[quote user="haralanov"]Ironically or not, I have no practical problems with it, simply because I’m not using big UB horns. My upper bass channels are much more compact – 4 very massive 15” drivers with no horns. Their integration to my main widerang...

[quote user="Joe Roberts"]The illusion of a single source is lost. [/quote][quote user="Romy the Cat"]The “single source” neither is a fact a byproduct of a specific sound reproduction method but it has no existence in LIVE sound and there is not nee...

CV, Good scenario as well but my leading idea is slightly different. I would like to keep any reactance from the path, would it be inductive of capacitive, to assure ultra fast response time. Basically I would like to maintain the MF amp as it used ...

Interesting concept but let me point out a few considerations.The diffusor does performs a mild "equalization" function if you want to call it that but it is also an aid to dispersion. It is light "EQ"...3dB might be about right. Without any diffusor...

Dear Romy,Assuming that your questions are "honest" ones ( I have no reason to believe they are traps, like it happened to me before with a certain Mr. Thor), I will give you "honest" answers, hoping that our dialogue will be of some interest to the ...

[quote user="HookEm"]But, although it seems things are moving in a good direction, the overall presentation still seems a bit dry (not as fluid as my head tells me it should be).[/quote]HookEm, it was a bit is very generic comment that does not expre...

Hey boy,is it a kindergarten,"does not change anything"you don´t understand my construktion, your are not able to interpret measurements and simulation,if you are so blind, to see and understand,why do you post, little boy.it is so boring. read again...

Ok, I do not know what it was: was it DHT, was it 300B, was it some other specifics of this given amp or whatever… but those two aspects that I named: intentional density of colors and randomness of pace are something that I would like to exercise in...

[quote user="Paul S"]OK, I think I get it, except you will have a sand bridge along with your crap-load of Farads guarding ground, and your PS out feeds all six "channels", including the DC MF without dividers? [/quote] I will use the same trick ...

Hey Rom etal.I'm entering into unknown and difficult to intuit territory for me.I aquired a pair of very large constant dirrectivity horns EV hr9040 a, a little while ago and i now have a pair of jbl 2420's to power em. I haven't put them to gether, ...

[quote user="cv"] That said, I do have is a single 160Hz/1.5" finally up and running on a compression driver, and it's a different world - stunning. Actually the results are exactly as JJ described. [/quote] The JJ, is it Jeffrey Jackson? I have no i...

Very cool, the more “hornier” the better as far as I concern.

A few questions. What driver is it? It looks like it is 15 Vitavox, is it 151 or 15/40? What the resonant frequency of the horn and driver with no back chamber? The most important: how the hell all of it sound. I do not be believed that you did not h...

[quote user="guy sergeant"]I will ask. As anyone could by sending an him an email or calling him. Ultimately though it'll be because that's what he felt worked best. [/quote]
Well, it is a bit more complex then what you wrapped up in your la...

Last week I listened to some small back loaded speakers using Fostex drivers where the cabinets had deliberately been made to replicate some of the qualities of a double bass or cello. Apparently very thin cabinet walls etc.While I have some reservat...

Dear Romy,What would be your suggestion on the operating point and OPT impendance if I were to drive a single driver Back loaded horn speaker with over 102db/W? Knowing that you have mentioned a range of operating points in the forum, I still not too...

Once you figure out where you want the LF drivers you could put them in a "cabinet" of lesser dimension and run that "cabinet" through the floor, using the basement, or part of it, for more volume/IB. That could "solve" the IB footprint problem, and...

I was searching for an answer why squire wave is so screwed and I was advised by the site’s visitors that it is due to HF restriction of my channel. My HF response does look too low to me – the 23kHz; with all my ultra low capacitance magnetic I ...

Hi guys and gals! Glad to have found this site!My question is do you believe in single driver speakers like Cube Audio? I don't need ultimate low end extension but accurate mids and highs. Thanks ??...

[quote user="HookEm"]The reproduction does not seem natural... too far away from what I would hear at a live event (e.g., female vocalist). Sort of bright and fatiguing at times. I may not be using the proper terminology to describe it, but I do...

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...

This weekend if I have time I will be doing the testing of my driver deciding which one I will be using. The framework of testing will be the following: a single driver, closed at 150Hz first order, mounted in infinite baffle and working along with M...
|

Thank-you for the detailed response Romy. I can understand your reasoning.I have noticed that there are several commercial horn offerings that push a wide bandwidth through a single horn (eg. Martion Einhorn 370Hz - 20kHz, BD Designs Orphean MKIII 2...
|
|
Robin, of course I meant to say above that the Heils are equivocal when pressed, and no reason for me to think a compression chamber mosh with another driver would improve this quality; but I am just guessing. It would certainly be interesting i...

About the bass, which must be lacking in such a construction:I once made an experiment with something similar (single "cut" horn with "mouth" directly adjacent to the driver), and subjectively there was much less bass extension when I placed a barrie...
|
|
The Fs resonance does have its width BUT that means that the 30 Hz PR resonance out of my example is excited when the driver is not exactly at 30 Hz (not that a 30Hz PR can resonate at 32 0r 28Hz!). By definition a Helmholtz Resonator has one frequen...

Try thinking about it like this: Moving your ears 1/2" closer to all drivers in the system is not the same as moving a single driver 1/2" closer to your ears.jd*...

You know, extending the front baffle without making it take up too much space? Many people use the ubiquitous single driver on a narrow front baffle augmented by back-folded wings on piano hinges...I like those three mids; what are they doing -- canc...

Glad you came around to my way of thinking. Without actually hearing "X" it is kind of silly to have strong and well formed opinions about X's sound.If "Lowther" is used as a generic name for single driver speaker, then it is impossible to have a mea...
