A Study of DMLs as a Full Range Speaker

Pointless in that your videos of carpet with some sound in the background for sure doesn't help anyone to build a better panel. Who cares what you come up with if you're not willing to share your findings. How the hell do we even know that's not some box speakers playing. So again mate, who cares?

Maybe you could start your own thread and call it "Carpet Music: The Ultra Secret Magic Mystery Panels...Don't Ask".

Its not pointless its letting you hear sort of how my panels sound like so others can compare them to there own. You mean like Spedges many sound clips? How do we know its not some box speakers playing m8?

So what makes you assume I am playing a box speaker and not a DML panel?

Let's see, hmmmmm, how many photos of actual panels and domes and ........ has Steve uploaded? I'll have to break out the calculator for this!

And yes it is pointless unless you share how you achieved it, it just boggles the mind that you can't understand this simple thing.

Its not pointless, how do you know when one says there panels sound good without playing a sound clip, do we just take there word for it? LOL Again why do you assume I am using box speakers instead of a DML panel?

Eveyone should post sound clips so we can compare how they sound like and if one likes the sound quality, if not you are holding back information isnt it all about sharing. LOL

And here we go..... It's the sharing part that you are ignoring or more so that you are avoiding. You're on the wrong thread to be holding back your build.

I never said I assume you are using box speakers, I'm just saying you could be using any type of speaker without proof of a true DML that you refuse to disclose

This is the last response I'll ever have to you, not worth my time.

Where are we going? lol Where is your video sound clip to share? See you get to pick and choose what you want to share right?

Could be= assuming. Why would you even fathom that though in the first place?

People now days are so entitled. lol

Also I am not sure what all the obsession is about my carpet? Yawl act as if you never seen a carpet before? lol

My objective from the start was to take sound clips not a video. The mic on my cellphone is on the top edge and to get the best sound quality the mic has to be facing directly at the panels hence why the lens is facing the carpet.

These DML panels are not magic carpet rides. lol

Ok folks nothing to see here carry on ol chaps back to your definition discussions of sound waves.

OK, enough of beating a dead horse, back on topic.

Just curious if anyone has used the DAEX32Q-8 to any good result. I revisited mine over the last couple of days and experimented on a glass panel, XPS, EPS, poly foam, and some hybrid thin ply/poly foam that sound really good with my 25FHE's.

It seems that the rubber boot on these are killing any sort of liveliness. They are as dull as repeating yourself and arguing with a box of rocks. I feel it's the boot because I unscrewed and bent those top springs back out of the way and re screwed using only the lower springs, but that's not all, I also mounted the exciter directly to the known nice ply/poly panels without using the screw in plastic "quick change plug". You get a full circle of direct as possible contact this way.

The result was the same dull output. I feel that was $40 down the drain and my only recourse is to cut off that boot and see if they are salvageable. Returning them is not an option. I'm just curious if that boot is holding back some nasty noise from the coil area as I don't see the purpose in it if not. (Waterproofing?) The springs are what keeps the coil aligned.

Open for suggestions as always, thanks.

Off topic again: I saw a Puma in our arroyo that could have been the twin of the one in the photo on my walk with the dog yesterday. 60 feet in front of us, thought it was a large bobcat until I brought up my binoculars and my jaw hit the sand. Got a good five seconds of viewing as it slowly trotted away.

I have tried them before and they were one of the worst if not the worst sounding exciters I've heard which is why I dont reccommend that exciter. You can get better sound from the DAEX25 for $22.49 a pair.

If you can remove the front black part off without breaking the voice coil then it should work better.

Anything that hinders the voice coil or the panel material from vibrating freely is not a good thing. For example any exciters with these so called "Legs" should be cut off as the legs hinders the vibrations of the panel. Anything that hinders the voice coil like the DAEX32Q and DAEX32SQ or TAEX32C20
 
And, that you have to be in that medium to hear the sound. And, that sound is an energy, not a thing. And that, air is the medium we live in. Air is not just around us, but also in us. You can be in front of the speaker, behind the speaker, above the speaker, below the speaker, in line with speaker, anywhere in the sphere, you still hear the sound. And, all you see is a to and fro motion of the speaker's membrane, DML or otherwise.
Ok, I can agree with that. You hear sound or other waves in a solid by virtue of the fact that it creates a similar sound in air under the righ circumstances. Or by eg listening via bone conduction. But do please try get to the crux of the matter before the new year. It’s like reading Dickens by instalments.
 
Toddincabo,
Hey, now! It's Christmas! If you don't like his videos, don't watch them, but bad-mouthing him is not in the spirit of this forum, or am I missing something here?
I think the sensitivity is not about the videos per se but the attitude. One every forum their seems to be at least one character whose every post is some variant of “I am the possessor of advanced techniques of which you dull fellows can only dream” “I’m not going to share them mind you, my purpose here is merely to gloat.”

I don’t know if mr AudioFrenzy is that guy, but Steve and Todd seem to think so.

In these modern days, you just don't read Dickens anymore!
The thing is, has anyone ever made a flat panel DML here without distortions? Or, is it still a guessing game?
 
Not complaining at all. I quite like those usages in fact. I was explaining to Christian their meaning, their tone and the way they are understood by English speakers.
+ @Audiofrenzy
It was also my understanding and I appreciate to have some explanation of wording I don't know or when there is no help from translators. All the readers are not English native.

Yes, the legs have to cut off, as they add distortion. Also, anything other than the voice coil bobbin and suspension, if there's one. Even the little magnet hinders, so it has to be fixed a support, and that support shouldn't touch the panel, that is, if you are using a flat panel. The panel itself becomes a weight for the voice coil bobbin and that too hinders the sound propagating activity. The problem is how to touch the flat panel (in this case) without adding extra weight to the bobbin, pulling it down, distorting its to and fro movement. Then comes the question how to support the panel, so it won't pass its weight to the voice coil bobbin. Should it be fixed hard or soft? Whether the support is hard or soft, the frame also becomes a part of the panel, which in turn adds distortion.

Have we found a solution for this?

Who's we? lol Yes we have and its been around forever. Its called a Loudspeaker DRIVER. Or in DML terms its a BMR driver or Sony likes to call them APM, others like techniques call it flat honeycomb? Yamaha has done it , Bertagni has done it. etc etc.

The Basket (aka. Frame)– the physical structure that holds the entire driver together holding the magnet in place like a brace/spine.

The Suspension (surround) usually made of cloth, foam or butyl rubber holds the diaphragms weight in place.
 
Toddincabo,
I agree with your assessment. I remember him from 2 other forums, and he was pretty hard to live with on them, too. He keeps changing his name to throw us off the scent. I was starting to get the whiff of him, and I guess you just sniffed him out sooner. No hard feelings, eh? My intent was only to try to keep the peace. Merry Christmas!
