Now we're getting somewhere. Thank you for the direct comparison and your opinion.
These are only 20mi away... If the seller doesn't have second thoughts or want a ridiculous price for them, I'll probably bite. Though I really don't have the room, and the wife may not be too happy about it... :)
Oh, and these are IV's, not IVa's. Doesn't appear there's much difference, though.
Thanks again.

There are some differences.
The mylar on the TIV mids is the same as the 3.7. While the Mylar on the IVa is half as thick like what is in the 20.7 mids. Not material if you are going to replace the mids anyway.
The bass panels on the IVa are slightly more efficient so you might get away with a 1kw bass amp while you might tax it on a TIV.
The other remaining diffeerence is that the mids on the IVa are longer and the crossover tuned 1/2 an octave lower.
OK, now you're just trying to make me nervous....1kW isn't enough! Holy Shi!
What can I say? I play loud. The figure is for 4 ohms
I use 2.5kw at 4 ohms and have strained the amp a bit.
If you have a smaller space you will not need the power on a continuous basis. An amp rated over 500W at 4 ohms and having a couple db dynamic headroom should do fine.
Did you ever see the posts from the guy with the IV panels for mid-bass, some Martin Logan for the mid (I forget which one), and an Emminent Tech fan sub custom built below his room that goes flat to 1Hz? WTF? Is there any music that would even use that sub? Sounds unbelievable, though. I want it!
The Tympani T-IV and Eminent Technology sub create an unbeatable
combination for stellar bass! As Satie has said many times the T-IV panels
should be braced (I still maintain that the two panels should also be "bolted together"
for even better defined bass. Rigidity of the panels makes a big improvement.
He posted his setup on the forum - the bass setup is a major project and required excavation of an underground transmission line bass loading system. The ESLs were Sequels IIRC..
The Neo8 are back on the market after having been unobtainable for a couple of years. You would want 6 per side. Not a small investment but it is a world class midrange driver.
Whatever your plans are, the TIV is a really very good large scale speaker with mod potential to levels you would not believe possible. Just be sure the speakers you are buying are in good condition commensurate with the asking price. Having a local pickup is just an incredible opportunity. Mine were shipped across the country.

Awesome. Wish me luck. No reply from the potential seller, yet.
I'd love these like a baby, if you're following, seller! :)
Anyway, if I do get them, I'll have plenty of questions about a NEO8 setup, amps, etc.
Thanks very much, Satie. Wonderful advice and information.
Best regards.
I wish you luck!!! and will be available to help as you tread up the upgrade path.
Well, sadly (for me, anyway), the seller decided to hang onto the TIV's. That's OK. I'll enjoy what I have for now. Thanks for all of the help, everyone.
FYI, the seller is a super nice guy. I think he feels bad about getting me excited to buy these. No worries. You probably saved me an argument with the wife! :)
Tell me about this Neo 8...did you build these? Are parts available? Quick search found eBay parts, but not much else.
i'm getting ahead of myself, I know. Hopefully no jinx. Crossed fingers. And toes!
