good morning friends,
somehow i was fascinated about vintage jbl sound, the punchy bass and the clear highs and i like the sound. i had jbl l 100t3 and i love its sound from top to bottom.
i read a lot of great reviews about the Iconic JBL L 300 sound in lancing forum and other forums.
i decided to build the jbl l 300 clone with nelson pass crossover.first sourcing of all the components.
i have to buy the components with original diaphragms and original cones inorder to avoid any further problems.
it took me about 04 months to buy all the components and all are shipped to my location with some help from some members and friends.
all are purchased from ebay usa.
the crossover componets are purchased from madisound usa.
the potentiometers are taken from my old yamaha ns1000m crossover.
these are very high quality pots,hence taken for this project.

the components are
)jbl2405H(Slot tweeter for highs,equavalent to domestic 077)
2)jbl 2420 with 2412 long horn(equavalent to le85)
3)jbl 2235h for lows
4)all the crossover components are as per nelson pass and purchased from madisound
5)i didnt found smoked glass tops, hence normal 6mm black glass was used
6)3mm padding under the glass was sourced from market which had 1mm rubber sheet with 2mm felt/foam
7)all the insulation material is 2mm thick glass wool.
8)2way binding posts purchsed from ebay
9)jbl stickers are purchased from ebay(italian seller)
for painting i used one coat of wood primer and then used the automotive paint by spray.
i didnt done veneering till now but used some vinyl laminate for temperarily purpose.
grill are ready but still not decided whether to used magnetic grill guides or normal guides, once decided then i can go ahead with fixing of the cloth on the frame and drill the holes for grill.
i have to say lot of thanks for lancing forum which is having great resources for building of my project.
finally the sound,


its one of the best till date in my life...........

a little update

i updated the crossover from nelson pass to giskard....just to check which suites for my requirement.
i found giskard crossover is best suited for my requirement.
the warm ness is more and the attack is much improved.
finally i settle with giskard crossover.

Very Nice. I'm sure you're going to enjoy your L-300's just as much as I enjoy mine

Beautiful, beautiful job on those L300s, my friend! I'll bet you are very proud of them, aren't you? Thanks so much for posting photos of your work. Wish my work looked that pretty!

Excellent craftsmanship! One has to understand just how laborious a task building something like this is. Not just anyone can do this type work. I also have a pair of L-300's in my collection. No food in the fridge, but JBL and vintage audio gear all over the place...

[Ed Kreamer]

As beautiful as your boxes are the crossovers are even more so. Too bad that they won't be seen.
Superb!

Why did you use 4333 foilcals on an L300 clone? Nice work.

[Joseph Smith Jr]

kdlsrinu, what you mind actually posting a photo or two of your L300 project here for all to see rather than a link to an image host and sharing service?

Thank you

Joe

I agree with Ed—your crossovers are works of art. If I had built them I'd house them in vented Plexiglas boxes outside of the speaker cabinets to show them off.
