Let do not forget that acoustic space also have own compression… not to mention that the performing intend itself has own “compression”.

Dear Romy,My speakers are semi active-I can turn of above 250 Hz- Do you think it's possible to just turn on bass, position them according to compression?Then fine tune by playing full range?Best regards, Armen...

Nope, I never heard about those
drivers. For sure a compression driver that goes down to 80Hz might be interesting.
A few concerns I would have however.
The people who make such a
driver would not come from nowhere but they rather would b...

Hi thereFor some time its bugging me that compression drivers got a very heavy but odd load of air coupling on the membrane. I saw a scatch here to put ideally 2 Horns on each side of the driveway to balance it. That's obviously not so economically :...

While my attempts at this stage are very crude by comparison (injection channel experimentation is not yet a main priority), I have from time to time listened more with a very crude sort of injection channel plugged into the system.
With this devi...

I have to admit that I was experimenting last night with Pacific’s Low Level Extension and it was not bad at all. It would not be my last words as I would need the whole system up and running to see what is going on – the region where the Low Level E...

[quote user="Romy the Cat"]I propose that soundstage is a derivative property of compression. Stripping compression destroys soundstage, increasing of compression makes soundstage more tangible. [/quote] Yes, I have no argument with anything you have...

A few days back a guy who began recently to use a power regenerators that eliminates a great deal of compression out of sound was reported that soundstage the he did not like did despair. In this thread I was advocated that “soundstage” as a surrogat...

[quote user="haralanov"] Also instead of using electrical tape, try to seal the back of the driver with a 2mm thick sheet of microperforated tonewood and then glue a leather layer over it. Then you could also pierce multiple tiny holes in the leather...

While seeking for a CD capable of covering a low mid range, say from 300hz or under, I am offered a pair of TOA compression drivers of rather impressive size. Unfortunatelly a seller has no clue what model it is, except "it sounds as seducing as ...

Hello,This is my first post to this site, which I have been absorbing for over a year.A horn project that I have been considering would include either a 1 inch or 1.5 inch throat compression driver into a Tractrix profile horn of which I have not yet...

[quote user="Paul S"]Romy, no doubt the following derives wholly from my ignorance on the subject, but I have not been able to get away from a sense of "variable compression" with any compression horns I have tried. By "variable compression" I ...

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...

[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...

I wasn't trying to critique Bert, or even get into an in-depth critique on the Swing, more Compression Driver configurations -- vertical vs. angled, and coaxial, (and maybe other factors which affect Sound). But I'm more and more real...

There are at least three benefits of using a compression chamber in a tapped horn design.1.) When using push-pull woofers with a compression chamber second order distortion is cancelled. This effect is very audible. You must hear it to understand...

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...

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...

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

[quote user="Romy the Cat"]Andy, my mind does not operate by the categories you employ, I rather think about nature of Sound not about harmonic/non-harmonic distortions. The whole subject about the distortion is intricate, not to mention that it is n...

Hm, Yes, I kind of forgot the idea of multiple compression drivers blowing into the same throat. I never was too warm to it but I do admit that it would minimize the length of the horn. For sure the right solution would be to make compression driver ...
