[quote user="twogoodears"]Yes, maybe the 120 db/octave is THE trick for complex multi-ways systems of highest resolution, yet this barbaric:-) slope can ONLY be achieved by digital domain crossovering... unfortunately, as a satisfied user of TacT RCS...

Conditionally all imaginable loudspeakers in audio could be divided by two groups:
1) The loudspeakers where the pressure from the front of the loudspeaker isolated form the press from the back (Sealed enclosures, horns with sealed back chamber...

[quote user="Canuck"]Romy Have you ever tried a PUREPOWER device feeding something like the Torus RM20 which has a huge transformer and then out to the components? The Torus stores a lot of energy in those huge transformers. Do you feel this ...

Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...

Thanks behhl for sharing. I’m not well familiar with the LS3/5a’s Sound. I think I heard juts few of them but I can’t say anything about thier sonic performance. However, looking at the LS3/5a concept, purely intellectually, I would hardly find them ...

My amp is a stereo 2a3 / 45 .
Lately I find my self listening in mono because of the area of my apartment and because I can focus better on the reproduction .
So this is not a stereo / mono discussion , just better for my needs .
Im planning...

Running further away from Slav’s and Austrian’s “expressed sound” in music, walking across the Brucknerian soft monochromic fields I found myself lately to have very different interests in the sound that I am after. Well, I know how to make good soun...

Thanks, Paul.
I never saw this company. I did call today to the guy who run it and had longer conversation with him then I intended. Size and shape wise it was exactly what I was looking for. Unfortunately he does not do matching transformer b...

Ok, I partially got my sound. The top section of Remedies is
serially wasted and need to be redon. Still, was looking in my attic and I
found something that is make it so much better, at least in phycological domain.
I found a pair of Reds from 60...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

Actually I do not have the instability issue sorted out completely...I'm talking about circuit instability now, not the tube instability. Let us imagine all tubes are rock stable.As I see it there are at least two major sources of instability, in the...

I separated my two of my PP2000 in my rack with 3 feet space and run everything from one PP2000 and both Milq power amps from another PP2000. I also routed the incoming power cords that that are far from each other and far from outcoming power co...

Yamaha B-2 reportedly was a top-flying amp in end of 70s, during it very brief production period. It has in a way cult reputation, so I’ve bitten it.
I was forced to very mildly and temporary modify it, just running the signal directly the ent...

Romy,
Thanks for your comments.
When you write "...but the major question for me, if I were in your situation, what kind topology you will be using the lower bass channel and how you will be driving it."
I assume you are suggesting that the ...

Thanks, jtavan.
It was educational. I made some first steps already. I made a slow 233MHz (and presumable it would have lower noise with lower speed) machine with no fans, and a large passive radiator on SPU. Formatted it and loaded Win2K Pro St4. S...
