I care less about Bret and his business, in fact I have no idea who is he. Since he use audio as business then what distinct him from any other audio whore. A purpose of any business is supply demands and capitalize on the frustrations, investin...

[quote user="Romy the Cat"]That sucks. I use to have a box of perhaps a dozen of YO186 but I did not see it for a while, pretty much from the time I moved to new house. I was listening today some of my “critical” reference stuff and concluded with ve...

[quote user="jessie.dazzle"] There may be better drivers out there, but with my level of experience, I doubt my abilities to recognize them. So though it may resemble laziness on my part (remember, this is the same person that will be constructing a ...

I chose the EdgarHorns for fairly simple reasons. I have listened to them and I loved the way they sound. They are not the perfect loudspeaker, but they make much truer music than what I have now. Also, the price I paid is less than...

I have posted about some of my recent experience with longer "naked" HF ribbons in Romy's "Water Drop" thread. Here are some observations that relate these drivers back to the ML2s, along with some other recent ML2 trivia.My speakers are listed...

Hi Romy,I've seen and heard many products in which an aspect of the design is interesting, even thought provoking but where that idea's implementation is poorly achieved. It doesn't mean that one can't learn anything from the product even if it's onl...

IMHO one of these drivers that make you listen to the music at first, but something isn't quite "right". Put it on a - big - open baffle and cut at 200 and use maybe up to 2500Hz. Problematic with female voices, like opera and so on. It distorts quit...

If LF are sealed, I would suspect that the strong SS/hybrid would be better able to keep the drivers "off the air cushion". When the drivers get to that point I hear something I would describe like this: Take your fingernail and...

I agree entirely with your sentiments regarding marketing bs and its new found application in the promotion of field coils. I do have a problem however with the notion that the reproduction of 'western' music requires different attributes than ...

I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the drivers "off the ...

The hardest part of making the cork gaskets would be making a decent template. After that, it's just rote labor.You might also want to mess with whatever you are using to fasten the drivers to the baffle. These fsteners should probably al...

[quote user="Romy the Cat"]I am not sure what drives you: a desire to but a speaker of a desire to initiate a new group buy for ScanSpeak drivers. Knowing you I am pretty sure that if I do not put a stupid smiley face in the end of the last sentance ...

Someone please jog my memory by naming some previous true Class A1 SE pentode amps, since I can't for the life of me recall any. This might actually work pretty well if targeted for LF! Adjustable "feedback" could help tons with Z matching, a very ...

Setting aside the small drivers for LF, while the rest of us have been all ga-ga about the vertical array, the pros have long since moved to the "horizotal array" for LF. Although I plan for several large drivers in large "modified IB" cabinets, I t...

[quote user="Romy the Cat"]Here is pretty much the idea that I had – a very tall line array with min footprint and with more of less corrected timing error by angling the front baffle. At the picture below the curvature of positioning of Macondo chan...

I have tried both simple, "FR" drivers and multi-ways, and I think you are on to something with the "simpler presentation". As a generic example, think of the "cult" "FR" drivers driven by cult SETs, playing cello music. I have gotten goosebumps from...

How does the SPL/dynamic range correlate to frequency? Most of the old 10" drivers can play louder if not pushed down too far. I think as the years passed, the Tannoy had like most similar drivers a sort of "sliding scale" dynamics, and they would pl...
|
|
Bill, I had an issue like you described with your right speaker that I FINALLY traced to a "cold" solder joint in an RCA plug, on the amp end of the right pre-to-amp IC. To my ears, the old paper drivers are very, very sensitive to their "surrounding...
|

Robin, I don't know why, but for no reason at all I was thinking the 1" polyester driver was a dome! Its being a compression driver likely means a 2" diaphragm, and it certainly opens the door for sub-2kHz performance. Actually, it's 8" drivers doing...

The thing about horns is, "developing" them consumes a lot in terms of time and materials, and they are expensive to materialize. SPL modeling programs can be great for getting in the ballpark, but YMMV when it comes to "level of demands" from a hi-f...

Since no driver is actually full range, driver selection is partly conditioned by how well it plays with the other drivers it will be used with, and - very certainly - the crossovers it will be used with, also baffle shape(s) and size(s), amps(s), an...

Anthony, I agree with your central observation, and I have used paralleled HF drivers for decades, starting with the old Peerless paper tweeters paired with RTR6 electrostatic arrays, and now paper whizzers with Audaphon ribbons. As you know, this ca...

engineers have to offer, you need better engineers. Bruce Edgar did far better
by himself without those engineers. [/quote] Rowuk, you raised two subjects that in my view worth to

Romy, Radian 475be performs best over 2K. It has some distortion around 1700 Hz. I think in general that 1 inch drivers should not be used lower than 2K.I understand your point that the practical implementation is more important than a "best practice...

Romy, if you have some spare diaphragm/VC assemblies for your S2 drivers, do the experiment I mentioned above (remove the outer layer of the VC) and we will talk about the inductance in terms of sound after you hear the results with your own ears... ...

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear...

Haralanov, let me know if you actually have something, otherwise I will continue with the Audaphon ribbon for the first round of the downward-pitching exercise. On the one hand, I wish I'd kept the Peerless 2" paper tweeters I had; on the other hand,...

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...
