[quote user="vinylithicum"]Hi audiofilofine.Nice drivers, although the picture is a bit fuzzy. Can you tell more about your drivers?Maurice.[/quote]All parts of the tweeter shave been designed and built.All are built in magnetic steel in preferenceto...

The AudioFederation guy posted pictures from RMAF show with Cogent room. (The images are courtesy to http://www.audiofederation.com)
I was wrong in my previous post, as Cogent did demonstrate their loudspeakers with Ionovac ion tweeter. Yester...

I was captivated by the extraordinary Acapella tweeter at CES this year in their Violon III speaker demo...I think I had heard a version of this tweeter before in a different acapella speaker, and never noticed it as being wonderful...but t...

[quote user="mark"] just would like to clarify the cost of this ribbon,xfmr. etc.the figure of 2600us$ is that for tweeter pr. only or complete with the xfmr.?i got a quote of 4000 euros +300 ship in jan./08.has the material cost risen dramaticly sin...

[quote user="Johan Dreyer"] I had a SG370 mid apart only yesterday.I should have taken a photograph. I have also seen the inside of the tweeter. They are very similar, so I have no reason to suppose the low mid SG 505 will be much different. I'll try...

[quote user="haralanov"] The ribbon is 100% tonally … If you use this tweeter lower than 10kHz your system will be totally unlistenable because you cannot reproduce the proper tone of harmonics.[/quote] It is pretty much what I found as well during m...

judging from your draving, they appear to be bipolar operating tweeters and not dipole. While I generally do favour the horn approach above all the others,sometimes I do wish the whole reproduction would be less "dry" and bringing in some wide beamin...

Hi Romy, I agree with you that most speakers have some tilt-up treble response, maybe not on paper but subjectively so. I think this has to do with "beaming" of the tweeter. In real life sound in general (high frequencies included) becomes weake...

Romy's quotes in blue:"...It feels that there is very little room for the tweeter to breathe. It is not the narrow firing tweeter and I think you might give to it a little bit more room..."Yes I was thinking the same thing, and the frame does offer p...

My favorite were the Classic Audio speakers. I know they have many faults, but the Fostex 500II tweeter was singing nicely. ...

agreed with your comments about the show. I go mainly for the record shopping as the local record stores bring out their better records. I picked up several excellent box sets, including Webern and Bruckner coral music. I also went to see the Airforc...

Romy,Interesting video. The first thing that came to my mind when you were talking about HF colours and the "clean" RAAL Waterdrop tweeter, is perhaps adding colour to the RAAL. Instead of blanding out the midrange S2 and injecting HF colour with t...

|
[quote user="anthony"]There should be an 111dB tap on the Lazy Ribbon, but perhaps you have tried that already. Other than that, perhaps talk to RAAL to see if they can improve the sensitivity a little more with a transformer change (or something el...

Thats the kind of stuff I was hoping for. I appreciate the help with this, there seems to be a scarcity of horn related discussion on the web and its proving hard to learn the ropes.One other unrelated question that could save me a lot of trial and e...

[quote user="Romy the Cat"]audiofilofine, you need to form a question in a format that would indicate you do the your do some homework. To bulb or even to design 20Hz horn is complex task and it usually made to the specifics of the given circumstance...

Hi Romy,
Again, good words (don't want to kiss your ass ;) ). Though, I get your point and agree, one should not think that this winter picture means Goto sound cold (u never know what one could read out of it) .
What Klaus also highlighted, is...

Another tool used by sound pros is LEAP. The guy who designed my BassZillas (some time ago) used this tool to make the most of a BR enclosure. As for the Fostex (U)HF, the pros tend to correct them digitally, as they need "something". Mainly, did you...
|
|
Ok, I think it is it. I close the experimental phase of the MiniMe projects as I have selected and feel comfortable with MiniMe results. The MiniMe Bass section is the very original MiniMe enclosure with the very same drivers as I plane from star...

Now first of all our ears were designed to hear up to 20,000 cycles there-abouts if not perhaps more, a scientific fact I can't really argue against. So I find it difficult to accept a proposition that we don't enjoy listening to sounds from 2,...

Morning,I'm not disputing what you heard, but your conclusion that the LF must modulate the tweeter section can't possibly be right. 0.047uF is a -3db rolloff of 34Hz. If you're saying that over 0.68uF was fine, then by implication 0.47uF is not as g...

[quote user="Romy the Cat"]You might change your mind after you put the PP2000 into the game. Anyhow, I do not know what Bruce did with his Titans tweeter; I do not even remember it they are in time-aligned position. The EdgarHorn Titans uses Fane ST...

Maybe it has some interest but:- Backloaded bass horns- 2" midrange driver with Beryllium membrane- 1" tweeter with Beryllium membrane- 0.5" super-tweeter "a la beryllium"sounds quite worrying to me.Nothing is said about the upperbass channel dr...

[quote user="Romy the Cat"]Anyhow, now it is officially: I permanently removed a tweeter from Macondo. [/quote]After a few days of playing my Macondo without tweeter I begun to think what is goingon. The S2 eventually works clean and without any hars...

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...

Ending up re-amping my MF channel, I found myself at unexpected situation that I am not completely compostable with Macondo HF. It is not that the HF are bad but they were made to serve the interest of older, slightly softer operating single-stag...

Very nice mounting. Hopefully the ridgidity will not cause any other unwanted vibrations from moving the assembly ever so slightly. I doubt it could be heard if so. Having used the T-350 (and t-35) over quite a long period from the mid 70's through t...
|

The ribbons surely do lack "qualities", but we are talking about serious "HF" in this case, and who says real HF actually wants "qualities"? I really doubt that any "tweeter" that can do "stuff" can also do what the ribbon does best - in a class...

[quote user="Romy the Cat"] The tweeter is sitting at 1.5K, first order. That is king of low crossover point for tweeter but it is OK. The problem that I see that with this time of the filter and a compression driver used I think the horn for th...

[quote user="Romy the Cat"]Now my midrange channel need no upper range diffusion and now I feel that the result I’m getting from T350 is too soft and too transiently slow for S2. So, I kind of very mildly begin to look out there and to try top fugue ...
|

This is quite recent conclusion, as I sick and tired to do not say it finally!
A loudspeaker must have a volume control that will adjust an amount of HF that a loudspeaker radiates into listening space. I playback systems that has an excessive 1/3 d...
