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 did not like the two slit configuration of the phase plug..but the five to one compression ratio produced low distortion,,,but i was not impressed with its bandwidth,,,JBL also used a eight inch speaker assembled to a special phase plug,, You will...

[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...

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...

There are two YL Acoustic Compression drivers flying around:
D-5500G, .6” lower MF, 100 Hz -7000Hz, 15W
D-3500G, 1” upper MF, 500 Hz -9000Hz, 15W
They are YL are pre ALE driver and they might be interesting for somebody who would like t...

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 ...

I was listening last night a string quartet rehearsal. The play was for the most part justifiably non-so-glorious and I was thinking about my little audio things. For sure our upper MF drivers nowhere near where they need to be. There is too much...

Just a quick note.I tired a JBL 3" compression driver 2490h model with original Titanium diaphragms on a 120 hz Tacrix horn. I got a response down to 200 hz. How did it sound? It sounded good clear and transparent but it lacked a little tone imho...

John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

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...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

I do not know what the satellite radio in Europe, I know that you have a different system in there but in US satellite radio in my view has no bases to talk about better or worse tuners. This is digitally compressed signal, so what is the difference…...

Fascinating stuff. I'm certainly going to try to get my
hands on some 2440's when I can see them for a nice price.

using currently manufac...

Hi Ronnie, There are a few things that could be causing the alien sounds you site. One, of course, could be certain frequency nodes being excited by room reflections. As long as your room is reasonably dampened, this would not...
