The drivers are said to be 2@15", paper; 2@8", paper; 1@5", paper; 1@1", polyester. The X/Os are shown as 45Hz, 260Hz, and 2kHz. Does this mean that the 8" drivers are driven down to 45Hz; the 5" driver is driven down to 260Hz; the 1" polyester tweet...

The idea of two (or more) differing drivers covering the same range is intellectually very attractive with respect to tone, and maybe efficiency, as well. OTOH, the problem remains that very few drivers sound seriously good across the board over mo...

The best-sounding drivers I've heard will amplify a wide range of sounds from scratching or tapping differently at different points on the cone, or even from tapping or rubbing the driver frame. And never mind OB, some throw amazing tonal range and ...

So I am aasuming that you are referring the very low level capability of your driver or amps? The subtle nuances?What other drivers did you find did well beside the Vitavox. I always felt that most comperssion drivers are a little tightand need to...

[quote user="oxric"] And why did you not mention a Group Buy for ScanSpeak drivers earlier? I would have started one ages ago! [/quote] This is all because you are a primitive person with very simplistic and amateurish understanding of many things....

[quote user="jessie.dazzle"] Assuming one will not get anything under 50Hz (usable) from a 40Hz horn, I interpret the mission of lower-bass channels in the context of a horn system as follows….[/quote]
Hm, this is a bit tricky with bass. A pla...

Petar, I looked at the "custom" driver you posted the address for. It is interesting to look at, all right, but I am not set up to build drivers from scratch. Since I pretty much have to buy something that is either useable as-is or something that ...

[quote user="Romy the Cat"]...my light woofers would not be the optimum solution and I might need to use 18”-24” woofers.[/quote]Hello Romy!At least for corner horns I think I can say that lightweight drivers are the better solution. HBM's corner hor...

Hi all,In my experience it is VERY hard to get anything resembling realistic bass from a vented box, particularly with a Q of around 0.9 or 1. There is too much stored energy in the system and too much overhang. The best bass I have heard...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

I think this post need to have an epigrapher:

Preparing for my Midbass Channel projects

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

[quote user="guy sergeant"]I don't know to what extent they've tried to apply the Naturflux thinking to the Field Coil circuit. It would not surprise me if that was much more difficult to do. It may have made the costs far too high. I don't know. [/q...

Hello, Angelo

Yes, Avantgarde can do it if the situation is right. I ...

[quote user="Romy the Cat"]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.

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

[quote user="Jorge"] I have never found the law of diminishing returns to apply to audio! Going crazy always sounds better… [/quote]
Jorge, we need to have a perspective about those things. With exception of oxric’s episode, who still is not...

the difference, with standard stereo installations, where the bass
comes from down below and the highs come from up above.[/QUOTE]I suspect that much of this effect arises from the perceptual disjunction caused by using...

Back in end of 90s, we read articles by Thomas Dunker, Joe Roberts, Bruce Edgar, and many others (some of them were designers and some of them just publicists) who were trying to persuade that horns are some kind of advantageous topology and that...

OK, thanks. I would leave for others to decide what the “higher resolution image” might mean. It might be some kind of untranslatable Japanese folklore. The more vibrant color palette is definably a valid accomplishment, no one knows through if it is...

Oliver,
It might be anything including electricity. Generally compression drivers are very much vulnerable to the electricity problems, muck more than convectional drivers. Let pretend that distortions in powers lines are responsible for worsening o...

The Multifaceted Random Dipoles – what the hell is it?
Well, this is what Eugenie’s uses, perhaps without realizing it. I do not know how Eugenie came to it. I presume that he was buying over the years the drivers on eBay and now he decided in...

This is kind of shit that I hate. I went to AA and read a person said:

A few months back a guy from Europe showed up at this site proposing to sell a set Vitavox K15/40 and Vitavox S2 drivers. I did not need them, I have my own stash, not one looks like needed us as well. In a couple months he reinstated that the dr...
