Since the greatest differences in audio are among listeners, there is no need to argue whether such things are audible.However: While it no stretch to say from personal experience that such things are audible, it is very much a stretch to s...

I was sitting in my fireplace room; eating my freshly cooked oyster mushrooms and listening a master dub of Munch and BSO take on Damnation De Faust. No matter how primitive the setup was in this room the experience was enjoyable even sound was annoy...

[quote user="oxric"] You have often questioned the nature of my relationship with Fane. There is none but as this project comes close to a final conclusion, I would say there have been moments when Fane have been less than helpful. They had never men...

I am of course guessing, as to how you got the sound the way you describe it. This "off-set" might be pleasantly less then what I had in mind. It initially reminded me of an effect by having no impedance correction (Zobel) in a midrange driver, and o...

Putting together a speaker system that ticks all your boxes is a lot like doing anything else well: it is fine to experiment in order to find your range and learn your options but once you choose a path you must stick to it. Chopping and changing i...

In his latest YouTube,Romy mentioned using my prepro to time align my drivers.I use the Trinnov Altitude 16 prepro which has a total of 20 channels. 16 of the channels have balanced analog outputs and the othe four Channels use the rca and optical sp...

Glad to hear you have found a satisfying point so that you can listen to your system.Certainly the low bass is not as critical to your being able to enjoy the system, although no question there is much to be gained from that being optimized.Trying to...

[quote user="haralanov"] Take a look at the video: [/quote]I am not sure why you keep bringing the Vengerov’s video again and again. It is quite banal things and those infomercials of Vengerov educating in front of camera the sentimental girls ho...

ZZ, clearly, no single driver or pair of drivers can reproduce the range and power of an orchestra, and each of us deals with this according to our own personal demands and resources. The concern of this thread is trying to juggle/work with "phase" ...

Well, I was thinking that there might be something of a "shock wave" created if they run too low, and the pillows might soften that up, almost as though one were trying to get the horn to behave more like a direct radiator at LF, where there is not e...

First off, the crossover point will be 530 to 600Hz. the RES 1.5 midhigh is 16" x 8" x 10" deep.Keeping in mind, I'm trying to cover 600Hz and below... Given space constraints of a medium size basement room, I came up with 2 options.1st option is to ...

I would discard the first part of your post. It is it truly irrelevant what Germans, French, Japanese or Brits were buying and what particular brand and in what time they consider as “fashionable”. It is know that Ebay or Akibahara popularity has...

I see now. Quad can’t be driven by single 6C33C. This is well know fact and I did a lot of experiments with Quads and Lamm ML-2.0. For whatever reason as ML-2.0 drives Quads it produces Stingy Sound. I can’t explain it but it is not the sound that ML...

Sorry Romy, i can't tell you about life longevity of 6E5P in my amp 'cause i'm not using them there anymore :)For my speakers two-stage SE sounded much nicer, more balanced and clear with more volume. Well at least it was easy to predict, considering...

And email from a site’s visitor:….
“And for my full-range Melquiades, should I still try and build the original version or wait to see result of what you are working on now?”
This is a complicated question about 2-stage Melquiades vs. single-stage...

It is good, very good. Actually I did not expect that it would be so easy and some resentful at the same time. I was running the new horn, juts single horn, listing it here and there, trying to get a precise high-pass crossover point. The 18.5uF turn...

Thank you both for your thoughts. The space is interesting: not a cellar, but a sleeping area just big enough to fit a super king size bed, with one of the walls being half open, so it would not pressurize quite like a fully sealed room. Further, it ...

It is it, I eventual got what I was striving for a while and now my MF DHT channel is done and the most important is that it now sounds exactly how I need it to sound. The new 25:1 loading turned out to be the key. It is “fast” enough and I did n...

People frequently ask me what would be a good speaker to buy for $5.000, for $10.000 for $20.000 for $50.000 and so on. The more I think about it looking at the park of available loudspeakers the more I come to the observation that there are no good ...

Can we really say that the "lowest fundamental" from an orchestra is 30 Hz? I sort of wish it were true!Something I think we can all agree on is that hi-fi tends to suffer from lower fundamentals and harmonics that are not properly proportioned, and...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

Quickly again, for the record, and The Google:The back wave of the Manger has a much less flat response than the front wave. There are peaks out the back. It is not a symmetrical dipole. This issue is only of interest if you are using the back ...

Paul,I have not heard the synergy horn or any speaker with that design. Here is what I am talking about:http://www.yorkville.com/images/products/u15_cut_sm.jpgIn this particular case there are 3 mids and 1 tweeter driver sharing the same horn.This so...

I wish to construct a single horn speaker that might be used to explore Romy's amplifier design now, while not being useless within a 4-way system in the future (to be housed in a 5x5x3.6m room).I plan to construct it by pouring in a mixture of resin...

Arno, I have plenty at my site that describes in great detains why and what I do not like in idea of single driver with back-loaded horn. Build it and hear what you will be getting. The software you are irrelevant. There are no intended or not inte...

[quote user="morespeakers2"]The injection channel is the only thing about the Macondo that raises my eyebrow as a kind of "out there" concept and I have been meaning to ask about it for quite some time.

A horn basically directs acoustic energy in a single focused direction, maximizing the efficiency with which the air mass to moved by acoustic waves is coupled to the driver. The best thing is to read a good book that covers the basics in simpl...

[quote user="msaudio"]49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low ...

HelloI've always wanted to try an ESL as a horn driver:So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.Horn is old closet that had a trapdoor...

Josh, I am not sure what you want to say. If you looking to name the reason why you like the sound of Gotos then you are guessing as much as anybody else. I can tell you even more. I very confident that the Goto folks themselves are guessing. I do no...
