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...

Hi all
I have experimented a bit with rear tubes on compression drivers.
Chucked the back covers in a lathe and made a suitable hole
for the rear tube, matching the area behind the diaphragm.
Got "better" results to my ears with wool filled tub...

Hi all.....

I just wish somewhere would show up a manufacturer that would be able to produces compression drivers (or any drivers!!!) with sonic objectives…

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...

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...

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...

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...

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...

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...

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...

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...

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. ...

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
