[quote user="msaudio"] Romy I have not herd so much doulble talk in a long time. Some of the best sounding drivers on the market in the last 60 years, were for sound reinforcement. [/quote]
It is not my view. I wrote about it many times before...

there is one system that resembles what live music sounds like and its not a horn! :)To be honest I really have no idea of what topology these horns were setup like... all i have evaluated is there soundI like to go into something without any prejust...

I guess you cannot say you listened to a horn system if you dont have an upper bass horn.The upper bass horn has to fill in the response from the compression driver down. At this delicate range nothing will perfectly macth it but another front horn. ...

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, I think you are missing the accent of what I meant to say. The Class A or not is not important for compression drivers and the S3 in particularly. I mean it is important and it much be ONLY class A but I do not see any SS amps switching in cl...

BTW, to illustrate my point. Here is typical Goto inhalation. In fact this is the better among others as to be typical the MF divers need to be lined up horizontally. I can hardly believe a person needed to be more Moron to voluntary arrange drivers ...

Srajan La Pergola just announced that Danish company “FMJ Audio” began to make an acoustic phase tester. An acoustic phase tester is absolutely mandatory thing for anyone who uses horns. If a person use horns and has no ways to objectively recognize ...

Taming strange fullrange drivers is fun, doesn't cost an arm and a leg and there is always room for a second, third, etc. system. E.g. what to do with such a ridiculous unit? http://www.ciare.com/pdf/catalogo/HX135.PDFBack-loading? No problem when th...

[quote user="noviygera"]p.s from my experience of having a 500 sq. ft. listening room with 7 ft. ceiling and having two 18" woofers in a infinite baffle configuration, it is not enough to pressurize the room. I am talking about low and medium listeni...

[quote user="Jorge"]One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tr...

Of course I am not really talking about Rullit but only holding up his implimentations against his stated aims. This is certainly no special case, since most smart people learn the talk and the "look" long before they learn practicum, if they ever d...

Well, a lot of horns are put into box enclosures of course. This is really a complicated subject. The baffle must be dealt with in a manner similarly for all loudspeakers so designed of course. More interestingly is the potential fo...

[quote user="haralanov"]I think you wanted to say reflection surface, not radiation surface, right? Radiation surface is the surface that is directly attached to the vibration creating element (the voice coil). So the radiation surface of the horns u...

When many of your will experiment with building and listening your own horns and spend countless amount of time by sketching a configuration of your new horn assembly you then might come to an observation that Macondo Upperbass topology is very s...
|
|
Crossing the woofer so high is not really a fair comparison. The compression drivers needed to be in a bigger horn, and possibly be replaced with a driver that does 100Hz for certain. ...
|
|
[quote user="Romy the Cat"] I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let
say 120Hz from a compression driver would take too long horn and it would be no
way time-aligned it. So,...
|
|
Hi Paul. Looks like blendet paste? Thats not an engineering approach...I know from small closed woofers enclosures this construction kills a lot of K2. But it doesn't treat the k3 or higher. So you gotta be careful to keep the balance. But as horns s...

compression drivers are the way to go as far as i am concerned but obviously performance depends on the horn lens.my beef with ET-703 is that i don't understand its horn or whatever it is. if not an explanation i would like to see maybe some po...

I just spoke with a guy who have made both permanent magnets and electro magnets for loudspeakers.He said that the reason that electro magnetic speakers have a smoother and more grain free sound, is due to the temperature rise in the mechanical parts...

Hi all
The WE 555 is IMHO an interesting driver, made for a very spesific use,
which is driving a "full-range" horn in the theatre.
As we all know, the wide range system with Jensen 18"woofers and Bostwick tweeter came later, at first the 555 an...

[quote user="JLH"]Foolishness is too soft a word to describe the unspeakable garbage the Magico Ultimate is. They have mis-matched impedance drivers, improperly sized horns for the drivers, and made everything from metal. Then they go on an attempt t...

Angelo ,Romy is right .Forget about him and his advices. Go to the mountains and find your inner truth....:0)For years he's drooling that S2 although not perfect is the most interesting compression driver and now when there is the chance that this dr...

Again, I do not agree with all notion of Rubber sound that Haralanov seeded. I can not speak what was in the situation that “be” described and 400Hz crossover. I do have the 8” version of 25W driver (I think it is 21W) and my feeling that it sou...

After the painstaking setting up of the new Macondo, measuring all distance, paralleling the horns and time-aligning everything, after the setting up a correct level of the new channel’s attenuation (it turned out -2dB was necessary) I spent some tim...

A lot of people ask me about those drivers and I’ll try to compile my vision about them. I did try most of the possible tweeters: dome tweeters with cloth cones, varies type of hard metal domes, compression drivers with aluminum, titanium, phenolic a...

I have order 4cu feet sealed enclosure for two 15 drivers. It
is relatively small box but I need to hit minus 6-8 dB at 50Hz. The collection
of the drivers I have would be following: Vitavox AK51 and 15/40, Altec 416B
and 515B. I like Vitavox tone...
