So, what you would have to do is buy a bunch of #9 AWG solid copper wire from China, so it is only 99% pure,acid etch the surface, paint it with tar and wind it up in a snake sex twist. Or pay them to do it for you.The idea is sound, the application ...

Sounds to me like your switch mode transformer is doing the buzzing. I recently purchased an APC product that charged the battery constantly, so long as it was plugged in. This caused quite a bit of heat and stench, from the hot switch mode power sup...

Hi Paul,The net gauge for one cable of the 140 strands of #40 stuff is #15 AWG, as far as circular mils of area vs current induced heating goes. The surface area is some 13 times that of a solid #15 gauge copper wire. A minimum of 10 times the surfac...

Romy,Try wrapping a copper wire around a power cable, then "inject" it into the power line through an isolation transformer. The wrapping only to help defeat the antenna event of other signal sources that only have one vector.et all,For cables, the m...
|
|
Romy does explain things correctly, in his own way of course.Modern electrical field theory has it that the electrical field attached to a cable, stops progressing along the cable for every vector change in the field. Not exactly a digital event but ...

If you are brave and have a steady hand go here for a way to SOLVE Lowther problems. Without reconning. Ask Jon Ver Halen of Lowther America for his opinion too.http://www.diyaudio.com/forums/showthread.php?postid=1248682#post1248682 post 345http://...

Romy,All measured tests for unsmoothed frequency response actually show that the violent peaks and valleys in frequency response, that driver mfg's usually will not show you, are just accentuated by EnABL. A friend of mine, one Gary Pimm, pointed out...
|
|
Romy,In the diyaudio thread on EnABL I cover the Hemp acoustics FR 4.5 C and the Lowther A45. Both drivers in your size range.Since EnABL does not measurably alter any compression wave characterisitcs of the piaton mode tests, except for phase shift ...
|
|
Romy,We have discussed apottted Compression Driver's before, and I would not commit to promising performance you would like. Howere, here is a place where spotted speakers might well answer your needs, without altering anything you are currently doin...

Andy,These are sensationaly deep recordings, just as you said they would be. DYNAMICS from a distance, and no artificially sick or flat notes, or hidden masses of groaning monsters.Romy you need to help this man, put his recordings on your broadband ...

Yoshi,What material do you have as damping material in the box and how close is it to the Lowther? These things are incredibly transparent to what is behind them. Some things to consider.If the damping material is within 3 inches of the cone, it will...

For those of you who cringe at the thought of making a change in your costly drivers and not knowing if it has been a disaster until it is, or is not. Here is a post from an inventive lad who claims to live in an ivory tower, but has a practical answ...

Romy is being very kind to me and not shouting at me for wasting everyone's time.Paul, I really do not think that lipstick on a pig get's to the heart of the DX 4 transform. It's much more like a stick of dynamite hanging from the pigs lips and...
|
|
Paul,Actually they do not sound different. As shown in everyone's tests, those objective measures of performance do not change more than you might expect two different drivers of the same type, manufacturer and production run to sound. What changes a...

Paul,And any one else that is interested in what may be a new leaf in the Lowther book.Please go to the first post. This is from a participent in this forum. He may choose to speak up and he may not.http://www.diyaudio.com/forums/showthread.php?posti...

How about a motor generator? Both on the same shaft, and, you could even put a CVS constant voltage sine wave transformer in, to supply the electric motor part, to keep the speed constant. About 6 kVa should do it, for both channels. Fill u...

Romy and Paul,Many years ago, when I worked for Mille Nestorovik he used seperate mains and a sperate ground connection for the entire system. Before turning it on for a listening session, he would send me outside to "water" the ground, for a good ha...

Hi all.I am just supplying a couple of threads that are dealing with application and the theory behind the EnABL process I provide information on here last year. Romy, you should not go there, it will make you crazy and you will have to insult someon...

I wonder if you could hang a secondary driver in a dead box, without baffle, or perhaps more usefully, with a shaped baffle and use it to provide the "resonance" effect of many vibrating panals of tuned length and specificshaped radiating areas...

Hi James,Just so you know about these folks. go to this site and page down for a bit till you find the horn installation topic. http://www.royaldevice.com/custom3.htmRather interesting and might be all of the mistakes you can make in one place, ...

Jim,UL has applied a compatability test to insulation materials since 1976. This test places representative amounts of each material, found within a potential transformer coil, in a test tube. This tube is then evacuated and subjected to infrared hea...

The entire pattern shrinks and grows geometrically, based upon the physical length of the edge of diaphragm involved. Please understand, this is not just a theoretical idea, I do and have done this process on many different types and sizes of d...

Gentlemen,
I suppose it is time to defend my sterling reputation here. The EnABL process does in deed work across the full frequency band. Works on all driver types and permits the very qualities that Romy seems to appreciate in the treated Linneum ...
|
|
Romy,Now that you have removed the slope try out the treated tweeter I provided you with so long ago, the one that sounded exactly like the untreated EV's. We would all like to know how that matches with the S2, in an unlimited application..... might...

Romy,About 6 mo's ago I purchased a Teac X7R becuse the man who ran the head mfg facility in Japan is still making heads and has new pinch rollers for the machines too. This is the X7R,X10R and X100 and X2000 series. The R stands for auto reverse so ...

Romy,I have no direct knowledge about these products. I only have a brochure, given to me by an evil person... well maybe not evil, but he does try to get male children, who are friends of his male child, to play in "Garage Rock an Roll Bands" rather...

RomyPerhaps this link and the information trumpeted within will help on this project. Certainly the leader of this pack has solid credentials in HF switching power supplies, though this particular link is actually about roasting transistors in an Aud...

Romy,Take a look at the output from the HP amp with a scope to make certain you do not have a high frequency oscillation in the amp. Under headphones this would be very seriously reinforced. Then check to see if you have a very low frequency oscillat...
