[quote user="Paul S"] … When I listen before I switch to battery, then listen after I switch, the unit starts sounding better and better over about 5 minutes, then it improves very slowly like it does on wall polwer, depending on how long I've warmed...

Hi Anthony. No miracles. Round shapes happen to be far more rigid than flat. That will also increase the pressure on the flat opposite plate, which has to be of quadruple stability. You can easily eliminate this by the so called impulse compensation ...

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...

[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...

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...

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 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...

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...

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...

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...

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...

Adrian, is the room raised floor or a slab? If the former, then wall-mount makes sense, especially for a TT. If slab, then you have more options, as far as spreading things around. Soft carpet or hard flooring factors, too. Yo...

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...

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 ...

[quote user="Romy the Cat"] The sound during bad electricity days is all about noise, all imaginable noise; it is like fog, dull everything into some kind of universal grayness. The colors are dirty, the upper mid and HF are literary dirty, the HF ar...

Romy, you might want to re-think 2 guys and pneumatic casters under a bare frame dolly for a 950 lb. unit. If you insist on doing it this way, I hope you will make and post a video of the event. I'd at least consider solid, rated casters, espec...

[quote user="Romy the Cat"]I made the 543rd remodeling on the Opera room and move the video playback equipment to the new, I hope the last location. As I connected everything into PP2000 as it use to be (not PP2000+) but older not “Plus” version than...

Regardless of where you get them made, I would opt for free-standing horns mounted on wheels, as this allows the most flexibility in integrating them with your as-yet-unknown space (for example, you could build such horns into a wall, mount them in t...

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...

[quote user="Romy the Cat"]The only thing that I do not have is some kind of stand alone, mid room HF eater that I would like to place between speakers and the back wall’s windows, something like tube traps or the similar. I do not like the tube trap...

i will upload a pic.i have no problem with an additional channel!1.)i dont have to build it right now, the 60hz-horn with the s2 mf and 2405 hf will sound quite nice(at least i hope so;-) and i have something to build on.2.)i prefer to do things by m...

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...

[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 ...

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...

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...
