[quote user="Jeffrey Jackson"] Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns... [/quote]
It is why I use cone drivers f...

The Other End of the Single End: Modern Horns Done With Flare An Interview With Dr. Bruce Edgarby Dave Glackin, printed in POSITIVE FEEDBACK. 1996
Dave Glackin interviewed Dr. Bruce Edgar in his home, prior to the 1996 WCES. A follow-up on the speak...

The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

Not to dismiss the matter of the (non) existence of the FC L405, since I have not seen one, and I do not know (or care) about this...Regarding the "applications" for the cinema/PA-type drivers, broadly speaking, these drivers were/are "purpose built"...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

I like those ideas for tuning texture, and would add the way the surround is done and how it is clamped/bedded, which might be relatively easy to control, maybe even on the fly (with some sort of cam, for example). So far, it seems to work best to "...

|
Gordan, you may be aware that I have blabbed quite a bit about the Lowthers at this site. The problems with getting the best from the Lowther are not really that different from optimizing other drivers via networks and other range-limiting strategie...

Jorge,I would hope that the specifications of the Fane 8M drivers would not depart from the specifications of the old 8Ms that you have helpfully attached here. I just sent the pdf file to your email directly, not having seen that you had posted it h...

John, I have to confess that I feel very not easy about the idea of Synergy horn. I did not hear the Danley Synergy horns and I have very superficial understanding of what he is trying to do with the whole Synergy/Unity idea. The whole idea does ...

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. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

The big RCA field coil is the best thing about the Cogent system. It has great "promise", based on what I heard. Although their methods of "developing" this driver seemed confused to me, they do have truly encyclopedic knowledge...
|
|
Jessie, your post catches me thinking about multi-channel driver matching, as well. I am not familiar with the Fanes, but I wonder if simply throwing more power at them would make them nothing more than louder, so they would then "match" the res...

As late as the 1960s every self-respecting hi-fi nut had a "secret recipe" for "speaker dope". My own guru would not give me his exact recipe for speaker dope but insisted that developing the stuff was a rite of passage I had to go th...

Well, Yoshi, at least you're on your way to getting your speakers more of a piece.I have for some time warned people against a mix-n-match approach with the DEBZs, based on my early experiments with them, and it is true enough to say, I think, that&n...

Surely one of the objectives of this site is to allow people to be guided towards good sound by discussing the issues involved in getting there. Whether that entails discussing the merits of different recordings or performances or whether it entails ...

Cessaro once again didn't manage to find electronics that compensate the cold TAD sound, so the Silbaton WE demonstration one or two rooms away was quite a contrast. Without being addicted to that kind of sound and without having too much listening e...

ZZ, clearly, no single driver or pair of drivers can reproduce the range and power of an orchestra, and each of us deals with this according to our own personal demands and resources. The concern of this thread is trying to juggle/work with "phase" ...
|
|
Romy, I am not clear from re-reading how low you plan to go with a 4" to 5 " dynamic driver, like you mentioned a few posts back. I thought I read that you planned to go as low as 70 Hz with this channel, which confused me when ...

1: If it is not patently obvious to W that Romy is far from enamored with what I hypothetically propose, then it would seem that W is grievously wanting in terms of intellect, a more troublesome failing in the world at large than errant taste in loud...

Yes, Robin, while the whizzer can do higher frequencies, it comes at the cost of ragged response in the mid-range for the typical "full range" driver, and it also simply adds mass that precludes better HF performance that might have been gotten with ...

symbiotic diaphragms were never used in the 19's. this may be part of the "bad sound" that this guy was experiencing.they used the 802-8g driver with ultra light epoxy and aluminum diaphragm that allowed hf response up to 22,000 cycles when pairedwi...

I suppose I have "learned a lot about drivers" and speakers over the years, but age has overtaken my production capabilities, and I am selling my stash of drivers. Included for sale is the Holy Grail of lower mid-range drivers, a particular variant o...

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 ...

hi romymy goal is to design a hornspeaker with drivers, that are today commercially available, s2's are not.tomorrow i get my bms horns from bd-design, then i can say something abought them. as they are coax, with tweeters, i did not design a t...

... my only experience with newer, expensive Berillium diaphragm Goto drivers, has been a mix between "Wow, I'm listening to a +35K euros speakers system" and... "Gosh, music do not sound this way"... this of course was due to some crossovers tuning ...

Not to "defend" di-pole, but just to clarify, the "Rule" is: Thou Shalt Listen to Thy Results and Be Guided Thereby. Just like "horns" or following Horn Resp won't get you a good sounding horn system.For most, it is probably best to stick to the top...

[quote user="Rewind"] The drivers we use may be superior or inferior. As long as mine are the best I could possibly afford I can relax. I do love horns, and I can probably find quite a few errors in my signal path. If they are there the horns will am...

I have about 50 old "special" drivers, and I have wrecked quite a few trying to make them "better". It's slow and imprecise going without manufacturing capabilities. I have successfully replaced surrounds and spyder using "factory" or "factory replic...

Well, Tannoy tuned all their 10" monitors to play reasonably well down to about 50 Hz. Their monitors I heard were all variations of ported, with some of their "newer" monitors (70's?) using the ports to create more apparent bass, and those monitors ...
