Thiel Owners

My 3.7s have pink fiberglass insulation in the mid/tweeter compartment.  Maybe switching to wool could be a part of an upgrade?

@tomthiel - Hi, Tom! In another Thiel related thread, you offered to share your take on why there wasn’t a CS4-series speaker. Wondering if you wouldn’t mind sharing that story here?

Thanks again for enriching these discussions!

Larry, It's been  a long time, and I might be mistaken, but I thought the late "Bud" Fried also thought 1st order cross-overs were "all wrong". I seem to recall that some of his designs were supposed to be based on transmission line cabinets, yet none appeared to be suitably ginormous enough to be actual transmission lines. Also, wasn't there some sort of brouhaha with Stereophile over the measured bass output of his speakers vs. Thiel's, wherein Stereophile reexamined their procedure; to find that they were in fact correct.

Tomthiel, Interesting that you used Krell's  (though I can understand why)  for developing the CS5's, it's been long rumored it was the 250 Class A Watt mono Threshold 12e's.

A good amp for current hungry Thiels doubles power from 8 to 4 ohms and again doubles or nearly so into 2 ohms.

Neither Ayre or Pass give a 2 Ohm rating for the amps F1 is considering. I’m not convinced, however, that matters for a CS2.4. Unless you like to listen at *really* high SPLs and/or have a large room, either amp sound be more than enough to deliver musical bliss. Interesting observation, though, that something in the, um, Ayre might have caused the blown coax. I wonder what that might be.

The CS5, though, looks to be a supremely current hungry speaker. Stereophile’s measurement shows the impedance dropping <2 Ohm in the bass! Might not want to drive those with a SET :)

The observation of congestion of orchestral climaxes at high SPLs suggests, to me, the onset of clipping. Probably need a more powerful amp if that’s how you like to listen.
