Romy,
Put them in a box and send them to me. Did you notice the replacement diaphrams available on eBay? Gone now, but they did not sell so will probably return.Bud...

Romy,Just one last note here, since many folks will start here. Having finally finished reading your enourmous work on the Vitavox drivers I would NOT reccomend using this process on them. It would be so very difficult to arrive at the corr...

This thread is a derivation from the thread:
An ultimate transformer within a narrow bandwidth?
Since my Super Milquades is up and running I’m wondering what can I do with the output transformer at HF channel in order to push the envelop of “possi...

Bud, you sure make a case for your process, all right. And the problems I have noted grew through the hot afternoon, eg, the power was certainly AFU.Of course I am curious, and your very intelligent discourse about hypnotizes me.At this po...

I tried the driver and generally I do like it’s sound a lot. It more sophisticated then Linaeum, it is more noble tonally and alike the Linaeum is seamlessly melts with Vitavox S2. In fact I am developing recently a theorem according to which a compr...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

[quote user="Bud"]First thing I would try is a single dot of Elmer's White Glue applied in the exact center of the dome, on the outside. The dot would be the size of a round wooden toothpick, cut off at the beginning of the taper. Dipped in the glue,...

I understand what you are saying in conceptual level and I agree 99% of us are molded in the frame work of the industry, but in practice, don't we need "knowledge and experience" albeit from a different perspective (the listening awareness)? Th...

Hi Panos,Romy asked me for a sanity check on your stated performance limits for your SE OPT's. It is good to see someone paying some attention to what is in the Radiotron Designers Handbook for high performance coils. What you are doing, winding five...

Paul,They might. If they are radial rings, straight out from center to outer edge then no effect. If they are a spiral then maybe a small effect that will cause you to coat the cone in the Microscale product with 3 or 4 coats. For circumferentia...

|
Rich,I have been experimenting with true Litz magnet wire (we use it in our transformers occaisionally) and have discovered that you can use discreete amounts of plastic dielectric material, spaced down the length of the wire, to "tune" the dynamic c...
|
|
Antonio,Works just fine with ported, unported or open baffle. The process works on the boundary layer of the cone. This is the very thin area between cone material and air. The actual mechanism just disallows energy trapped in this zone from reflecti...

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...

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...

Good luck getting midrange from F120A for non annoying monitors. Seems reasonable to expect, many people have been very happy with these drivers... I haven't tried this specific driver, but have spent some time trying to get a simila...
|
|
KM, I don't know how you come up with the belief that I conclude that "it's a bad performing driver." Either the 138, or the earlier 120... Or that because I didn't use 120s that i haven't heard them. And as ever...

This is an exploratory tweak. You will be finding out if your system is amenable. Take a 2 foot long piece of lamp cord. Split it into two pieces. Strip the insulation off of both ends and make a loop out of the wire length by twisting the ends toget...

I have been poking around your highly intellectual site for a day or two now. Quite excellent. I noticed you have direct drive towers for bass fundiment support. Would you want to clarify their activity and bring it to the level of the horns? I have ...

The Big Secret of Cables is a fact, well know fact BTW, that electricity does not flow in cable but rather within an electromagnetic field around the conductor. The cable’s nearfield (let say 2” around a conductor) is as critical environment as the c...

My first choice would be a Sony SACD recorder with storage in SACD format. Quite expensive, but I would not use an expensive Sony playback device. Their early models (still available new on ebay) were designed to show how much better than regular CD ...

Romy,The only card that seems serious is the Creative Live Drive series. They have the capability of encoding at HDCD sample rates and also have a front panal input / output fascia with many conntrols and buttons to explore and screw up with. I have ...
|
|
CV,All that you point to is quite correct. My comments were based strictly upon which coil voltage would be a superior sounding electromagnet. The only benefit I can see to a higher voltage is the faster rise time in the voice coil of the induced EM...

[quote user="Romy the Cat"]Yes, they are Fane 24” bass driver with 24Hz primary resonance. I am waiting for the final sound check; the final is long time away. I will be testing today different back chamber size and different drivers. I have a few Al...
|
|
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...
|
|
Romy, Not sure I can add much more.... you'll find out yourself of course. Overall, I can not comment on the "enabl" treatment beyond what, Dave, Chris and Bud have said (Dave and Chris are the Planet10 guys). I think I would have tried th...

Romy, I picked up a pair of FX120 and F120A drivers over two years ago. I initially spent some time with the FX120 in a small 10-liter ported enclosure (similar to Fostex' recommended one but altered dimensions). After many months of liste...

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 ...

All transformers are phase inverting. The lowest leakage point of primary and secondary windings relationship to conventional E/I and C core is the physical start of the helical spiral winding. This is assuming more than one layer of wire. In toroid'...

I do not know Bud. I report only what I see and I believe in what I experience. Almond all SETs that I personally have heard the Lamm ML2.0 had the widest subjective frequency range. I did measured how ML2.0 clip and it was at 18Hz at the bottom and...

Hello chaps,
Another option thrown in there by Bud; always enjoy your posts even if I don't follow them 100%...Let me attempt to barbarically distil what you said into 2 aspects which are
1) The dielectric properties of the insulating materials2) M...
