you didn't ask the right people
That's pretty dismissive of the advice that was given in the previous thread. Maybe you can elaborate on exactly what you disagree with in regards to the recommendations that were given.
Like putting lipstick on a pig. No amount of crossover modifications are going to turn bad drivers into good drivers.
LE25-4 tweeters
LE5-6 mids
125A cast frame woofers
going to be hard to improve upon those drivers
The LE25-4 tweeter is an obsolete paper-cone tweeter that rolls off far too quickly. JBL themselves almost completely abandoned paper-cone tweeters within only a few years after the L36 was released.
The 125A woofer is mediocre at best. It's power-handling is pathetic, and if you try to push it too hard anyway, you'll just end up demagnetizing the tiny Alnico magnet that it uses. JBL switched to using Ferrite magnets soon afterward, which have higher power handling and do not suffer from potential demagnetization when exposed to large power spikes.
You seem to have a pretty high opinion of those drivers. I'd love for you to describe further what it is about them that you feel is worthy of such praise. I'm certainly open to other opinions.
Personally, I think the only "good" drivers in the L36 are the LE5-6 mids. They are acoustically equivalent to, and interchangeable with, most of the other even-numbered LE5 mids such as the LE5-8, LE5-10, and LE5-12. My L150 speakers, for example, use LE5-10 mids and they do their job admirably. That said, the LE5 series
does suffer from a rising response (output increases as frequency rises), which was fixed in the 104H series that followed. Either way, it takes more than just good midrange drivers to make a good speaker.
With that said, if the OP is content with the mediocre tweeters, the mediocre woofers could be augmented to an extent via the use of a subwoofer.
Help me turn these great looking speakers into great sound speakers ???
I would echo what hjames said. While it might sound good in theory, trying to "improve" the L36 by turning them into a pair of hodge-podge frankenstein speakers is only going to ruin the one thing they still have going for them - their resale value. Restore them and be content with their mediocrity for the sake of nostalgia, or sell them and get something better. Otherwise you're just putting a fart-pipe and fancy rims on a Honda Accord.
