... or wondering if it has any new insight into horn design.I did not read the book but I find funny that person who presumably do not “believe” in horn write a review about the presumably horn related book. It would be similar to ask a blind person ...

Let's see "series crossovers"... hmmm, very interesting. Something to look into? Where can I get more information? Should I contact an audio tech to design one? Can I send the current crossovers somewhere for evaluation or do I also have send the...

I just found this thread and can comment on the Enabled DX4s. Limono (Wojtek) very gratiously loaned his Enabled 8 ohm Lowther DX4 drivers to me this past summer (summer of 2008). It took my a while to make the crossover for these (I have...

I was slowly looking for a compression driver that would go in my Fundamental Chanel down to 200Hz. The YL Acoustic 550N attracted my attention. Then I realized that it is the narrow throat type of the drivers, aka WE555, not exactly that I would...

I prefer to use closed-cell polyurethane for my horns. It is light, strong, dimensionally stable and acoustically dead.It was used very successfully by Electro - Voice on their SM120a radial horn.This horn was designed by D. B. Keele and was used in ...

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...

I heard a friend's horn system recently and was very impressed. I don't have the resources to put together a diy system as discussed here, amazing as they seem, but am looking for recommendations for commercially available finished horn speakers that...

[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...

Got the ultra low DCR toroids coil and pit them in use. Yes, it was very right move and they a bit trimmed the midbass tail. Playing with inductance and listening how the midbass decays (measurements are worthless in this case) I ended up with 4.8mH ...

Romy,I understand your situation as a result of the move. It is a good thing because a system that is out of proportion with not work in a family environment and ultimately you will be battling yourself between sound and family priorities and practic...

I had a number of discussions about ribbons loading into horns and I generally do not welcome this idea. There are a few reasons why it never work properly and one of the most convincing is that in order to develop enough output from a ribbon you nee...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

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. I do believe, in a 2 way speaker system crossed over at 800hz with a good wood horn i wil...

[quote user="George"] I am not quite understanding part of what you say:
"It is very difficult to make a generalization about it but generally this quite “large bloomy space” will be a space equal to, I would say, 1/8-1/12 of the room ...

Hi i am a new forum member and recently i built some speakers using Altec model 19 components 416-8b & 802 G. I built some 7.5 cu ft cabinets with two 4" diameter 5" deep ports this is the optimum cabinet size for the 416 i ditched the 811 horns ...

Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

[quote user="cdwitmer"]Dear Robert and Roman,[quote user="Romy the Cat"]
To spending $40K for let it be even good single-driver loudspeaker is a summing of absurdity in my view.The Cat[/quote]For some people that is almost certainly true. But to tu...

I don't know why the Berning topic gets everyone so worked up. No need for another ZOTL screaming contest. Is this not a hobby where we explore many solutions? It is a difficult subject technically. I for sure can not speak about th...

[quote user="twogoodears"]Hi Keith and congratulations for your new babies... I'm truly jealous of your room size.
Me too, as I previously wrote, assembled a VERY similar rig, vastly inferior to you welded supports, any, using the same approach: S-1...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

Hi Samuel, I see that quite a few replies without much in the way of suggestions. Romy will not give you what you want, ie. a shopping list of speakers to audition, but I will give you one or two recommendations that I think sound quite good in...

Hi Romy, hi folksMy intro hello and first post, i just had to sign up. Just found the platform through googlin some hornstuff and came back too often.Especially the resonating oops was the latest topic that really cought my attention as im familar, a...

At this point I think that the main advantage of efficient speakers is that they represent the best chance for a sort linearity that to my knowledge can't be gotten any other way. It seems like inefficient drivers simply do not sound the s...

I am surprised with all your reaction to my comments as it looks to me that you do not get what I am saying. There is absolutely no need to listed if the sound changes or not. The “sound changes” is not the fact that is under discussions and of cause...

I think I remember James saying that the center channel should be the strongest channel, and if this is the case he might not scrub the full 6 dB from the L+R "sum". James did say the device "corrects" for mistakes embedded in the original, wrongly-c...

Finally, it has happened. Sound. Two weeks ago I had a couple of mates help me carry up and install the first DSET on its pedestal on the horn stack. It was quite a bit of effort and three were definitely required for the heavy but delicate operat...

[quote user="N-set"]Anthony, I'm sure you realize that air springs and bearings can only isolate from the structure born vibrations. Placing the tubes so close to the speakers you give them a great chance to catch strong airborne vibrations. Or will ...

For the past few months, I’ve been looking for a solution to a problem – how to recreate through speakers the same sound that I get through headphones. Why did I embark on this quest? Well although I’m quite happy with my headphones, I miss being...
