Hi

I do not have a reliable B&W Hi-Fi shop where I live so I was
wondering if anybody here could help me?

I would like to buy the following:

2 x 604 S3 (front speakers)
2 x 603 S3 (rear speakers)
1 x LCR 600 (center)

my questions a

1. could / should I replace the LCR 600 with the LCR 60 (I currently
have a very cheap offer for these speakers)

2. do I need a sub-woofer or will the 604' be good enough?

Thanking you for any help given
