I will probably answer my own question, but lets ask.

I currently have a Yamaha YST-SW160 that I bought back in 2002. I used it for a while in my family room, then disconnected it (I can't remember why). I remember enjoying it.

I am ready to buy the 990/7500 combo. Is it worth it to add the LFM-1 as part of the combo for only an additional $399 (a savings of $180 from the base price)? or try out the YST-SW160 in the new basement (It is a large open room).

I am guessing the YST won't work that well, but the LFM-1 by it self or in combo with the YST will work great.
