Pierre, yes, I understand it. It kind or irrelevant what they destined for and yes, in domestic applications in context of low power we can use it lower. What I am saying is that as we do use it at extreme low range we deal with slightly overdamped d...

[quote user="Romy the Cat"]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 t...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

[quote user="rowuk"]Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the a...

Jorge, if you have 120hz horn with a 4" throat and 10" driver then Fane 8M would be a good candidate in my view. If I were you then I would try. The SG146LG is you had would be very interesting to try as well. Not to try it stupidly as most of Go...

[quote user="Romy the Cat"]If I succeed to make my midbass horn at attic then I will face another problem that I do not know how to address at this point. The horns will be powered from Melquiades bass channels – it means it will use a good 70 feet s...

[quote user="Mark Donahue"]Mani, Yes, the files were created using the HDCD Model 1 AD converter and you will actually get improved audio if your DA converter properly decodes the HDCD (Even at 88.2 kHz /24 bit!) There is information about the filter...

[quote user="tuga"] Don't you think that this “soft reading” players with no rythm syndrome could have mainly to do with dynamic compression, which is as much a feature of many "analog sounding" CD players as high frequency roll off?[/quote]

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...

Anthony, it is not the subject of this thread but I am replying you since you raised a question. Is there are a lot of conspiracies about Tannoy vintage crossovers. They did many different versions and all of them well known. If somebody need I can h...

I do not remember whose inhalation it was, also unfortunately those audio people flash each other with pictures, exchanging with audiopornography, but do not share their reason, thoughts of objectives.

[quote user="Romy the Cat"]I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you.

A few months ago a reader of my site contacted me and informed about that he found a very interesting driver, that his is using and he is very excited about it. The driver is JBL 2490.

Hello again, Romy.. let me see if I can clear some of this up....
first, you are indeed correct on your horn thoughts.. but some clarification is in order...
Ming Su is the importer of GOTO to the USA... Goto Japan only ships horns from flar...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

Thanks Romy,
I would have thanked you sooner but I had the day OFF of my day job today and had no time to post until now.
*cracking up*
I had a feeling there was no easy answer, wasn't sure if I was missing something, had scoured posts for a whi...

No system ever resembles live music. imho. But you can get pretty close.Can you describe or share a pic of the horrid horns systems you have listened to?I also hate most badly designed "horn" systems too.Usually most "Horn" systems have a 15" woofe...

[quote user="ShuffleSk8Ter"]there is one system that resembles what live music sounds like and its not a horn! To be honest I really have no idea of what topology these horns were setup like... all i have evaluated is there soundI like to go into som...

Hi rowuk.Shark skin decreases the formation of vortexes in fluid flows over surfaces and thereby reduces drag.Shark skin resembles fine sand paper and has actually been used as such.Of cource there is a difference between a stady flow around a shark ...

Well, correct me if I am wrong, but I would say that imaging relaies heavily on the differences in timing and amplitude between the two sides and with secondary reflections. This leads to a perception of sound wherein we are able to localize in...

Hello RomyI like Shelters as well, so I finally scrubbed-up enough money and began to search. I was always happy with 901, but there were none around. Last night I got a 90X, with (supposedly) around 100 hrs on it, within driving distance. So today I...

Practically, a modern orchestra plays more "safely" for a recording. This most certainly limits the tonal palette from any or all of the instruments. There is less for audio to reconstruct.If we are talking about more "vintage" recordings with a gain...

I understand that "nothing changed in the horn dimensions if you go from between 10" and 12" driver". You are referring to the horn mouth I assume. Do you have a idea what compression ratio is good to have for upper base horn? It seems that 2:1 is ta...

Well, I have just taken receipt of my Orelo speakers (pic attached) - the bigger version of the Orelino speakers, with 3x 15" bass drivers per channel as opposed to 3x 12" drivers.I realize that Romy doesn't regard the coaxial BMS mid/high compressio...

My work to make the Fane S 8m work, continues amd I have yet to hear my midbasshorn built perferctly according to Romy-specifications. I will continue because in early trials there was something I did like. I guess I will just end up with a measly €...
