Dear Roman and all... also unrequested/unsolicited, MUST give my opinion on the above... I had to translate my 2,3 meters from my Gotorama speakers system, and obtained 7,6 or so feet... it's angled 110° in front of my head, placed on 5,3 meters long...

The horn mouth will be 3-4 foot from the wall but you are right the MF/HF will be closer if i dont delay them so i can bring them out from the wall. If i line them up purely acousticly then they will move forward at least two more feet which puts the...

Hard to say for sure where all the trouble reported with regenerators comes from, but I absolutely agree that the opportunity is still there to make a simple and straight-forward success of a model (not just one example...) that actually consistently...

It is a lot of work but it a lot of pleasure to work on it. I put Macondo in as is position. The ceiling will be painted and painter will be moving the speakers, so where the speakers are now is irrelevant. Still, the image below gives an idea what w...

What a great rap! At first it triggered my gag reflex, but it did not take long for my eyes to roll back in my head while I began to run the numbers: how many cords, which models, etc.OK, it filters out certain orders of noise. So how does it do wi...

[quote user="xandcg"]Many thanks!How do I calculate horn mouth, cycles and length?[/quote]The required full-mouth radius of a circular horn is given when the circumference of the mouth equals the full wavelength of the frequency in question. So give...

Hello Romy and others,Ive been away for a long time taking care of my health but i'm back with renewed interest. I am moving to a new house in the future and have plans for a dedicated music room (and an occasional movie) The space is however much sm...

I recognized that I have tired for the last week like hell. Do not ask me what I got tired from – I will not be able to say. That whole moving, packing, unpacking this was too exhausting… The good thing is that I go an interesting room as a resul...

The problems with Smart Grids
by B. Blake Levitt and Chellis Glendinning
How is it that so many intelligent, inside-the-beltway environmentalists are buying into an eco-health-safety-finance debacle with the potential to increase...

I need to admit that I absolutely adore my listing room. I like absolutely everything about it and if I enumerate what hat I like about it then the list will be long. Ironically, from a perspective of self-education I sometime try to nail down wh...

There were had few days. First it was complete distraction of my listening room, than the contractors put the new hardwood floor together and then the complete rebuilding of the listening room, back to the sate it was before. Well sort of…

Robert, Yes, of cause I understand it. The problem is that when I laid down the pipes under the midbass horns there was no larger diameter available then 6” pipes, there was no more clearance under the mouth. So, my listening room has two 6” pipes an...

Josh, Hope you have time enjoying your horns and new production Fane 8ms when not busy getting our world into more financial woe! Your query reminds me that it has been a long time I have not updated this thread and I am posting some of the lates...

Something very interesting happened today in my battle with the incessant buzz in the PP2000. No, it did not go away unfortunately, but I learned something new.Perhaps inspired by the recent discussions around the original pressings, I decided to spi...

In my case, I have not observed any fluctuations in sound quality other than those resulting from my own state of fatigue (maybe they are doing something right with power generation/distribution over here... I don't see many complaints coming from ou...

It was an interesting event today. I have a big air compressor home that got broken, so I borrowed a portable electric compressor from my neighbor. I plug it in outside the house and blew up the irrigation system, preparing it for winter. Then I bro...

Romy, is there any way you can re-arrange tor re-configure the speakers in order to accommodate the stacked 15" drivers, or are you determined to push your speakers against the wall where they are now? I ask because I have heard stacked 15" drivers ...

[quote user="jessie.dazzle"]Assuming situation 2 is possible, receiving mid-bass primarily as reflected sound, one would have to take into account the reflected path of that sound, and how it describes the mid-bass part of the image, relative to the ...

Doesnt sound like a problem where you have to make any drastic changes. Using horns for some time, what is apparent in my system is that it requires quite precise placement especially if you are demanding and have experienced things that few people ...

The brickish finish does not make me cringe, in fact I do like the idea. I do not feel that it would be some kind of non-truths. There is no truths or non-truths in it. The only a few first feet of the horn will be visible and then it will go to dark...

I would have to say that loosing Gabo is a far bigger tragedy than damaging any sort of reputation I might have.About making horns I don’t yet see this obsession as a full time career, and if you ask I just as well would not be able to answer what dr...

Here are a couple of shots of how the inner surface of the new rectangular mid-bass horn will look (shown with driver; an AK151). This model is based on a calculation for an exponential horn.These images do not show wall...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...

[quote user="Romy the Cat"]He use Magico monitors and with 91dB sensitivity and 4R impedance I would be very surprised it I see any SETs in there. It even more interesting that his Magico speakers are sitting right next to the wall. I do know how Mag...

N-set, you may remember that from the beginning I encouraged you to try a wall mount, for all the reasons you have just cited, and this approach seems even more obvious if the walls are concrete/masonry vs. floor joists and sheet subflooring, not to ...

Collin,I am pleased that you found my suggestions worthwhile.
I approached the issue of your music room with two questions in mind:1- How to avoid the structural angle from interfering with the sound2- Would an enlarged room be worthwhile...

I dont think a standart klipschorn would satisfy the cat. I had one, then I heavily modified it and in the end I built my full scale horn system. I still keep that modded khorn system as a second system.If I may suggest, if you use klipschorn, you ca...

Thanks for all the comments. Seems like everyone is pretty much agreed that curves improve things but large radius curves are better than small. We have made curved panels with a radius from 4 inches to 35 feet. I attached a pic of one of our more...
