That was a great response JK with very useful information! I'm not clear on the ICBM however. Why is it necessary?I would assume that normal stereo does not have bass management even when people are using LF bookshelf speakers. Don't speakers naturally cut off when the signal is below it's capabilities? Why is it a concern in this application?
I wonder if it's worth the added cost, not to mention another set of cables.

You're right to be concerned about the extra cost and cabling, but for me, it's worth it. The DVD/SACD player I'm using has two choices for speaker responce, full range or cutoff at 120 hz. While it's true that even a small bookshelf speaker can be fed a full range signal, the fact that it's bass responce is so limited means that a portion of the music/soundtrack is not heard. Being able to route that missing information to a well placed subwoofer makes a BIG difference. Also, using the factory cutoff setting of 120hz. is too high, IMHO, especially for the center channel speaker. The ICBM allows you to determine the lowest (but safe) bass level you can go for each speaker, then send the rest to the sub. Played the DVD "The Matrix" before installing my ICBM, the lack of bass material made the soundtrack high-pitched and ear piercing. After installation, much more involving, from all channels. Go to their web site, you can download the owner's manual, tells you everthing you need to know.
