What is the argument USB vs SPDIF all about? Blowing smoke because the music is not in the center of the discussion, rather bogus technical hypothesis.I do not even read that garbage anymore because 1) they have no technical background that relates n...

How can a horn like this even get close to time aligned? Mount a tweeter 5 feet behind the mouth of this horn? I mean if it is only being built to play loud and without any advanced sonic requirements, then it is of limited interest here.I have never...

I can understand wanting to reach out to audio people everywhere, but think that this speaker is a joke for many of us here. It certainly has nothing to do with advanced audio or evolved music reproduction. Even on a DIY site, how much traction does ...

How do you even time align a Klipschhorn to any other driver? This is one of Romys axioms and I see no solution with folded horns. I am surprised that it was even mentioned!...
|

I think that most of us here consider horns to be decade devices. That means about 3.5 octaves can be optimally covered. 800-8000Hz in your case. Extending the "highs" another octave means a couple of things. If a horn is "too short" you do not get m...

Here is an excellent attic solution that will even allow for output to 1 Hz:

No problems with the suspension sag either!

On in my case is staying at operating temperature. All of my amps are tube......... My point is that if we can insert a UPS into the chain and improve sound, there is hope for the power supply! I don't really know of anyone using the batteries fr...

[quote user="Romy the Cat"]rowuk , you are not wrong feeling that what we do with
PS and Mains regenerator is kind of ridicules. Indeed we convert AC to DC, then
to AC against and then to DC again. If you use SS then it very much makes sense
to ru...

I have often thought that the necessity of a UPS comes from inadequate power supply design. Sure it is easy to buy a product to insert between the audio system and power line but at the end of the day, are we simply giving our power supplies an easie...

Audio is a AC event not DC. There is no wind blowing except for poorly designed ports. There is no reason to "optimize" for lowest "drag". The air molecules bump into one another and really do not travel any distance. There are claims of better sound...

I often wonder who REALLY needs real high end? Maybe this is the wrong description. If we look at custom made trumpets, violins, guitars for musicians, there are parameters that can be played with to reach a desired goal. The artisans results become ...

Maybe we in Europe benefit from 230V with half the amperage and not the grounding scheme? Seems to me that line noise would scale down by factor 2 when we get 15V from 230V instead of 110V when using "analog" transformers.

Thank you for sharing this. I have been experimenting with commercial switching supplies and various filtering schemes, but have not found a winning combination yet. I am very interested in trying this. Please make more info available....

Being a musician, I deal with constructive resonance every day. Tubes resonate as a function of length, boxes resonate as a function of the internal length, width, diagonals. Irregular shapes resonate as a function of volume, horns resonate as a func...

Thinking about that new supertweeter or tapped horn subwoofer. This picture could give you an idea if something else in the house may be affected........

For horns mounted on or near the floor, we have a phantom image below the floor plane. In theory, this means we could make that horn a half circle or similar, with a tremendous advantage in real estate. The theoretical advantages of reduced diffracti...

There is not enough mass there for a 200Hz ring. I don't know what you are hearing, but you need to go back to whoever built these things and tell them your stories.
If you really believe that the horn is ringing, add mass, ...

How did you determine that it is the horn. What makes you think that you can damp a horns mouth at 200 Hz. Have you never read what a room does to frequencies under 400 Hz? If not, check this site out: http://amroc.andymel.euMaxx, I think that you ar...

I am not sure if the questions are wrong. Maybe they are just too early. There are plenty of audio people that pass around opinions as fact. That is a problem and most DIY pride is not in the absolute quality of sound, rather that it works, has wide ...

Dear blue,I think that you are reading this site incorrectly.Romy has done an incredible job of documenting his personal audio travels. Consider this site to be a diary in that respect. It has absolutely nothing to do with DIY, except perhaps as moti...

If you look around the site, there isn't much DIY effort to just build "anything" here.You could probably get exactly what you are looking for by googling "Econowave" or SEOS though.On the other hand, you could just build what you drew and then tell ...
