2225/2235h conversion question

[rlslavik]

Hey all,
I am presently attempting to recone a set of JBL 2225s to 2235hs and have bought an aftermarket, disassembled kit for the job. Not a great choice I fear, but the money is already spent...
The generic instructions say to "set the VC height" firmly against the shim prior to gluing - duh. But being generic instructions, nowhere does it say HOW to set the height, or at WHAT height.
I contacted the seller and was told the last coil on the VC should sit 1/4 inch above the magnet base.
But doing this puts the spyder effectively TOUCHING the top coil.
And every "assembled" recone kit I have seen shows a definate gap between the top coil and the spyder, I'm guessing 1/8th to 1/4 of an inch.
My new 2235h VC is taller and has more coils than the original 2225 that came out, as expected, so I believe it to be an accurate enough reproduction of the VC.
So, question to anyone who has done this or has originals to compare to -
what should the distance be from the nearest coil winding on the 2235h VC to the "glue line" or nearest edge of the spyder?
Or is it more important and correct to ask - what is the distance from the farthest (1st) coil winding to the spyder?

Does it really matter as it will never be accurate enough no matter what?

But you are right there is a space between the top winding on the coil and the spider glue point.

well, being that nothing is EVER perfect, why do we do anything at all?
But, I get your point. Just don't see the economics to a perfect pair of factory 2235hs.

As well as sound, the VC could hit the back if installed too deep.
Installed to shallow, the dust cap won't even fit.

Per my 1/4 inch instructions, the dust cap sits a good 3/8ths of an inch out of the cone. Looks high to me and how does the mass ring fit at that point?

But I would actually like it to be correct for the sound as well...

If there is an actual "measurement" for the height, like someone with one pulled apart at the moment, I'm simply looking for it.

Go back and ask the supplier of the kit that you have. It is difficult to judge what to do without seeing the parts. I am not sure that I would try a recone with an unassembled kit. I have done heaps of the others but do not think that I would try this. Too many things to go wrong.

yeah, I just sent them another Email stating to them the way I understand their instructions and the fact that there would be no gap between the VC and spyder.
Should get an answer later today.

Bought the kit a year+ back. Never even SAW an assembled kit at that time. Wish I had.

At this point the WORST I can do is assemble it all wrong and buy a couple assembled kits afterwards.

Glad I have at least as MUCH dollars as sense...

Not sure you can buy assembled kits for these. Unless you can get the genuine JBL kit if you are in the know.....
