Preliminary Listening Impressions:
I've listened to these off and on for two days now. I call them "Mini-Everests" when I have the LE14H-3 woofers angled in the requisite 30°, and "Z3100's" when they're flush. ;)
It's disconcerting at first: we're used to being able to locate and adjust the image with minor changes in our position relative to the two speakers. Once properly set up, no matter with these. The only way to move the image (which is as expansive as the separation,) is by changing the relative loudness of the left vs. right channels. Otherwise, it just stays put, rock solid.
If you move in line with one or the other of the speakers, or even slightly beyond, the image stays centered between them. You can turn your back on them and it's still there, same place, same size. :p
It's a new listening experience for me, and it took some getting used to. Once I acknowledged what was going on in my head and gave in to it, it became most pleasurable, and there may be no going back. The difference is significant. Just gotta tweak the frequency response now so they play as nice as 4430's and hope I don't mess up the effect in the process. Even as-is, these are keepers.
Perhaps it's just a cheap trick, but I LIKE it.... :)
NL200t3 Zilchster Improved or N3134?
Zilch,
What is your preference between the two for a 4430 clone? Is the N3134 you built worth the extra cost and work? Have your mods to the NL200t3 closed the gap? Inquiring minds want to know!
