Putting together a 5.1 speaker system for a larger basement. I will do either on or in-wall speakers with a sub. My initial thought was to do a in wall with a 6.5 - 8' woofer and cross them over around 60-70hz. Thought having the LCR's handle some of the mid bass might make it sound better. I went into a local, well respected audio shop and the sales guy recommended two speakers that only drop to 80hz. What are everyone's thoughts here. Budget is around 3k for 3 in/on-walls, 2 in ceiling surrounds and a sub.
Here is what I have considered:
Paradigm AMS LCR
Golden Ear Super Sat 50
