I have a quick question about my 683 speakers (s1) that I'm hoping maybe Patrick will chime in on, but anyone else who knows, please by all means let me know. The specs for my speakers say that the lower end of the frequency response (+/-3db) is at 38 Hz. I noticed that the specs for the new 683 S2s have the lower end of the FR listed at 52 Hz, and even the new CM10s with their extra bass driver shows the lower end at something like 42 Hz, still a little above the 683 S1s.
My question is: Does this reflect a difference in design? If so I'm curious about the philosophy behind it? Or are the specs of the older (or newer?) 683 not accurate? Thanks in advance.
