Wow, Josh, that's a whole lot of writing! Truth be told, I did not read it all, but I see (and hear) the back-horn. Hard to believe after all your experience that there is still "more" out there, but maybe you will also find time to read extensively...

This new speakers from DeVore look interesting, though subwoofer could be better. I wish they were sealed box, but this is what it is. Unfortunately there is no chance for me to listen to them, but I'm willing to hear your idea or anyone who had chan...

KeaAudio. I think we are taking about different things. I was under impression that Goerlich speakers are really sandwiches – layers of aluminum foil inner-layered with plastic. Yes, I am not a big fan, in fact an opponent, of rubber shrouding for h...

I have never heard of any woofer that manages 50Hz lower cut off frequency in a horn arrangement. The simple fact is that a woofer does not emit sound under the resonance frequency (that is without artificially changing that, ie active). The resonanc...

Rakesh,Thank you for your kind remarks. I appreciate the close scrutiny you have given my previous post but I think you are at a stage of system design where many basics of your system should be considered and evaluated before the issues of my po...

Hey Romy I read your requirements of a mid bass horn. I am using jabo tratrix KH-55A(320hz) with altec 288 and I want the mid bass to go under that. I would use a trattix round midbass if it was possible. But it's just not with in my abilitys to buil...

I initially meant to put this post into my midbass thread (linked above) but then I decided that the subjects is self-important and it worth to separate in standalone thread. In fact this idea was formulated to months ago but I was holding to po...

WTF Roman , you trumpeted this as a very nice and sensible solution and now you suddenly don't like "LA Profile" ?....

Just new to this forum and there is so much to absorb.. One post I read suggested that horns be constructedwith dimensions to suit 1 oct. below the lowest Freq. to be used. I know that Mr. Le Cleache favours this ashe says the group delay is bette...

[We are faced with a situation of unwanted noise that is coming from a rock concert at the 100 meters away from our place which is about 200*200 meters area , the power of the noise at my place is about 90 db . the noise source is being broadcast e...

I had the same problem with my 6 foot, bass horns , which were built from 3/4 inch high density fiberboard. On doing some measurements back then, it turned out that they were vibrating for a few milliseconds after a pulse, giving a decent rise time b...

Well, this paper on front-loaded exponential horns is rather
interesting, I think. Since some Greek symbols and simple equations are
used, I allowed myself to present here my understanding of this paper in
the form of the following picture. Of ...

N-Set,That is a really interesting point for designs going forward; one step further would be to vary different materials for each layer. Microsoft Excel has an easy random number generator to automate the thickness calculations. Actually getting tru...

Considering the conclusions of my recent experiences that I described in the following thread:http://www.GoodSoundClub.com/TreeItem.aspx?PostID=6876I would like to share some of my observation that the people who would g...

I understand that "nothing changed in the horn dimensions if you go from between 10" and 12" driver". You are referring to the horn mouth I assume. Do you have a idea what compression ratio is good to have for upper base horn? It seems that 2:1 is ta...

[quote user="oxric"]If it were me and I had that basement that could be made use of, I would seek to achieve what you have done with your mid-bass horns in the loft. I know that you considered and dismissed the tapped horn idea some time ago but ...

Today a guy I know from south coming to my listening room to hear my payback. He is mingling with horns, he heard my installation in city and he is very much interested to hear my new listening room and the most important my new midbass horn. He actu...

Hi Romy…and fellow audio nutters. I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner. My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I h...

Is this type of driver not similar to those used in headphone?. Very high efficiency, wide bandwidth, very low XMAX. The lightest and fastest are probably the orthodynamic type like FOSTEX RP, HiFiMAN or Audeze LCD2....

Alright then synergy horns aside, what is inherently wrong with wideband horns? I can understand that there is bs implementations and explanations/marketing, but if we put to side CURRENT wideband driver limitations and only look at horn. If horn is ...
|
|
Well the thing about horns and wide band is that for them to go lower the horns needs to be longer, if the horn is longer the highs get lost inside it. The most famous and longer range horn is the WE 15A, but even that one doesnt do magic, some clai...

Oops sorry, I just re-read you post and you did said the “cub feet”. I read it as “sq feet”… so it came from it… If I have 12,000 square feet I would defiantly build a nice sleeping place for my Koshka inside a 50Hz midbass horn… That is one of the r...

I am not selling BR (honest), but if you - a horn guy - think about running a 150 Hz horn down to 150 Hz, perhaps that would put this into perspective.As one who has heard only "horn-sounding" horns, if I ever get to making some horns it will es...

Someone stopped me at the Alexis Park and told me: “Romy, there is a new Israeli guy in town with his amassing horn. He has a room at the St. Tropes and you should go”. I was almost offended! There was a new horn guy and I never insulted him?!!...
|
|
Yep, a nice horn design. I like hos they have a mid-range to
have the similar footprint/size and a lower channel. I guess a mid-range runs ~60
to 800K, wonder what driver they use in there. The upper range horn in a
typical “clitoris position”, le...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...
