Does anyone have any info on the mods, "upgrade by Wisdom Audio consisting of a full planar line source upgrade and complete re-build of all 8 inch drivers - this includes a Wisdom Adrenaline Active x-over -processor"?

Looks like the EMIMs went bad and they replaced them with BG planar drivers, like this one:

Notice the wood patch where the EMITs used to be.

Pass.

I have to agree on the EMIM being replace with the BG. That just sucks. I am trying to figure out why they would do that to these speakers?

Maybe because keeping vintage EMIMs operating correctly, with their peeling, decomposing magnets and wrinkled, buzzing diaphragms is expensive and time consuming. These speakers aren't exactly priceless pieces of art, you can easily pick up a pair for much less than they sold for new. The Neo panels sound great BTW, and have none of the problems of aging EMIMs. Do a sweep on any vintage Infinity and you'll hear more buzzes, rattles and distortions than you will ever want to know about. I wouldn't mess up a pair of IRS V's with Neos, I'd make sure the magnets were right and order new diaphragms from Graz, but for a pair of RS1B's, 2.5's etc. I don't think it's a big deal.

Been years I know but someone said it, the emims are horrible drivers in every sense of the way. Never liked them , never will neo 8 would sweep the floor with emims all day long.

This technology has progressed tremendously over the decades. Also it's far more logical to make it a TRUE Line source, than the ridiculous quasi line source rs1b crap they did.

I have have a rs1b and it's the most lack luster speaker I own. It's really not that great to listen too , like you said here rattles, emims that have sagged diaphragms you name it. Now Ava offers them but for a rs1 that would amount to 1300usd worth if emim diaphragms.

No thanks...I might just part this one out or sell as it.

You're better of just getting a planar speaker and a good set of subs. Which I did, the rs1 has been collecting dust ever since.

I do get the infinity guys above here having this nostalgia for them. And the in "awe" seeing these speakers invoke is a factor too. I admit, first time I saw them "holy sh#t" once I got them and started playing around.

Meh ...whatever ! For its size heard and own lot better. Which is fine,. But like you said here emims can be easily bested. They are not magic or anything ...just expensive and maintenance heavy.
