There is no way to be sure of which crossover design actually sounds better without listening to an A/B of with/without bypass. You just have to listen and decide what you like in your speaker, your room, with your crossover components.
2. Also, there is no way of knowing without trying it out what the interaction between a given capacitor and its bypass will be. Although, if the capacitor is not of very very high quality the odds improve that there will be sonic benefit to adding a bypass capacitor to the main capacitor.
3. JBL apparently thinks enough of bypass-enhanced design to continue doing it in their Pro line. In other words, even after the general quality of audio-purposed capacitors increased dramatically they continued to see the value of adding bypass capacitors to their networks.
Given the above, I'm gonna ask my guy to add the bypass caps back into the mix for my rebuilt L112's. I'll let you know how it turns out.
