[quote user="Romy the Cat"] The idea was very simple: to convert the C filter into RC filter, to employ the Silicon Carbide Schottky rectification diodes that showed themselves so nice in 6-ch Melquiades and to beef up the preamp with large bet...

After I spend so much time in experiments with ports, I found some interestind aspects in port loading. Our primary objective is to eliminate the nasty air resonances in port at middle frequencies, which kill all the lower midrange sound. It is achie...

Romy, Not sure I can add much more.... you'll find out yourself of course. Overall, I can not comment on the "enabl" treatment beyond what, Dave, Chris and Bud have said (Dave and Chris are the Planet10 guys). I think I would have tried th...

Pandora's Magic BoxRestoration of the music's dynamic range in historical recordings by: Pierre A. Paquin
We are now able to enjoy great recording of the distant past, thanks to the efforts of several successful and dedicated engineers who have had...

.... of “the buffer transparent” and it does not look as transparent at all. The buffer adds some very minor dynamic compression, very-very minor transient’s corruption, some overlaying sense of grayness and generally if has more fatter sound th...

[quote user="morricab"]Well Romy, IMO they are not just tonally different they are more tonally correct, ie. they simply have less coloration than other technologies. Just listen to a recording sometime made with a ribbon microphone and you wil...

Romy dropped by yesterday. He goddamn demonstrated how "yellow" and compressed the Lowther (Reps-1, in my case) is, using my system, by simply playing other channels and the Lowther channal separately (mine is a 4way multi-amp set up, so it's v...

[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...

I have order 4cu feet sealed enclosure for two 15 drivers. It
is relatively small box but I need to hit minus 6-8 dB at 50Hz. The collection
of the drivers I have would be following: Vitavox AK51 and 15/40, Altec 416B
and 515B. I like Vitavox tone...

Again, I do not agree with all notion of Rubber sound that Haralanov seeded. I can not speak what was in the situation that “be” described and 400Hz crossover. I do have the 8” version of 25W driver (I think it is 21W) and my feeling that it sou...

1) No, the cabinet is not 10K more. It's 19.5K more... and not even Baltic Birch, but Douglas Fir. Again, with a long justification about the special laquer finish used how expensive it is, how long it takes to apply, etc....

[quote user="tuga"] Romy,On the subject of speaker design, I don't think you'll disagree if I say that your "quest for a better monitor" was unsuccessful.You mentionaed at the time that the speakers should respect the following:1) Perform correct in ...

One of the main advantages of Macondo configuration was the fact of multi amplification. As with any other systems which have a dedicated amplifier of the same type to each individual driver Macondo can run over dynamic range with amazing ease th...

I can relate to your point about mating SETs with inefficient speakers. I guess since they don't sound overtly bad when they clip, some people feel they can be run with less dynamic headroom than SS amps require. The resulting compression probably ...

Hi Romy, Hi Jeffrey Steve and I have been working on the bass compression driver for quite some time now, about 3 weeks ago we made some design changes that really paid off, as of now I'm convinced that a compression driver is...

It seems ironic that the path to bringing the single-channel DSET/narrow band horn idea to market would invlove traditional marketing per se as much as the melding of evolved listening with cutting edge technology. While there is rote work...

I was right before but now I really review my rightness for a new perspective. Yes, the compressions drivers are the subject of clean signal but it what I witness with the new 6-chenals DSET put what I said above in another extreme dimension. I do no...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

[quote user="msaudio"]If you look at the picture second from the the top, you will see 2 woofers mounted in front on the baffle, notice a 2 piece horn from the baffle. Klangfilm never had such a horn, they would start at the baffle and curve out. The...

[quote user="steverino"]Well of course they are Not reproducing a drum at twice live volume they are merely playing a recording of a drum at higher volume. If you analyzed the wave form it would Not be the same, just louder. It would be distorted. Th...

I came across an article:http://www.ultrahighendreview.com/enigmacoustics-sopranino-super-tweeter-review that introduced electrostatic tweeter that might be interesting. The company has a web site that is to unpleasant to reread/navigate: http://www....

The initials post was the body of email that Kostas sent to me and considering it’s format he presumed that I will me post it on my site. So, I did it (with his permission). I ran all those tracks once (some of them just a few seconds) and below is v...

I got the new BSO 88/24 files them briefly listened a few fragments. Generally I do like them and they are nothing like the 320kbps multi-channel WMA that BSO marketed before. My fear that the files might have issues with tone turned out to be not ne...

I could forgive Mr Rose his personality defects if he was producing soundfiles of some distinction rather than just doing 24/192 needledrops. The scary thing is that his patrons contend that these concoctions are the equal of using the mastertape. As...

Yeah, that is low life for sure but that kind of takedown is becoming more common. People are copying the politicos (of all types and persuasions). If they can't give a memorized answer or it jars one of their buzz phrases they feel free to slime yo...

We are so overly familiar with the music of the Romantic era (and to a lesser extent with some 20th century orchestral music) that we tend to overestimate the importance of dynamics overall in music and in listening. Obviously, abrupt and frequent dy...

Here is where I stay with my enigmatic Remedios project. I build inside of top box at resonator that I tuned 50-60 hertz. So basically it is under two square foot enclosure with a port tune at the bottom of resonance frequency. The port is shooting ...

Oh, yes this is the whole idea of Remedies, it is not only a Red combination but it is an assembly with midbass channel which would make it a conventional box loudspeaker. You see, with all interesting things about Tannoy Red the woofer part of t...

One funny thing about "dynamic range" is that different audio camps claim to desire and get some form of "improved" "dynamics" from their respective, widely differing topologies, from panels to single drivers, to plasma, etc.Maybe they don't claim to...

[quote user="de charlus"]It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound...
