2 legendary speakers right there. JBL,(Just Be Loud)

Well, then, I have some questions on your L-100s.
I reviewed a few different options for crossovers, all the way up to 3rd order designs but my first option is to give the original 1st order HP design a good long listen. Personally I think they sound great, as is with the new caps. I thoroughly tested the original l-pads and they were consistent an not scratchy at all so I kept them. With a 1 volt RMS input signal, the l-pads attenuate an 8 ohm dummy load from .2 volts to about 1 volt at full volume.
The grills that I have attenuate my signal (pink noise) by 6 dB so when I'm really focusing, I run them with grills off. I'm guessing the aftermarket build on these grills was more focused on aesthetics than acoustics.
Also, I normally run with the mid (Presence) and tweeter (Brightness) L-pads turned up to +3 dB. I cant really see it as much on an FFT but the difference is obvious when sitting in the middle of pink noise and adjusting them one at a time.
Also, Im running them with some acoustic foam in the port and I reinsulated with good acoustic egg-crate foam.
So, My questions:

• Are you running original crossovers or have you modified. If original, have you recapped?
• What grills are you running:
• Where do you run your Presence and Brightness L-pad settings.
• Are you running the original drivers or have you mixed and matched?
• How far apart are your serial numbers? (mine are 156162A, 156111A)

Please pardon all the questions but I broke the first rule on the rebuild, I didn't do pre build tests.
