Planning to pop into Sevenoaks tomorrow to have a listen to the MJ Acoustics Pro 50 sub-woofer. A unit which I have read excellent things about in a couple of magazine reviews, but nothing on this forum. This will be my first sub, I currently only have a B&W 600 series 2 set-up with no sub. Any advice on how to audition a sub would be most appreciated, and also what to listen to. I was thinking of taking Star Wars TPM and Saving Private Ryan on DVD. Andy P.
