Thiel Model 2

Sorry, can't help you with the Thiel 2's. FWIW, the Theil 1's and 3's were fairly easy amplifier loads. I'd suggest contacting the nice people at Thiel:

The earlier Thiel CS series weren't that difficult on amplifiers either. They stayed above 4 Ohms. Even the bass EQ'd 3.5's offset the demands of the EQ by gradualy pushing the impedance up where the bass EQ's kicked in.

02Pete,

I sold many pairs of the original 02 Model THIEL back in 1983/84, and was frankly dismayed when they elected to stop manufacturing them. At $350. for the pair, they were really, really good.
Jim Thiel told me that they were going to only offer the CS (coherent source) speakers from that point on. It was a business decision too, as we all have to realize I suppose that, taking someone out of the market with a $350. purchase may not have been wise. Also, they were looking to establish the kind of élan that lesser priced, non time aligned speakers and not 1st order crossover speakers would present to the marketplace.
At the time I was distressed, but now understand their thinking.

They were good speakers, and an amazing bargain...very flat with more than acceptable bass for a small cabinet.
They were efficient, (88db??) and an easy load to drive--they did NOT dip low in impedence as most of Jim's later designs.

Hope this helps.

Good listening,
Larry

hI larry. I know this is an old post but i was wondering if you remember who manufactured the mid/base drivers for these originally.  One of them is bad and I would like a suitable replacement for these great old guys

Welcome! stevevigneault

join our Thiel Owners thread and post your query there as well.
Hopefully, one of the guys can be of assistance to you.

Happy Listening!

Steven,
I frankly do not.
THIEL's new owners should be able to reference this for you, though.
Sorry for the delay in answering, I just now came back.
Best of luck.
LARRY
