Has anybody ever seen the tinsel leads glued to the spyder
and if so why?

This is a brand new EAW speaker.

The voice coil leads are not penetrating the cone, as is more typical.

Somebody asked the question, "Why do we bring them out onto the cone and THEN poke them through?"

Anyway, to answer the question directly, no - I have never seen that, but neither have I before seen an EAW driver, nekked.

I must say, I do not like the tension that lead has - it is not loose, and appears to be pulling at the surround. Not good I would think.

Bugger! :blink: That doesn’t look right the spider is, well yes in sticky position! Try using a (surgical knife) and cut at it with little strokes you know like (Clint Eastwood in Escape from Alcatraz) :D don’t hack at it, little by little and hopefully you’ll be able to free the spider to move freely.:)

Notice that it's glued to the spider landing where there is no flex or tensioning.

There is a loop from there to the cone/coil apex.

In other words...

It's fine for that driver....it's designed that way.

Whoa are you saying that is intentional in the design, I’ve never seen a spider designed in that fashion before, never.

That certainly looks like a manufacturing flaw that got by the inspectors to me. There's no flex in the wire which will lead to premature failure, IMHO.

If it were 10PM on a Saturday night and I was the roadie for the PA system that had just failed, I'd be in there getting that dollop of glue - that clearly doesn't look like it should be there - out of the way and make sure the wire is flexible again.

The next business day, I'd be on the phone to the manufacturer, too.

Cheers,

Here...let me quote someone who does this kind of thing for a living....not just on JBL speakers.

Look at the photo...again. Look at the dollop of glue and where it is. It's anchored to the spider where it doesn't flex. Then there is a loop of tinsel lead over the spider where it does flex. That spider only has 3 pleats...not alot of area to cover. More tinsel lead flailing around doesn't automatically mean better. More just means more of an opportunity for fulcrum action to shake and break the lead wire and more of a chance for the lead to slap the cone and/or short out on the frame. Where it goes from the solder terminal to the spider....there is no flex....it doesn't move, which is good. To prove my theory, or prove me wrong...put the driver on a sweep generator and observe what is really happening there and leave the conjecture out of it.

Just enough in a linear motion is the right way.

Y'all have a Grand New Year.:)

[mikebake]

I believe you are correct.

[Mr. Widget]

I believe you are correct.I'm sure he is...:rotfl:


Widget

[johnaec]

I'm assuming both leads are glued the same way? Are other new EAW's the same?

[pelly3s]

that is the way rcf builds their speakers, the should be a staple under the glue too. 18 sound does the same thing, as do numerous other manufactures. it seems to be a euro thing with speakers. edge is completely correct with his response.

[scott fitlin]

I'm sure he is...:rotfl:


WidgetHe is? You dont say!

Oh, yeah, thats Bo Putnam, I almost forgot. :D

[mikebake]

I seemed to recall seeing one like that on another driver; maybe Turbosound.
