Hmmm... Thorny, difficult topic...The "integration" of HF certainly involves its "disappearance" - as "HF", as such - "into the soundfield". At the very least, Tone ultimately depends on this. But there also appear to be other benefits from "ge...

[quote user="Romy the Cat"]Indeed, I did not realized that I shifted my thinking in this thread and an in my general views from the ways of using those “Resonating Oops” to the subject of Injection principles. I think I did it because Injection, as I...

Besides the single driver Aporia (which I haven't heard) I don't think Silbatone has made any speakers. So they don't 'employ' GIP drivers. I think GIP is a separate Japanese company who have just been invited to participate at these German show...

Thanks Gregm. It is interesting that I completely forgot the TAD PT-R9. I was looking at it 5-6 years back and spoke with AudioKinesis ‘Duke, who reportedly knows them well. My reservations that time were the very same as now: with 97.5 dB/W sensitiv...

Your rules say no direct answers so forgive me this one.
My horn is a true 21Hz horn.If you want to do the calcs:(More or less) Throat 6264 square cm.Mouth 48312 cmsq.M or Q 0.7 depth 3m.Quarter space loading.It does not quite make 21Hz.-3...

First of all it was quite interesting and quite educational. Second of all it answers no questions but rather creates more questions. Here is what I try to compile some my observations and thoughts on the subject.
I have a local guy who red my site ...

If one dht is good, two must be better?
I don't know. Some people like combining 6C45 etc with DHT, supposedly mixing the appealing qualities of each. Other people find that using a 6C45 (or other high-gm tube) with a 300B just makes a 300B sound...

Romy, Now you mention the issues here, I am thinking about what the differences in quality might be due to. I notice that you haven't explicitly said which is better, super or regular... so think of this just as brainstorming as to why things are... ...

[quote user="el`Ol"]A $$$ solution for a bass array that comes into my mind are the sandwich cone drivers from Accuton.Monstrous neodymium magnet, underhung voice coil (for low flux modulation).Very low Fs.Relatively low QMS for use in sealed enclosu...

Looking at Paul keep barking at the APS "success" I become to think what would constitute success in electricity battle. From one side the sonic result that PP2000 demonstrates is an indication that he battle is over. Is it? Sure the PP2000 as a devi...

Well, spent a few more hours to listening Avicenna. Although it has much better sound then from the wall but there are a lot of moments in this sound that I do not like. It is kind of freakish and demoralizing as Avicenna feeds system with absolutely...

to be clear:
i do have some expectation that 'my final solution' will consist of dedicated amplification per driver in a substantially horn loaded arrangement. I have some expectation that amplification will be single ended and quite likely have a b...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

[quote user="op.9"]I now run my 'tweeter' amp 1st order high pass at 2200hz (driving BMS 4540nd in 1500hz leCleach horn) so my impressions might have some bearing on Romy's new amps. I was playing around with operating points and components in my sin...

[quote user="cv"]Romy,Are you currently implementing "nominal" 3200Hz x/o on the mid range channel S2 using a cap at the driver? I know this works nicely to ameliorate the "secondary" resonance of the plastic edged diaphragm.Reason I ask is because t...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

One of the problems with horns is the inflexibility of frequency cut-off: you are limited to a discrete number equal to the number of horns you have. This makes experimentation difficult without having an absurdly large array of different hor...

Probably not one subject among horn enthusiasts does not arouse as much fantasies as midbass horns. This subject in one way or another was discussed at my site (look for the linked threads) but I would light look at the subject of the Midbass ho...

[quote user="haralanov"] My driver has not even a single trace of tizzing top end. Tizzines is intrinsic feature of ribbon drivers (including RAAL), not of well designed paper drivers. Actually, the heart of my acoustic system is ultra high perf...

Fostex T 500A MK 2 Horn Super TweeterArticle By Bill Gaw at www.enjoythemusic.com

Joe, I do appreciate that that invitation is open-ended and I might take advantage of it sometimes. Frankly I do not feel any specific temptations that I need to “drop everything” and to run to another side of the globe to audition the Silbatone. The...

Teodor, there is nothing to ask excuses for. You do what you do and it shell be absolutely irrelevant to you what others think. There are no forbidden topics in this forum. It is not about being forbidden or following some kind multi-channel religion...

[quote user="haralanov"] Some time ago I also thought my upper bass channel is flawlessly integrated, but when I added another, symmetrically arranged UB driver (over my WR driver), I quickly understood the new configuration is MUCH more expressive a...

[quote user="haralanov"]Actually I see the biggest benefit (besides the huge sound body) in the fact that such a configuration allows very precise adjustment of the way how the harmonics of each UB channels touch the midrange, by simply dealing with...

49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low res of your design, of...

In one idealistic configuration I envisaged for myself, for a situation where cost and practicality no object, the basic room shape was pentagonal, with the facets ot the pentagon curved inwards to eliminate parallel reflecting surfaces and simultane...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

Haralanov, good post, clearly indicative to a person who uses single-driver speakers. :-) I would have a LOT to say about it. The subject was very deeply researched by me in 2001-2002, before I had my site. From my current standing I disagree with yo...
