Dear JBL lovers,
I would like to share with you my JBL4355 replica, from Italy!
first of all this is a really expensive project, and it's really difficult to find components in good condition...
I was coming from a Setup build up with JBL4560 with Altec 416-8A and 2441 in 2350 plus fostex Ft65h (i'm still owner of box and horn)
so...2441 was present...lets start.
I decided since beginning to avoid a FULL replica with Classic blue and classic walnut veneer, not because i don't like, but to avoid drastic mistakes and reduce a bit enclosure cost (i'm not expert in veneer and i've no skills to do it). A carpenteer friend of mine help me in the construction than i'm finishing in house the internal furniture.
we used 24mm birch (really heavy strong and dense) for full structure, at the end is something like double the weight and rigidity of a normal playwood (a 24mm thickness count something like 14-16 layers)
we decided for a removable back to help working inside, maybe later on, this back panel will be fixed and glued together with the box, let see how it sound...
I decided to try with a normal filtering without Charge coupled variant, but i will try also the equivalent schematic simulating the autotrasformer.
I Re-use some material coming from previous setup, so expense was not huge, and i'm also thinking to try a full passive variant.
for the moment I just found an UREI 5235 and I'm going to build 290hz 18db board for him.
I'll start with a couple of UCD400H&R for woofers and MC2120 alternate with Uesugi 211 tube amplifier for mid-high.
At the moment I miss 4-2235h, I found them in USA but I'm thinking about the huge expense to bring them to Italy (i just bought a mint 2202h couple from USA...sigh!) but I have 4 E140 basket empty and 4 2226h that i want to try (setting the tune to 35hz), simulation show not far away response, even if i suppose 2235 sound far much lower and better (maybe)...
so, come on and Kill me with suggestions/opinions!
