I've been recommended the MJ acoustic PRO 50 sub from a sevenoaks salesman, but I'm having trouble finding a review of it. Can anyone recommend it ? I'll be buying some B&W 602 S3 for the front and a LCR60 centre channel at the same time. (I'll use some old mission speakers for the rears for the time being). I saw a one line summary for the PRO 100 in a mag, but it said that it was 100w so I'm thinking that maybe the PRO 50 is a little under powered. cheers.
