[quote user="Chirag"] Still, I do miss the dynamic lower MF of the 15" woofer...[/quote] Well, this is it. I really do not know what it is and I (and you) call it “dynamics” but it might be something else that juts appears like dynamics… I did not pl...

I have been searching for a good discussion on this subject for a while an yet to come across anything that really explained this: What are the causes/factors of compressed sound? I know it when I hear it, and have heard this phenomenon attributed to...

Petar, wonderful observation as usual. I would like to add one factor that is always there but practically impossible to consider predictably. Any driver has suspension (with exception of suspension-less drivers that are not suitable for bass) and th...

[quote user="Romy the Cat"]I wonder: does it mean that you will take the rest 28 drivers? Hm, are you trying to research the subject of the drivers’ critical mass or become a speaker maker? Be careful with their claims that they will be “manufactured...

Mark,
It is hard to say. I owned T90A sometimes in 2001-2002. At that time I was going through the drivers like crazy and T90A was just one of them. Looking from now I do not think that I gave to many drivers a chance as I did not “work” them trying...

[quote user="Merlin"] ... I often note that you describe TAD compression drivers as being not to your taste. Could you tell us which of their range of drive units you have direct experience of and on what horns? [/quote]
When I experimented wi...

Actually Goto does not have default 5-6-7 way systems. I have seen that they recommend 4 ways systems. Definably in the fields the dealer and distributor load their ignorant customers with as much drivers as possible selling them 55 ways systems.&nbs...

[quote user="Saturntube"] Anyone has some sort of comparison between compression drivers against cone (dynamic) drivers in a this huge mid bass horns, or even upper bass horns. All I heard are this guys from Germany with the out of reach expe...

[quote user="el`Ol"]Romy,
I find the Veravox 5 drivers are strong contenders when searching for elevated sensitivity 5" drivers. I heard the Veravox 5X in combination with Shindo SET electronics and found it very natural-sounding. Both 5ers have cer...

[quote user="angeloitacare"] Of course, Avantgarde with their price tag never will be for mass consumption. I offered Holger then to see If I could commercialize his horns in japan, Do u know how much was the dealer price for a pair of trios at that ...

I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you. Let pretend that I went for exponential midbass profi...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...
|
|
Hm, Yes, I kind of forgot the idea of multiple compression drivers blowing into the same throat. I never was too warm to it but I do admit that it would minimize the length of the horn. For sure the right solution would be to make compression driver ...

I do not like the AMT Heil drivers at all. I have no idea what 5 times higher transient response they claimed but to my ears all AMT drivers I heard sounded like their upper notes are covered with 2 inch deep saliva. The Heil drivers are in my view t...

Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

[quote user="el`Ol"]I think they could could make the sound more pleasant with an overkill of second harmonic distortion. But for people who prefer that kind of sound a relax-horn like Anima would be better anyway. No real solution. Maybe they should...

I wonder if anyone recognizes the drivers of the Cessaro Horn Acoustics? I thought that I know all of them but looking at Cessaro’s compression driver I have no idea what it is and I feel that my ego severally hurts. The pictures on the Cessaro site ...

I have recently been thinking about efficiency. Apart from enabling you to use low power amps, is there really any reason why high efficiency is better than low or medium efficiency, all else being equal (and I know perfectly well it never is, but le...

Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that drives them. With that kind ...

[quote user="jweiss"] It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) [/quote]
