It is only available here for purchase from ORF. Blomstedt's artist agency has no access to the recording.http://oe1.orf.at/kontakt/mitschnitte...

There was some noise from them about releasing a CD of the tour. I am not sure how seriously the Bavarian Radio treated the recordings however.My daughter works at the artist agency representing Blomstedt. I will ask her. He personally likes the Gewa...

Herbert Blomstedt had a tour this past summer with the Bamberg Sinfoniker. I didn't get to hear them in the Stift Church in St. Florian, but in Würzburg in the Dom which also has a very nice "bloom". The only disadvantage was that the horns were sitt...

The order does not matter if you have an accessible database. You can just randomly give them a catalog number and sort in the computer. It could also mean that you discover treasures that normally are not even on the radar. The degree of database ma...

You have to consider the latency in DSP ULF solutions (regardless of filter settings). It is considerable and if the rest of the system is phase aligned, there may be some problems in location of the ULF drivers.

Romy, you have documented elsewhere here that a port can be useful IF you crossover above the port frequency. I have had similar experiences with well damped, high passed transmission lines. Some woofers like room to breath!...

Do proper horns "suffer" from K2? Do you not think that the back chamber loading is part of the engineered concept? Are you sure that reflections from the room that travel through the horn to the diaphragm would not cause more trouble? How can yo...

It seems that brainlessness knows no limits. Both Mr. Hansen and Mr. Rankin speak nonsense. Wasting time on text like this is like reading the brochures from extreme audio equipment. All the things that "audiophiles" expect someone to say, get sa...

Remember wirewrap with the sharp cornered posts? The amplifiers that I built that way are still noise free after 40 years. 20 turns or so per post work just fine and those connections can be shellacked....

I read an interesting post by Martin King, the MathCAD wizard that created some sheets to predict driver behaviour in different types of boxes. He had 3 groups of speaker enclosures: boxes so small that standing wave resonances (sealed and vented) ar...

Some drives do not get along with certain reflective surfaces. I had a Philips that played just about everything. Then I bought a Yamaha and all of the "gold" colored CDs would not play. I think that your dirt issue is not the real problem. If th...

Amir,you have now posted twice that "proper" USB is better than SPDIF. The problem is that it isn't, unless someone makes up rules to define their own sense of better. The problem here is that they have not defined anything that is better. Both metho...

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.
