No. It's total bullshit. I've built dozens of these nonsensical networks for various JBL loudspeaker systems and the only differences have been increased cost, complexity and physical size.
JBL came up with this little ploy to help sell their "top of the line" <snicker>, "state of the art" <who's art is the real question> loudspeaker systems.
Seriously, who doubles capacitance and then hooks it all up to a battery?
Capacitors suck so let's put twice as many of them in and make them twice as big, two wrongs make a right right?
A link to the system that started all this idiocy:

JBL has a very long history of propaganda... take the L300 for example. Have you ever read all the horseshit JBL printed about that hiss and boom box? Nelson Pass lost the last shred of respect I had for him when he wasted his time trying to make that system sound good using a different filter design.
Talk about throwing good money after bad!
How about we all stop this madness and drop this inane subject once and for all eh?
