It's specs are exactly the same as original Times
Knock-off products like this are often sold by third-party salemen, who
are doing nothing more than advertising and moving boxes. Specs are
generated by those salesmen, not by engineers. Indeed, they may not even
be moving boxes, but sending orders to an un-named company that ships them.
Companies like Belden, Times, Davis, and DX Eng have real engineers --
their specs are based on their knowledge of what they're selling, their QC.
Another huge issue is quality control. How is the product tested? Will
what I buy today meet published specs? Will it be the same as what I
bought several years ago? And, as Bill noted, how does it stand up in
sunlight for ten years?
I had plenty of experience with "brokered" cable being substituted for
what I'd specified when designing and specifying large sound systems for
stadiums, churches, and performance spaces. My bid specs had a
requirement that any subs must have real engineering departments that
determine and verify specs for the product. When I asked one such cable
broker to connect me with their chief engineer, I asked about her
credentials. She told me that she got her EE degree from IBM. As you
might guess, I didn't allow the substitution. :)
