I was planning on putting the SMS-1 in my living room. So the only adjustments I will have are the RR2150's crossover point and the volume level on the LFM/1c.

Are you stating that I can use the SMS-1 on a temporary basis to generate the necessary frequencies to match the system and perhaps pick the best RR2150 x-over point? If so that is a lot better than buying a disk like the Rives Audio Test CD-2 for a 5 to 10 minute one time use?
