Thiel Owners

Hi Tom,

I was wondering if you would be willing to share the xover design of the CS2.7 or CS3.7.  I believe the mid+tweeter unit has separate xovers (vs. the 2.4 which is mechanical).  For the tweeter xover design, do you know if it has an electrical delay network to align the phase of the tweeter to the mid driver?  Or the phase alignment is done acoustically?

Thanks.

Great deal for someone in the Oregon area.

Nice catch!  Good to see you again.  Happy Listening!

Smoking good deal on those 2.4s. I’d almost buy ‘em just for the spare drivers. 10-12 hour drive for me during winter, no thanks.

Andy - I can share information, but can't send drawings until Thiel Audio's bankruptcy is settled.

You are correct; the 2.7 and 3.7 have 3 separate drivers with electrical crossovers, unlike the 2.4 which is electrically 2-way plus the mechanical mid-tweeter xo.

There is no time compensation in those crossovers. The coincident alignment is achieved geometrically via the position of the coaxial midrange and tweeter.
