When two years ago JMLab introduced a new flagman of their home loudsapeks – the Grande Utopia Beryllium the Worlds was shocked to its foundation. Our reporters rushed to interview Jacques Mahul, the JMLab’s CEO and designer, and let him to pre...

[quote user="el`Ol"] I know the PAC tweeter of the WLM has the best transients and transparency of all tweeters I know and so is the best tweeter above 5kHz I know, although I hated the implementation (crossed far too low, harsh-sounding upper midran...

I generally like what the Polish people did. Of cause from sonic perspective their system with misaligned tweeters is unacceptable but I very much like how they curved both midbass horn and tweeter fame – very tasteful. Design-wise in this configura...

I think I have too much time on my hands or use my time in highly stupid fashion but I decided to do today the experiment about witch I was thinking for a while. The experiment was “methodology clean” and lead me to quite interesting discoveries. Sin...

Yes, Paul, I know this company. It is always slightly annoyed me that it is Chinese company as Chinese manufactures very rarely, if ever, do any audio products with extreme or demanding performing characteristics. They rather do inexpensive mass-mark...

Just put a few fake silk dome tweeters out there; the kid will go straight for them and leave everything else untouched.jd*...

Hello Romy!I have been into the topic of indirectly firing speakers for a while, starting with highly dirictive fullrangers directed towards the ceiling. I don´t know whether you are familiar to Stig Carlsson´s speakers. Probably the older Sonabs wit...

[quote user="Romy the Cat"]...To substitute SL600 original tweeter with anything else, would it be Revelators, Diamond or made from Faberge Eggs is like to make a movie with Humphrey Bogart and ask busboy form a nearby Chinese restaurant to re-record...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

The visitors of my site who have read my observations about the CES 2005
http://www.goodsoundclub.com/TreeItem.aspx?postID=1918
are familiar with my very positive impressions about NESPA Optical Disc Finalizer.

Sine I finished the acoustic room treatment and the final setup of my playback in my new room I got good Sound. There are some minor aspects with which I will be working on – I know exactly what I need to do but they will be minor and incremental...

Roman.
This last "venture " of yours is most welcome .A lot of of the people I know and most of the listeners from audio shows are always surprised when small monitors produce big bass and try to
impress with big sound. I never liked this "pushe...

[quote user="Jorge"]I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As ...

Haralanov, I guess you mean to say disconnect the tweeter on one side of your playback? not the whole left side of the playback...When you use compression drivers it is very important to design the horn taking care of the high frequency response. ...

Charlus,As you expressed here this would be an End of life speaker project, and I am sure you will not fancy any other speaker once you start with this, even Vox Olympian etc. Yes it will take a lot of money and a lot of time, but you will have fun...

Well, it looks like my lack of familiarity with ribbons/planar/isodynamic tweeters made an evil joke with me as the more SA8535 tweeter getting broken in the better it sounds. As now, after near 80 hours it practically free from any negative things t...

Sucks! I made today my conical prototype and loaded it with S2 band-crossed at 500Hz and 900Hz. Pretty much wherever I placed this horn except directly above the tweeters it screwed imaging. To mount it directly above the tweeters does not look...
|
|
It is my understanding that the only reason to make a ribbon bigger is to get it to go lower in frequency. I don't know how Arum Cantus configures their G1, and I have not heard it so I cannot say if it is their "best" pure HF driver rather tha...

[quote user="slowmotion"]But not everyone agree with you there, Romy. If I could make the directivity reasonable constant through the frequency range....all the way down.... An array of tweeters is the last thing I would do.... [/quote]I disagr...
|
|
[quote user="slowmotion"]How was the lower midrange affected by the tweeter removal? [/quote]Now the S2 is crossed at 700Hz with first order where the upper bass begin to dive. Since I use now a new line-level (yes my buffer project is over quite suc...

Well, Steve, usually I find this situation of “instantaneous awe” is not necessary a good thing. You did acknowledge the “benefits” of the tweeters in Acapella and this is undeniable evidence that the tweeter did not perform well in context of the gi...

[quote user="Paul S"]Again, I am NOT a collector - at all. I am only in it for the music[/quote]I am not a collector too. I collect some very specific drivers only to take some good parts out of them which are not available anywhere else. I do not c...

I have seen those old Telefunken, Siemens and some other 4” cone direct radiation tweeters, but I never tried them. I do not know thier signature and I do not know thier characteristics. The reason why I never cared about them, although I might be wr...

In my observations about the SEC 2006 I associated the high-end industry with a strip join. Continuing this thinking I have to admit that Srajan Ebaen’s 6Moons.com site remind me a strip join with inflatable robotic girls. The all girls there ar...

I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...

I very much like he graphic illustration of the phenomena that Haralanov is trying to advocate but I very much disagree with Haralanov conclusions. The integration of HF MIGHT and MIGHT NOT have the effect that Haralanov described. The effect he desc...

Well, I do have 3 channels of DSEP. Dedicated Single Ended Pentode: one channel (bass/mid 30-500 Hz) with a 307A DH pentode feeding two wonderful Fane neodymium Colossus 12" - one from FS to 150 Hz and the second from FS to 500 Hz. OPT with a lot of ...

I noticed quite a few speakers, various configurations, that sounded more like a collection of nice drivers wired together that what I would call a "speaker." I mean that you could clearly hear distinct tone, character differences between each ...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

Gregm, you see, the Murata tweeters have no sensitively and vary narrow diagram and that makes those type of the drivers unusable, even if to accept then hypothetically. With the resonant frequency over 100Khz that those type of the tweeters beg to b...
