[quote user="malinowski"]TAD ET-703 LinkMAGNETIC CIRCUIT. A high-energy, rare-earth cobalt magnet is used in the magnetic circuit that, together with powerful soft iron for the pole yoke and plate, provides a high magnetic flux density of 20,000G.[/q...

I came across an article:http://www.ultrahighendreview.com/enigmacoustics-sopranino-super-tweeter-review that introduced electrostatic tweeter that might be interesting. The company has a web site that is to unpleasant to reread/navigate: http://www....

In one if the Brits forums rowuk wrote
about Linaeum diapole tweeters:“Give them their own amplifier, then the efficiency does not
matter. Great amps are not that expensive and with the standard distribution of
acoustical energy, the tweeter does ...

[quote user="audiofilofine"] All parts of the tweeter shave been designed and built.All are built in magnetic steel in preferenceto pure iron because pure iron is heated during processing and after processing was not possible to check that the charac...

Leaving open the magnetic flux to the nucleus is smaller and therefore the tweeter sounds much slower . All the tweeter is in magnetic steel ( except in some parts ) but the magnetic force is concentrated on the core . Since I use a translator to try...

user="anthony"]Romy, I'll be digging round in my amps tomorrow and
intend to install a filter for the red tweeter while there. What should I
be aiming for? 7kHz first order from memory, but hoping you can
confirm. Such a filter could be...

A moron would ask - is the best tweeter that I heard? I clearly have no idea and do not view the things in this way. A tweeter is not a self-contained element but it is an organic ingredient of the rest of installation.Rg...

Another very interesting aspect of the Water Dropping of Macondo is a dramatization of silences and influence of LF decay. Macondo has no own noise and the Super Milqs are dead quiet. However, the perceptions of silence with the Water Drop tweeter an...

[quote user="Merlin"]I find it pointless discussing the "sound" of a drive unit as it will be totally dependent on the implementation within the system. [/quote]
I disagree. It is pointless discussing the sound of badly implemented drivers but if a ...

Here is another very interning solution to compliment S2 driver with top end. Townshend Audio have their Ribbon Tweeter with reported 110dB sensitivity and price of $1500.

After several tests of listening and somehow I felt that the best solution is fully closed. The heat is part of the project and not to damage the diaphragm, also the hot air is compressed better than cold and thus distorts less. Even leaving the cont...

I have no idea what this Tweeter is. The reference to the aerospace aluminum alloy and Lamborghinis very much suggesting that the tweeters are crap and the guy who make them an idiot. But will not be too fast with conclusion and I am accustom to see ...

Ahm, I thought, that the midrange horn loses its directivity after 7000 and thats there I need the h-105. By the way its the only ring radiator from Coral. How can I add at the same time a first order 10k and 5k to the same driver? I always thought t...
|
|
[quote user="rowuk"]I see a problem with any „coaxial“ attempt in one horn. The length of the horn is correct for one band, but not both HF and MF. If the horn is optimized for MF, if is too long for HF and works like a transmission line at those fre...

I kind if cycle my attention on the notion of compression and it is not accidental. When a few years ago I used the hugely dymick NT51 tweeter in my car I experienced problem to set the right volume and I run the volume control 10 times more fre...

One possibility is that the midrange to high frequency domain has very large suck out (no pun intended). The priapic horn with its aggressive high pass might be a "filler" device to amend the 2nd order electric dip in frequency (Linkwitz-Riley alignm...

[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...

It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. They already had splurged for...

I put a couple days ago a silk dome tweeter in the game. I look in my storages to see what I had there among the traditional silk domes. I ended up pulling out my North Creek Music D25 driver.

I left the SA8535 burning for entire day and nigh, driving it with HF “torture” signals. Interesting that the driver become much more civilized with those “alien sounds” completely evaporated. Honestly it become to sound much better… but at the...

when I see a playback installation that is flat to 20dB I feel that this installation
was rather a mechanism to malice people. If yo...

One of many issues with dipole speakers is directivity/beaming at HF. I have been firing multiple paper tweeters at various angles on my OB test mules with varying results. Here is Alex's idea for a dipole ribbon:https://www.madisoundspeakerstore.c...
