[quote user="AOK_Farmer"] Here's what I've been trying. 8 ohm 4.5 inch full range Omega driver in a 0.35 cu ft sealed box and 6 mH coil 200 Hz electrical crossover. The main speaker is JBL Array 1000. This full range driver has my favorite *tone* of ...

I would like to point out something that is going on here that I found truly remarkable.
For advanced people ho play with horns there is no second opinion that the vertical array, the Macondo/Cressaro-Gamma type of architecture, is THE ONLY one tha...

Chris, I did ask myself the same question: perhaps my given PTR9 is demagnetized. I called the last night to the owner of the tweeters and he said that he uses them for 7 years and they driver should be fine. He also expressed a lot of doubts if the ...

[quote user="noviygera"]
For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

It was very interesting experience today. My son have a birthday party and they decided to do it in our house. I was obliged to play Harry Potter in a big screen for 15 kids, so it's naturally make me too move all the speaker along the wall...

Yes, you are absolutely right.
If I make a much deeper cabinet and put many more drivers closer to each other
then I will have much more sensitive array. I do have 18 more of those drivers
and the idea did hit my mind. From what I have now an extr...

This weekend I was walking in my new listening room and did
some thinking how to organize everything. Unquestionably my first step would be
convers Milq LF section (bass line-array) from Midas accommodation to drive my woofer
tower, in a way how I...

I do not know, Antonio. The Beethoven’s symphonies are divert it would be difficult to point out a specific performance but rather an array performances:
3 - Toscanini, Schmidt-Isserstedt, Weingartner5 - Carlos Kleiber6 - Walter, Erich Kleiber, Boeh...

Well, I still do not know what the tweeter solution would be. I know exactly what I want to get: to soften the S2 driver and get HF extension but without introducing HF noise. I know exactly how it should sound I juts do not know at this point how it...

[quote user="Romy the Cat"] I have a feeling that if I have extra 6dB of gain and 4 times more power then I might be able to deal with new room. Sure, the only measurement in location would show. What I know is that I VERY much willing to preserve my...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

I have tried both SS and tubed PP with HF ribbons, but not until ML2s have I gotten the "calm HF" I wanted from the ribbons. I am still experimenting with the Audaphons, but they seem to do best from 4 Ohm tap. My little 2A3 SETs did...

I spent today couple hours to walk around my fist mouth. It is juts test-jointed with screws, not glue yet and it responses horribly to knocking. We put a few 2x4 brasses and frames. It looks like it will be 8” between the 2x4 and it will become some...

Sweat I did, but put on my very best poker face which, funnily enough, I find much easier to maintain whilst playing poker than I did when confronted by this array of spectacular wines. It wasn't the monetary value either; one simply cannot get most ...

[quote user="oxric"]Hi Anthony,I am amazed by the work you have accomplished so far and love your stands and horns stacks.Two comments though in term of overall esthetics although I realise that having spent so much time on this it may be too late to...

[quote user="el`Ol"]I think they could could make the sound more pleasant with an overkill of second harmonic distortion. But for people who prefer that kind of sound a relax-horn like Anima would be better anyway. No real solution. Maybe they should...

[quote user="KOTriode"]Ok, I just read your "Melquides Remote biasing". This technic can not be duplicate in my amp due to DC coupling, the C3G (I dont use 6E5P) driver stage basically adjust the 6C33C current in the output stage. Just for curiosity,...

Had some fun experimenting with 6e5p driver stage.playing with difrent output transformrs and resistors found that the stage can drive a speaker with ground connected to air. mabye this is widley know i did not know. + of speaker connected to bad ou...

Yes, both ends of the spectrum are tough to integrate with a quality MF.Of course, electrostats have no "push", but they seem to do all right (understatement) just supplementing way up there, in an array.The thing is, the "big" ribbons and 'stat...

I think what actually happens it that the dielectric, when it gets most fully discharged, simply takes some time again to get 'FULLY' recharged. The perode inbetween will make the loss angle (or power factor) become a lot worse. This means the caps' ...

Hi Romy,
I've met musicians who understand music to a far greater degree than (I suspect) you or I ever would. I wouldn't however necessarily trust their judgement on matters relating to good playback. Some of them use quite appalling systems and ye...

[quote user="amdismal"]The crossovers were fourth order, which is what I use on my horns. Second order, I have found, can give a better blending, but reduced the delicacy and transparency in my system. But it's very complicated, and further exacerb...

Your point about relative levels is well taken. Still, the typical concert grand piano, for instance, does about a 27 Hz fundamental, as I recall (and certain pianos go rather lower), and some other instruments are not far behind. If to simply low p...

[quote user="Jorge"]Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

[quote user="kodomo"]I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's h...

[quote user="kodomo"]I don't think you can align the tapped horn. My tapped horn has a total length around 5 metres. To time align that with my other drivers, its got to be around 5 metres closer than others. The only other solution is delaying the r...

Paul, in my view the air-caps as an ultimate cap, the ultimate by own intrinsic topology. It is particularly the case for the 834P- like application as in there the cap is not biased by high voltage DC and gets constantly re-polarized. You see the pr...
