JBL L100, Re-creation

[cool9]

This is some incredible project that Troels Gravesen (Danish biochemist and Audio enthusiast) tackled. He designed and built proper cabinets (quite large) for the L100 system after an exhaustive analysis of the L100 drivers and original cabinets. It's truly great craftsmanship and engineering.

That's a beautiful build and he has awesome skills, but I have to wonder why anyone would go through all that and not just plan to use better drivers?

I don't know about the L100 drivers. But, the drivers in 4312A, appear to be very good - esp., the woofer and the tweeter.

I am just wondering if I can use the same DIY cabinet for my 4312A's drivers. (4312A model uses differnet derivers than L100/4311.)

Because he had them, and wanted to build different speakers with them. Crossover sales was a likely factor, as well. They are not cheap.

There's renewed interest in 123A(-x)/2213(H) of late, it being recognized as a uniquely competent driver, for the reasons he mentions. Would I build using the L100 mid and tweet? Probably not.

eWavers might take a look at his lowpass filter, maybe. No, I haven't tried it....

Ok. Sacrificing efficiency for the sake of musicality. Feasible.
Especially when you have a pair of 96 dB-efficient speakers.
