The idea of high quality delay makes me wonder if the delay effectively increases the virtual length of the room - allowing longer wavelengths before the room Schroeder frequency is reached. This would be a "softer" bass without the room compression....

No love lost for any particular driver type here. They are all all-but-hopeless, as far as I'm concerned, just for different reasons.Jesse, what I wonder is how the small daiphragm of the compression driver, with its very small movements, can b...

Hm, I was not kind of informed that Bluetooth in fact implies a digital compression. I was looking for some "High End" Bluetooth transmitter/receiver combos but they shall be all crap if digital compression takes place during Bluetooth transmissio...

First let me say I am NOT trying to promote the Synergy horn. I just think it is very intresting to look at and to think about.Ideal loading only occurs at a singular frequency within any horn. This ideal loading point is where the length is 1/2 a wa...

I would like to take my views about the subject of the thread:
Be careful: Imaging vs. Compression
… a little further into radicalism, or closer to the naked truth. It might be (and most likely) will not agreed or in some cases not understood, stil...

Yep, Stefano, it looks like we do have similar views about the subjects we touched. Let go back to exploring one of the terra incognito of compression driver – the sound of Goto.
I would insist is that to judge sound of Goto driver from the installa...

[quote user="haralanov"] The horns, even the fast opening ones are physically too deep for their mouth’s size, and this leads to a psychoacoustic illusion that the sound images are arrested at the bottom of the horn and from there they scream they wa...

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...

[quote user="Romy the Cat"]Of cause not but did you read and understand the Macondo
Axioms? The Macondo Axioms proclaims that an individual driver and individual channel
have to be set in maximum suitable for own topology operation. According to Go...

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 am missing something here, because to me this looks like a compression driver with specs that indicate it would best serve >10k Hz, yet it is... a compression driver. Maybe if it was backed down and run parallel with something more delicat...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain g...

FM is Analog Signal Processing vs DSP. The compression aspect is only really intrusive on orchestral works. Pop and jazz are already compressed and chamber music presents a more limited dynamic range if not limited contrast. But on the evidence most ...

I guess you cannot say you listened to a horn system if you dont have an upper bass horn.The upper bass horn has to fill in the response from the compression driver down. At this delicate range nothing will perfectly macth it but another front horn. ...

[quote user="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

[quote user="Crow"]The sound changed.[/quote]I do not think that sound changed. Those speakers have most likely MF compression driver with horn. When the camera shot from the back of the speaker the sound does not change. I mean is changes slightly n...

Here I would like to have a thread dedicated to a hypothetical ultimate MF compression driver. Use the existing, know to you compression drives as references. Any thoughts? The Cat...

I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....
|
|
That is the thing exactly, my upperbass solution has the same output amplitude as the compression drivers I am using, IMHO resistrors are the devil in xovers, they kill all sound. Now the difference between 109 db and 110 db can be overcome with c...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

I suspect that the 8" and 5" cones and 1" compression driver are in the Danley Signature Synergy multiple entry horn. This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an ...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

[quote user="Bud"]Just so you know about these folks. go to this site and page down for a bit till you find the horn installation topic. http://www.royaldevice.com/custom3.htm [/quote]Yes, the Royal Device’s horn is well know horn. Sure the enth...

Ygoh, Most of compression drivers have phase plug. A phase plug is very genomic center line oriented devise. A phase plug must be parallel to diaphragms and perpendicular to the axis of the driver. Practically all compression drivers have beggin...

it doesn't appear to me that Lowther's own designs hold any real potential.As some might figure, i'm partial to Voigt's original intentions, and i think those have been covered over.I post now because i had an idea.I see the lowther as a pseudo compr...

[quote user="ulf"] Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than we desired. [/quote]

[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...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...
