I don't have to "admit" anything because I didn't say anything wrong. I see my technical claims still remain unopposed. You only think I said something wrong because you don't understand what I wrote in the first place.

No, because what I wrote is right and what you wrote is wrong, and even you knew it was wrong right away.

You should have deleted it and saved everybody a lot of time. Why would the guy that is writing equations about tension vs force not realize that a film under tension takes more force to deflect?

Most "normal" people would think that too. IMO I am disappointed that so much of "hi-fi" is still trying to do everything electromechanically. We have good digital technology now. A system like jonfo's with woofer tower (multiple drivers with low displacement for low distortion), active...

Russ is retired and doesn't have to work if the doesn't want to and also very busy with other people's panel and will get around to yours when he feels like it.

In theory, the ML active woofer can have an active xo for better cutoff slope or time delay tweaks.

computer -> toslink spdif -> digital XO -> multiple coax spdif -> multiple DACs

Maybe the problem is that the effects are below the residential noise threshold as RUR mentioned. What you can try is to use Resonance Enhancers. They are also wood objects, sort of like a cylinder with one end capped, and outwards tapered walls. It's shaped sort of like a disposable paper...

You will have to list them again because in one of your posts you disavowed half of it.

yes I did.

This is like the lawyer in you speaking, right? Skip over the main point and try to get me on a technicality. Or maybe it is like when they try to attribute motivations and paint images? So anyway, I never said that horizontal tension was not "applied". I said that there is none in the...

a) the higher diaphragm tension means that it is harder to deflect out of plane. So more voltage is needed to make it move the same amount. Beyond that, I don't know specifically the relations between those things you mentioned, so you will have to look elsewhere for your answer. b) It's not...

Then don't go that high :) Then don't go that high :) Edit: Hmm, this give me a new idea. Maybe the spar spacing sets an upper limit on the vertical tension too.

In short, you want enough tension so that the resonant freq is much below the crossover point. There is nothing really wrong with higher tension since you could just increase the voltage to get a more powerful drive. People who build their own panels try to get as much tension as they can...

It's ok to not care, but I invite you to try one thing: Take an insulated stick (like the extension nozzle of a duster can) and lightly tap at your diaphragm in the middle. You will see just how little tension you have.

Oh good, another reasonable reply. How did you come up with the factor of two? I came up with around 12 or so.* *Note that I asked a question regarding somebody's supposition without questioning their motives or making commentary on their personality. A shining example of civil discourse, LOL.

yes If I assume the film has no shear-type deflections (not true), then there still would be a little tension at equilibrium. In practice, it would depend on the elastic properties of the mylar. For hypothetical example, you could lean really hard on the tension rig, and tug on the mylar in...

Ah, I realized something this morning. The reason there is very little horiz tension in the film is because mylar is relatively inelastic (more like PAPER than Saran wrap), so what happens when you put it on the tension rig, is that all the horiz tension / force goes into squeezing the spars...

Here goes: This is a free body force diagram on any particular chunk of mylar: Thin films can only exert forces in the plane and not perpendicular to it. The two horizontal tension forces sum into a net force that pulls the chunk down into the rear stator. Nothing opposes this force, which...

This thread is for discussion regarding my "controversial" statement that the ML curved panels don't have much horizontal tension in the diaphragm. Maybe after the moderators move some posts over, I will add more explanation and reply to certain points.
