Yep, got that earlier today.

Good Info!!
Thanks for the overview!
:)
Yes, you're right about your concerns about the Voice-Coil depth ( vis-a-vis ) being properly centered to the middle of a JBL's top-plate ( iow, the gap-depth alignment ).
That may need adjusting...
Thanks for those times Rob ( I hadn't yet gotten to those points ).
:)
Hi,
I'm glad that you all mentioned the 120deg horizontal dispersion of GT's custom printed horn ( after seeing the pic of his current system I was left wondering...
FWIW, I think your cone kit is actually from a Stage Accompany 1503 woofer.
Not that it matters much, since it's obviously compatible with the JBL magnetic assembly ( which SA copied when they...
Hi Silvanik,
My advice ( if you want to go 100% active-DSP ) would be to contact Harman International > get a recommendation from them for a qualified Synthesis technician for your area and then...
@MoD
MoD, the 75 grams measured weight obtained from a scale doesn't represent a drivers MMS
What you obtained by weighing your recone kit on a kitchen scale is more accurately called the...
The following list ( first linked to by RobH in his above post ) appears as one of Giskard's creations ( he was so good at this sort of thing that I imagine that he knew this all from memory ).

Cool patallen,
Your mystery 2225 recone will remain a mystery ( though FWIW, that rust-colored banding or glueline on the back is much more typical of a very specific generation of the 2226HPL...
Ian,
Thanks for demonstrating your complete understanding of the terms "MMS, MMD & Air-Load".
( Now to put it to use ), it would be helpful if you could puzzle-out why ( or offer-up a plausible...
Ian you're using the terms MMD & MMS backwards ( MMS = MMD plus air-load ).
That's definitely not helpful to this thread.
Go look at one of my early links posted in this thread ( to the...
The weight of my ( oem 2235H kit's ) dust-cap is 3 grams and the mass ring is 32 grams.
The kit is from @ 2001.
:)
One needs to entertain the possibility that JBL's TS numbers for the 2225H have always been wrong ( within their official documentation ).
After-all, JBL's numbers have proven to be wrong...
Thanks for implementing my suggestion to make your posts more readable. :thmbsup:
Now to your first question:
With the static weight of your eBay cone kit being around 105 grams, the missing...
Thanks for that! Denny
:)
@patallen,
It's appreciated that you attempt proper punctuation ( by including commas, periods, etc. ) in your sentence structures .
( Capitals, at the beginning of each sentence would help...
Thanks a lot Rob!
:)
2-Part Epoxy seems a reasonable choice for a part that might impact the pole piece ( inadvertently, of course ).
:)
Thanks Rob!

Hi Rob,
If you still own it, could you please publish the static weight ( including dust-cap ) of your JBL 129H recone kit ( I'll assume that you have an applicable kitchen scale...

I missed your most recent post.
Yes, I think you're ready to glue-up ( assuming things are also jiving with the GordonW info that I linked you to ).
:)
PS: I also have here a...
Thoughts??
If one looks at my pic of the OEM kit ( posted above ) the "collar" of the spider is pointing towards the voice-coil >> suggesting that you may have your spider flipped upside-down
...
Thanks for that.
Those kits seem to be real close to OEM JBL then , a good thing.
I notice I had a senior moment and changed a 1.25" measurement into a 4.25" measurement.
I'm going to...
What's the length ( height ) of your kit's Kapton former ( that the Voice-Coil is wound onto ) ??
OEM JBL ( from around year 2000 ) was @ 1.25" ( with about 1/8" sticking above the glue-line >...
