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....

Nice to see someone actually try it. I know that fast rates "work" from MF and up; but I have not tried it with compression drivers/high gain/LF.Thanks for sharing.Best regards,Paul S...

Hi Romy,I do not know how much experimenting you have done running a compression driver with no LP filter through your 250Hz tractrix. However, in consideration of a given driver employed, irrespective of adjacent channels and by your various criteri...

just got it that you meant the diameters,of course its around 65%. i always calculated the throat-size with the area....i really would like to get a second pair of s2´s but i think right now it would be difficult even if i had the money;-(((if i go f...

You need to decide what length of the horn you can afford. When I mean “afford” I ment the position of the horn in context of the rest of your system. You know the lowest cut off - 40Hz. So, the most suitable for you length and the mouth size will gi...

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="Murataltuev"]So, the question is still opened: how to get 300-400hz.[/quote]Perhaps give the JBL 2169H a try. It is supposedly very good from 300Hz to 2.2kHz, but I have never tried it. Use it in a sub 200Hz tractrix horn with a 4" thr...

Hi Skushino, hope you dont mind me jumping on to your old thread, but I can upon it while looking for ideas re chamber volume and compression ratios for the same Faital driver into a 160hz Azurahorn. Could I ask how you were using yours? Ta,K.S...

Hi Be,the thread is about the "bad" reputation horns have with "audio" people. Applying liquid dynamics gives them more fuel for the fire, that is why I avoid using stuff that really doesn't apply. We have no real flow of air or "turbulence" in a hor...

[quote user="guy sergeant"] There's alot to learn putting a new system into an unfamiliar room. [/quote] …and I would add: the unfamiliar drivers with unfamiliar amplifiers. It is trippy how SET amps could be loaded with different drivers and produce...

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. ...

Well, I think it was juts a bad translational as some of the things they said in there are so off the wall they it sound as they were written by a 10 years old. I more interesting what 3” compression driver they used… I wonder if it is 3” exit, or 3”...

I do not have lot of experience with TAD cone drivers but there is a thing bout then that always afraid.
A few years ago I was at demonstration of Model-1, the TAD’s $50,000 flagman model and it had very strange feeling – the speakers sounded surpri...

I understand your position on compression and not wanting to screw up the tone. The Community M4 driver is the perfect example of how NOT to build a 4” exit compression driver. First, the cone/dome material is garbage. Neither the sandwiched aluminum...

I never heard it or about it but here is data:

It looks like it has CB horn and aluminum cone in pl...

Part 2 – Description and explanation
Anyone who have ears and a rudimental mind to understand what ears register, and anyone among them who played with MF channels driven by SET, know that subject of SET loading is imperative.
Let take for...

Hi Romy,
When we spoke at CES, you mentioned that your experience with field coil drivers only extended to cone types. So I assume that you have never heard any field coil compression drivers. That would include the WE 555, 594, RCA 1428, Lansing, e...

I wonder how far one could get to the traditional horn ideal (low-ranging compression driver plus some metal shimmer on top) with a BMS neodymium pure mid driver and a Celestion/Eighteensound/Beyma with aluminium diaphragm.BTW, something with berylli...

Hey Romy... you could be right about the ALE's.. I certainly did like them, but when I went back to that familiar recording it was definitely shelved down low.. it would be easy to assume that I thought that they were "lightweight" because I had...

...Or plug all but the desired LF exit path? This might not have the same compression ratio a stock though. Well, I am still learning about how phase plugs operate.Neil...

Romy:I have worked at WHRB (and now outed myself) and I know these people.They, like all college kids, have no understanding or awareness of broadcast quality at all. When they max out compression, and I do mean this, they may not even know they are ...

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...

[quote user="be"]"the cavities behind the coil are not the cavities where pressure passes"
Yes, but the speach coil and diphragm can "see" the air volumes behind the magnetic gap and will be loaded by the resonanses created, and the radiated s...

… and now I have already just a few minutes into the Orff (boring so far) but have already two calles about how good the Prokofiev Classical Symphony was. BTW, the WCRB looks like dropped compression a bit now I have very ugly reception…. Watch tomo...

I can hear the whole of Mozart's 35th and Bruckner's 5th and to me the Bruckner 5 performance is very good despite the awful compression. Good enough to go into your "Recording Of The Week" section.I also wish they would release non-compressed files ...

[quote user="Chirag"] Still, I do miss the dynamic lower MF of the 15" woofer...[/quote] Well, this is it. I really do not know what it is and I (and you) call it “dynamics” but it might be something else that juts appears like dynamics… I did not pl...

My Shelter is set properly; in fact the setting was not changed for years. On my TT there are 4 arms and there is another stereo arm. I know what shell be difference between my Second stereo arm and my Reference arm. No my Second stereo arm over perf...

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...

I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also. I was joking with a...

Roman,I don't think I've ever read your explanation why not 2482? We are all on a holy grail path to find a (somehow) available good compression driver that can go down to almost 200hz in domestic conditions and there are not many better candidates. ...
