Your rules say no direct answers so forgive me this one.

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...

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="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...

[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.

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.

I had a feeling there was no easy answer, wasn't sure if I was missing something, had scoured posts for a whi...

I also got tired of reading all the DIY posts on the S&B 102. And yes, I have done the numbers, and it would be possible to adversly affect bass with high impedance feeds and/or long, bad cables feeding this unit, coupled to ...

I do have a speaker with a flat impedance. It is an Apogee Caliper Signature with an impedance variation from 3 to about 4.5 ohms over the whole range. Fortuneately it is not so dead as your example as it has about 86db sensitivity. ...

http://www.webbtjanst.se/lenco/loudspeakers.asp shows some photos of unfinished horns. Comments on mouse-over.The 250Hz horns are probably not super optimal since I'm crossing over at, I think, around 1600Hz right now. Yes, the little horns...

I do not why hell they do it but and it is become almost painful. The MET’s FM broadcasts become more and more compressed and they increase compression monthly, literally monthly. I am listening now the MET’s second act of La Boheme but it is too muc...

Ive tried various configurations but was unable to produce a recording that is similar to the fm transmission, although its not too terrible. I monitor the sound by using the same output of the Sansui that goes into the DAW. Replaying the file, I n...

I have to say, that I genially like the new 99.5. I do not have as perfect reception as I had with 97.9 with absolutely clear, no noise background. Still, thankfully the compression of the new 99.5 is very low and last night and today live broadcasts...
