All I can say is wow!
There have not been any user-noticable changes in the series over the years.
The drivers for the home products are the similar to the car products but different to match up with a 120V power amp assy.
None of these "matching" issues have anything to do with each other. Both I and "we" have set up an insane number of complex combinations, and in order of "what matters:" it's 70% room acoustics and sub placement, 25% timing issues, and 5% EVERYTHING ELSE.
Therefore I am going to start with my white papers . Since you are obviously a loyal JL customer (!) if you give me your snail mail address I will send you my test CD free of charge.
Please feel free to call me to discuss any of this.
It will of course be MOST helpful to know everything about your setup:
Home theater or 2-channel, etc preferences
Types of music, for example well-recorded jazz, classical, old rock, broadway, techno dub step, etc etc.
Here are the white papers and links I promised.
But first... a tiny shameless plug...
As per last week’s discussion regarding my experiences with your surround system calibration technique/subwoofer alignment:
“…The results of the Soundoctor sound system calibration technique are nothing short of transcendental.
In addition to jaw dropping improvements in sonic “punch” and visceral impact, phantom center coherency and soundstage imaging for frequencies well above the subwoofer crossover frequency are also vastly improved, even on “real-world” systems with non-optimal geometry or acoustic environments…
I’m now on a quest to re-calibrate every system I’ve ever installed using the Soundoctor method!”

Look for the SUBS paper: www.soundoctor.com/whitepapers/subs.htm
This is an in-depth discussion of every method of "adding a sub".
There's also my newest TEST CD , with the accompanying setup hints, here:
Here's a secret page (not linked on any menu, not indexed) which describes a professional mastering studio:
What this proves is just what a pair of correctly installed and set up 112's (not even 113's !!!) can do - it's astonishing. (hint: it's just about ALL room acoustics)
Since room acoustics is certainly some 70% of the battle, Art Noxon has some great acoustic articles:
If you're interested in MORE acoustics links, see here:
(I helped start the Boston Audio Society in 1971, before they invented water,
and have been the webmaster for 17 years)
Here's a page that discusses (AC) power requirements, real and imagined...
And last but hardly least, here's a teaser page showing the NEW crossover!
Just in !!! - a review of the e-subs.
Again, phone time is often the most productive, but email back your tech info.
