Interesting thread, wish I knew more about subs. I have a set-up where I'd benefit from a sub, I'd appreciate some guidance. I have a bedroom setup with a Linn Classik integrated (amp, preamp, tuner, CDP) and four B&W LM1 lifestyle monitors. I'd like to add a very small and relatively inexpensive sub to help out on the bottom end. WAF is a huge issue as you can imagine. Any and all ideas would be most welcome. Jeff
