Not sure what that means...
What it does is at 120Hz it re-route the LF info to the amp and then to the Sub.
Not sure for the whole 700x series, but the BP7000SC proper is crossed to the sub at 80 Hz.
With your 2002 There are in fact three separate crossovers (Tri-wireable), if you were to remove the straps for the LF section you would need to use the RCA connection for LF. Where as the 700X does it automatically, and you can also use the LF input, which in my own experience is more sensitive and gives a slight boost in the LF volume.
Actually, I think they all have three crossovers. You're right about the 2002 and the connection straps. From the info I got from DT, it sounds like they are really using the LFE input to sum the LFE in with the mains, and that you should not set the sub control to "mains + LFE" or however the particular pre/pro/receiver calls it.
FWIW, I think I've played with all combinations of LFE in, full-range in, speaker wire only, etc. with the 2002s. I ended up coming from my amp to the mid/hi and using full range line-level signal from my pre/pro. I think this gives me a nice balance for music (to which I do not listen enough), but can be a little thin on the movie side. I'm also using a BFD to equalize each 2002 separately, and I'm using another BFD to EQ my M&K sub. The M&K is on the way out as far as I'm concerned, and I'm considering a 2x15" DIY or perhaps a 4x15" IB baffle in my ceiling (no manifold). We'll see...
