So, I performed A first shot of measures but It seems that the cone itself was too "cold" (in the garage at -4°) so spider and suspension were still not at RT 20° so I got slightly different...

In the meantime that I'm performing few hours of suspension brake-up before measuring T&S parameters, what's looks strange ore unexpected for you? I compared my re-foam and suspension with many...

I'll perform measurement and post them

I don't know if this was coming from an old refoaming or this one, but for sure I was not able to do something better.... so bere we are,I can't complain so much...

I'm always working slow....due to missing time...

Port are done, reinforced with fiberglass (2 layer) in the conjunction and just Resin around.

The fitting on the box is not like I was...

maybe 4343 or 4333 :p

And finally,after 10 months.........thanks to many person of the forum (one in particular), I find out 6 JBL2235h, now time to select 4 of them, and Refoam, still have to decide if it's better to...

Dn92 that looks great!

yes I Would like to build new pcb and try different components with better precision(0,5-1%)

I can manage a bit French Thanks!
I will be contacting you by private...

If I remember Well was For cieling mount using chains

12W tube amp (211 tube,uesugi project) on mid high and Hypex UCD400HR on Low bass is something superb :bouncy: more than enough power need to drive those monsters in home application.

Everything is working! Incredible how natural the sound is, so dynamic and precise, warm and realistic!!!

I was not expecting that from the Crossover JBL5235, I was thinking it's just a piece of...

Today I will try my cardboard on my 5235, I received some Allen bradley Carbon resistance and Holco too, capacitors are Sprague Orange MKP and Wima one.

I find out only HI-Voltage components and...

If someone has the same issue than me, having a JBL 5235 with a 18db card with Eq for high freq...

here the modification that you have to do to bring this card with Eq into a normal 18db without...

I find out something that could fit...:D

I understand, mine have the interior Milled Like in the project drawing, so my front panel is Milled to have the Gap between inner and Outher diameter (I've 1/2" insertion in the front panel, or 12mm...

Yes...way to expensive....

I've to find out a 140mm Outer diameter (I've pre milled front....)

PVC is 140mm outher and 136,6mm inside like project.


it's 5-3/8" not 5" :)

Let me search...

Ok, I will search fror them in Italy, I also don't like PVC tubes, especially for this kind of angular needs...

Mine are Just pressed on the front of the box, so I can easily change with Longer...

If the woofer can go so low is better yes, if not is just causing problem, fine for 2235h.


Not difficult? :crying: I'm not a master in cutting tubes, and I found only plastic ones not carton.......

12" lenght for 2235? 30cm! Oh God! from the simulation is 240mm (c.a 9,8")

Now I've 85mm that's good to tune 2 2226h to 35hz (not 27-28hz like expected from a 2235).


I will make a Real...

And finally assembled! Now I've to switch them On!

in the meantime I'm preparing 2235h woofer, but final simulation shorws not that less with 2226, for sure faster and with more punch, but less...

This toroidal jantzen was at home already.

my plan is to change with an air core flat wire in the near future, but for a 2.4mH is quite expensive.


I have some 3.3mH L200 mundorf at home in...

Sorry, but I don't Agree, Solen are fine, but those are Mundorf (one Jantzen) and some Russian Cap, Far away better than Solen.

Just look their website and variety of product and price they have....

My crossover is also finish, I need to cut a nice Plexyglass Panel

I left space for eventual:

- Auto transformer for 2441
- Passive high pass for 2202h
- Passive low pass for Woofers
- space...

Ciao,
I didn't found the right "rubber cork" to my need at the shop, and the only Cork I found was really instable and fragile.

For the time being I used a 1cm x 3mm Neoprene that gave me a...

Mid high complete, and done some cabling on crossover network.....road to the "end"

Velcro is 3M type, so sticky that I don't need to put staplets! a bit wider than the original progect, this is...
