Two Crossover Frequencies in Center Channel Speaker Spec
I am starting to put together my first home theater and came across something I don't understand in some of the Klipsch center channel speaker specs. They are listing 2 crossover frequencies with only two speaker sizes in an enclosure, a woofer and a tweeter. For example:
RC-64 III: 1,000 Hz & 1,400 Hz
RP-504 or 404C: 500Hz/1500Hz
If these boxes had an WMTW or WMTMW configuration, I would understand that they are switching between woofers and mid-range, then between mid-range and tweeter. However, the above enclosures only have two speaker sizes, 6 in + tweeter in the 64, 5 in + tweeter in the 504, and 4 in + tweeter in the 404. Obviously, they have four woofers in each box. So, are they driving one pair as "woofers" and another pair as "mids"? How does that work when the "woofers" and "mids" are the same size? Also, the "mid" frequency range seems really narrow, especially in the RC-64...
Can someone explain what they are doing here?
