FYI, the factory says there is only a 1C as of 2/14/02.
Now, it wasn't Richard, but the woman seemed pretty well checked out on other matters: 350.00 w/return freight to update a Ce greater than serial 77000 to a Signature; 15.00 to run the computer qc on a returned pair, 60.00 per 2 family speaker for a new sock; how to remove the sock to check the tweeter; that 2Ce models were made until 1/2001; and, that the 2Wq does not have the same adjustment system as the 5, only a q control. That's pretty specific information. Try contacting Infinity by email or phone and getting a "coherent" response like that.
She could have been mistaken, but then I ask you again exactly how is a 1Ce different from a 1C and where can I get one?
