I just remembered that I sometimes use a cementatious material that has added to it a fair amount of foam-ish beads and acrylic. The stuff sets up like cement but is MUCH lighter than cement or plaster, perhaps 2/3 lighter. I mention this...

[quote user="Paul S"]The things I like best about a good wide-range driver are coherence and immediacy: like nothing else I know of, but awareness of the limited range quickly come to the fore.[/quote]Paul, my experience with wide range drivers is li...

KOT, with the ML2s I found very little difference in the sound of various 6C33Cs, but the old Svetlanas certainly "held to spec" better (and longer..). I find the 6C33C to be more "direct" sounding than 845 or 211, but this in the context of a 3-sta...

I have also been working on a pair of Macondo-inspired horn-speakers. Horns from Stereo Lab, but with horn-drivers from JBL, rather than the elusive Vitavox. I hold Romy's forum in very high regard because of the content-standard of the posted messag...

[quote user="Marc HENRY"]hi all,thanks for your interest !yes the frame is curved, HF and MF are //yes there is a phase plug in the bass horn. This cover 80-300Hz.there is a separate infra-bass section, covering 20-80Hz.images of the bass phase p...

my vitavox S2's finally arrived today.i was not expecting great results with all the warnings i read on this site,especially with the klangy stock 4 cell 330hz vitavox horn.i know refinement when i hear it.i have heard avantgarde's duo, trio,i even h...

It's not the "technical" stuff that's being solicited here, rather it is your sonic objectives laid out in plain, simple terms. Looking at the "stuff" is not enough, especially if no one knows how it sounds to you, or how you want it to sound. What...

Gera, isn't the basic idea of the [front loaded] horn to provide shaped, increasing gain as the frequency drops? So, is the idea here to use several wide-range drivers that all need similar boost, or ???If to reverse engineer such a thing, what are ...

From the time of the insertion and setting the proper crossover my midbass is growing and growing, getting larger, deeper and better in all aspects. I am not kidding and now, when I have no ULF channels operational, it is very obvious. I can’t explai...

[quote user="jessie.dazzle"]In the few converstaions I've had with him, Mike seems totally sincere and, as I've mentioned before, I very much hope he will one day come through.jd*[/quote]Well Jessie, it looks like your wish has come true. The Vitavox...

I am out the door, just wanted to mention, it is my understanding that only one of these was meant for a horn; the other is a direct driver, like the original 515.I assume the celebrated "slotted" Vitavox horn is not the same as the one and only Vita...

Mats, I must have missed something. What do you see in the Audiotekne photo that you ask after the bass box? My usual ADHD glance only took in a double-wall-with-double-cutouts front baffle(s), and the (small-ish) size of it; maybe some sort of BR ...

One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tried them on the orig...
|
|
Jorge, from your posts, I gather that you actually listen to your results. So you realize there is no way to predict what Haralanov's driver would sound like in (your) horn... except...As Romy has said, "articulate", tone-rich direct, paper drivers...

Romy,Did you ever experiment with DML or BMR type drivers for ambience channels?https://www.tectonicaudiolabs.com/audio-components/bmr-speakers/https://uk.kef.com/products/t101-satellite-speakersThere is something quite wonderful about how they work ...
|

Well, I have just taken receipt of my Orelo speakers (pic attached) - the bigger version of the Orelino speakers, with 3x 15" bass drivers per channel as opposed to 3x 12" drivers.I realize that Romy doesn't regard the coaxial BMS mid/high compressio...

Well, the Q5s were everywhere when I was trying to find big amps, and they really have no chance to move me. Even to do what they might do would take maybe 500W SS, yet Harley thinks he hears them at their best with the ML2.2. Then again, I suppose...

Brian,Microphone diaphrams, headphone diaphrams ,dome tweeters, all have to have the pattern applied with a technical pen i.e. Kohinoor or Mars. These are becomming a little difficult to find in all towns. A 50% mixture of Poly S and water should be ...

wow.thanks for comments.La Grande Castine will not be as expensive as Cessaro Gamma.i am sorry but i cannot answer to all questions, for several reasons you can understand.we have tested many drivers since the early prototype of La Grande Castine. BM...

Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter how high you cross ov...
|
|
But doesn't putting the drivers on an inward-firing arc more or less shoot all the sound into a point, like the opposite of the Big Bang?This seems like an invitation to phase problems in the real world, and it also seems like it could bugg...

truth is i took a risk.i bought the s2s on ebay,and have never heard them.i was motivated to experiment and explore the core of the mac/melq system.i have owned many horns and heard many more. one case in point;avantgarde duo,i have heard this speake...

[quote user="drdna"] I think this 2A3 must have a specific set-up to sound its best. You have not found it yet. To begin with and familiarize yourself with the sound of it, I suggest sticking with the topology that has been tested by amplifier design...

BR, I have never used Romy's amp design, but I have used 6C33C SETs with Lowthers. I do not use my Lowthers FR, for reasons that are fully explicated throughout this site, so I don't worry about LF from those drivers. IMO, their best is MF up to tr...

Well, I didn't come so close to answer your question right.I saw a few from the German DIY scenery and for them it was like the return of Jesus, best sound on PlanetBut probably they are still deaf as usual, because the Frequency step ups are limited...

Romy, are these drivers going to wind up in the ceiling horns? I currently use 15" Audax PR380M2 paper drivers in conservatively-tuned BR bins, X/O'd 3rd order at ~ 125 Hz. I do this because I need the gain with my current amp set-up. These drivers ...

What kind of futzing would it take to work an attenuated T350 or something like that back in there, just to check it against massed strings and the other impossible-to-achieve standards that tell everything about the "mid HF" qualities?All that x...

I hear you, Romy, too many other things going on to do this full time, like "the old days". To save time and effort, you could try to "repeat" the original Dannoy configuration (same gear and location) and hear if it is "repeatable". If not, you're d...

One thing for certain, they will want serious money before they get into it with someone. And how many times "back and forth", tuning drivers to horns, each other, the amps, X/Os, and the room, does that include? I remember playing with other peop...
