From historic perspective, yes we Americans are more responsible for what Bush does then Mozambiqueans for instance. A hundred years from now peo...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

[quote user="be"] "another big selling point to me was the 505 being a low resonance compression driver.. there just aren't many drivers with a resonance in the 80 to 100 Hz range like this driver... I have just begun my playing, but am already quite...

Let do not forget that acoustic space also have own compression… not to mention that the performing intend itself has own “compression”.[/quote]The question of 'self-compression', where the performer moderates their perf...

We, the horn people, know what the compression drivers could do. The controlled dispersion, low distortions, low mechanical dependency, low magnetic anomalies, high efficiency, higher maximum dynamics and many-many more advance are well known. The te...

[quote user="Romy the Cat"]One of the emails that I receive is very interesting. The author warns: “...when experimenting with throaths I found that if the compression is big, near 2 or higher you get some big, smooth, unfocused aqualung sound. You...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

One might think that the BMS coaxial compression drivers might be especially coherent and superior to the dedicated mid-high solution, but I find there is something wrong with them (and I don't belong to those who dislike the character of BMS drivers...

[quote user="Michaelz"]Some drivers have a rising db curve from low to high frequencies. The horn may help with flattening the FR. If the FR of a given coaxial compression driver is flat, I would agree with your conclusion.[/quote]Mi...

[quote user="horny"]… me too would like to achieve as good as possible violin reproduction without spending a fortune on exotic or vintage drivers.[/quote]
I have voiced my frustrations about many contemporary compression drivers. People who manufac...

Hello John,The woofer is Fane Studio 8M and throat diameter on the 115Hz horn is 5.56".The initial 4.5" depth of the throat is made up by 6 MDF pieces with rough edges (awaiting bondo smoothing).I can easily add 3/4" pieces to the throat section to m...

I was right before but now I really review my rightness for a new perspective. Yes, the compressions drivers are the subject of clean signal but it what I witness with the new 6-chenals DSET put what I said above in another extreme dimension. I do no...

Thanks, Paul
I have seen your comment about the TAD bug screens at AA. The bug screens are a touchy subject – with some driver removing them works fine with some made sound worse. I did not experiment with TAD’s bug screens…
Generally the bug scree...

Yesterday I spoke with a guy at a Russian audio forum who reported that he played with addressing many problems of compression driver by pumping ferrofluid in the gap. I am not a big fun of ferrofluiding generally and in case of compression drivers i...

ATTENTION SOUND ENGINEERS
Dear sound engineer,
As you certainly know, a recording that sounds BAD on a "high-end" or "audiophile" playback system may still sound GOOD or at least acceptable on a the average more modest mass-marked systems (such a...

Correction :
In the previous post near the end, I should have written as follows:
The other day I tried letting the 180Hz lower-mid horn do more and the 400Hz upper-mid horn do less, by moving the crossover points up (I do not attenuate the low...

To assess how far audio imaging from sound of a ”live” musical presentation we need to subtract visual experiences from perception, including the long-lasting visual experiences. I would agree that focusing ONLY on imaging can lead attention off beam...

Hi jd*,Unfortunately the minorities always get screwed and this case is not different.Most people out there listen to music as a background or head banging noise, there's no way around that, and wide dynamic range is not compatible with this.It would...

Xandcg, these bass compression drivers is a controversial
subject. T think there are 3 of them ALE 160 and P1260
and GOTO SG-146LD. I think they all 4”, it would be very nice if they were 6”.
However, 6” exit might be a bit too wide for compre...

I spoke to the owner of the company. The drivers are copies of Western Electric 555 (but the owner insists that they use genuine NOS WE diaphragms membranes) but they can be custom made to fit in with one's requirements. I didn't know such a thing wa...

I'm of the opinion that listening room aesthetics play a big role in enjoying music at home. This is self-evident, but over the many years playing with audio, my listening room has become incrementally cluttered with "audio detritus". It's ugly and...

One more tip. The “least dynamic compression positioning” mostly managed by upper bass and bass channels while in the “imaging positioning” the MF and HF channels play more dominating roles. Therefore, if you use a typica...

Crossing the woofer so high is not really a fair comparison. The compression drivers needed to be in a bigger horn, and possibly be replaced with a driver that does 100Hz for certain. ...

This was noted on the Yahoo FMtuners site and is an interesting, fast read on compression at WCRB:http://www.thebdr.net/articles/audio/proc/ClassicalAudio.pdf...

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...

Collin,
I do not remember that I wrote that Trios are “duller”. In fact I do not remember I ever wrote anything about Trios in comparing to my current hors. Furthermore, my “Macondo” derived for the Trios and practically fully inherited the Trio’s ...

Hi Romy,Your the first person that I have seen that seems to have actually made PP tube amps work with compression horn drivers. It has been my experience that PP amps don't like the low watt operating range. I supose it all is a matter o...
