[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

[quote user="Edgar="]Not Amplitude. It's the rock solid phase linearity. It feels like a brick wall all the way up and down. I haven't looked at any graphs and haven't measured anything but that is my guess. There is no question of the great tone of ...

nope. i truly believe it to be one of the best and definitely without argument most innovative speaker designs ever made. sorry if you don't see that.you need to learn more about them tho, because you didn't even realize what drivers they used from t...

I have had similar impressions to other speakers using these drivers. For example I found the top of the line Avalon Eidolon diamond to be similarly colorless and lifeless. Also a pair of Vaic speakers (designed by the guy from Lumenwhite...

In our experiments, the more power we threw at the A7s, the better they worked. I heard some of the original "theater" version Altecs playing with their original "dedicated" Altec amps, and these sounded considerably better; but I never got ahol...

But why would you consider brass connectors because of 95% of boutique RCA if the idea is to wind up with the best signal path?Probably, you will not use continuous wire from the cartridge coil, and you will probably not solder but use some sort of c...

Romy, Our bass driver has a 12v field coil motor, it developes just over 20 kilogauss flux density using a low carbon steel pole piece. The exit diameter is 4 inches at the moment. The diaphragm is 6 inches in diameter and mad...

Romy,you did not disappoint my expectation in your reply. Who can argue with the take: "bugger off and do some home-work"? On the other hand, when looking through that "Knowledge tree TM" it's more of a "forest" as far as horns are concerned. So it's...
|
|
[quote user="JLH"] In addition, the idea of an ultimate horn profile does not make any sense. Each and every horn profile has its own strengths and weakness. Depending on your goals, and the drivers you have, one profile will be "bett...
|
|
It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. They already had splurged for...

hi Dominic i made myself the same question regarding the high frequencies in the orphean horn. the reason is probably because this horn has no compression, and the horn length is not so deep, and the exit diameter is 2 inch, quit big. If you read my ...
|
|
I completely agree with what you said. To tell you the truth I was already very satisfied with sound, but I just wanted to make that powerful triode amplifier - I really don't need it. But it's nice to have it. As you know in this hobby it's not so m...

|
Haralanov, I've spun this thread off the "Speakers for a Powerful SET" thread, as you suggested. I took a couple of pictures, but I can't figure out how to upload them, just yet. I'm also not sure what you could see from the outside, anyway.As for th...

This stuff has been stuck in my mind for some time now, working around in there against my ongoing experience, against what I am now running. The goal is a more dynamic presentation with better spectral balance, with the emphasis on LF and [more] cor...

|
Mani, I am not saying that any driver (let alone any collection of drivers...) will ever be entirely "correct" in terms of acoustical instrumental timbre, no matter the frequency range it attempts to address. I am saying that the sonic "weight balan...
|
|
I would have to believe there were big sonic gains in store before I went through the trouble of designing, building, testing, (and re-building) and integrating giant horns in any house. Romy, as I recall, you already have enough 15" drivers on hand...
|
|
I agree that the right 15" is a nice size for mid-upper bass. I suppose yours are the 15" Vitavoxes that were made to go in boxes? Of course, the usual reason for ports is to "extend" LF, and most modern LF drivers are used in something like this, ...
|
|
OK, I have one foot back in the water again, a hand-me-down monoblock from a "well-respected movie sound producer", to whom I am connected through dear friends. Like most "sound professionals", he is fairly dismissive of the way "we" hi-fi nerds go ...
|
|
Decoud, you will only know if you try it, but my long experience with the Lowther makes me doubt its suitability for your situation. Perhaps there are other, more suitable single drivers, I don't know. While I have no idea at all what you want to w...
|
|
Romy, it sounds like you are well into this, already. We used to use extremely sheer silk with our "secret" doping formulae. The key is to keep it as thin and flexible as possible. Today, I would look for resin/glue with "fibers" in it to bridge t...

Wojtek, I do use 8 Ohm drivers, and I am mildly curious about the "pattern" thing. As I said in posted responses to Bud, I +/- accept the science but suspect the implementation in this case; however, I would be happy to give a listen...
|
|
Three problems with the Scan-Speak are the low X-max, the built-in response curve, and limited power handling. It will be interesting to see how you juggle these issues if you do use these guys for LF. Obviously, if you bias against the natural ris...

HI "Hifiordie" I want to tell the readers here that this guy is seriuos and has some serious talent.Unluckily for him he has been bitten by the same insect that got us and is obsessed by horns, please do listen to Romy and try to balance your life b...

Hello guys! I got an old Coral X-VIII from Japan. Its an Onken enclosure with a 400 Hz horn. And I want to give it a second life. The enclosure looks already like new. And the question is about the crossover. What would be the theoretical best points...

|
Romy, the first time that I noticed that the speaker wires are very important to the sound was when Steve put some very expensive audiophile wires in place of our normal magnet wire. I walked into the room while familiar musi...

[quote user="drdna"]Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned. Looking at the phase of the individual drivers and listening to each of them individually revealed that ...

My a-musical woes, mentioned briefly above, were traced to the ML2s' fading drivers. This report is written after the 6N6Ps were repalced. As it turns out, the TAP did not figure into the problems, and minor system changes do not&nbs...

Greg, I have written about my "DEBZ" speakers several times at this site, including Post ID 3269, early in my original Lamm ML2 thread. I mention these speakers now to compare what we are aiming at here to what I have already done, wh...

Perhaps there are ways to horn load Lowthers that do not screw up the sound, but I don't know of any, and there are other reasons, as well, for not asking LF from Lowthers.For me the best thing about the high-pass-limited Lowther DX4 in OB is th...
