of a direct radiator has to be much high to achieve a certain SPL at the same distance of a lower p...

[quote user="Horn Savant"] I then tested the two 416's in free air and they were 28 HZ each. Then I tested them in the horn - both drivers driven with signal and measured 23 HZ resonance. Better throat coupling - better than, say, a Shearer or Mirrop...

I'd like to point out that Fostex 500 MKII is very much not sharp and artificial sounding. If anything it's an opposite -little too syrupy , soft and round so it blends with cone mid better than beryllium tweeter. I have no first hand experience with...

In my opinion the trend towards AMTs in mainstream audio ist justified. They integrate very well with direct radiator midranges, even when they are crossed low. They are more dynamic and detailed than fabric domes, but not absolutely unforgiving. The...

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 ...

Thanks, El, an interesting driver indeed. It would be interesting to listen the thing though I have personally no use from that type of driver. Purely on the specs there are some moments that I would like to see different. The 250Hz resonance freque...

Not only ULF, and not only the usual "dead" audiophile drivers, and not just raw amp power. My experience suggests that direct radiator drivers from 10" diameter and under claimed "100 dB efficiency" (and - especially - in multiples) can benefit fro...

Well, I was thinking that there might be something of a "shock wave" created if they run too low, and the pillows might soften that up, almost as though one were trying to get the horn to behave more like a direct radiator at LF, where there is not e...

Skushino, Thanks for pointing it out. Unfortunately with all my desire to understand what CH Audio did turn to fiasco and I absolutely do not understand this LF section. Is it a duplex of 515 drivers with one loaded in this front shallow front horn a...

Well, the usual pivots are the tubes' basic current and voltage operating points. Like Romy has described many times, there is on the one hand an "optimal" convergence point at clipping. Then, there are the audible "polar" "qualities" that one gets...
