Hi santashooter,

Where are 2308 lenses ???

Ivica

Good point Ivica - this afternoon i'll mount the Velcro for the lenses and they get on

I’m the only one that do not like the listening with lenses?

Well i can't say yet - i have only listened without, but i need them mounted anyway and then i'll see what I think

Here comes a few more pictures taken with a better camera:

The lenses definitely affect the character of sound on those horns, neither good nor bad - a trade-off. I generally prefer the Selenium 14-50 . . . but they aren't "perfect" either. It's all an approximation (as Greg Timbers stated some time ago) in any case. Good hobby!

Those are stunning! Congrats. Look every bit as good as factory, maybe better because they are new. Your progress reminds me to get back to the next steps on my project.

In any case,amazing wood work!!! Congrats!

Hi berga12,

If not speaking of personal favor, without 2308 Jbl horns such as 2307, 2311 and 2312 would have very narrow horizontal dispersion, and about +3 or +4 dB emphasis FR over about 3.5kHz. Than can be easily proved by measurements. So using standard Jbl networks such as 3143, 44/45 would need some corrections and tuning.

Regards
Ivica

Hi Ivica, I know,I was just speaking about personal taste, even if it’s not intended By JBL developers.

Hi all - I am vey happy with my result but there is a part missing:
from what i've gathered JBL enclosures were both oiled and waxed.
Mine are just oiled right now using the 3 parts linseed oil 1 part Gum turpentine mix, but what wax should i use as a finish?
I live in Denmark, so some brands might be hard to obtain - any suggestions are appreciated.

as you might have seen/quessed i am very strictly adhering to originality, so I would like to get as close as possible to what JBL used themselves.

So,... I thought you would have used "Scandanavian Teak Oil"??? Sorry, I couldn't resist that!!!

Wow! What a wonderful build! I am Soooo envious! I still haven't got boxes for all my drivers - although I AM listening to them...

I hope you're up to plenty of questions so far after your project.. They should have really started to settle in by now and 'really' sound nice!!!
