I was thinking of getting the MJ Acoustics Pro 50 sub, since it's so highly rated by the hi-fi press, and, more importantly, the AV Forum. I understand that for £50 extra I can get the newer MJ Acoustics Ref 100, with 120 watt amp in a box with the same dimensions. Does anyone have any experience of it? I thought it would be better than the Pro 50, but I've just read a review of it in this month's Essential Home Cinema magazine where they only gave it 2 stars! The Pro 50 seemed to be 5 stars in all the mags, so I'm wondering whether I'd be better off getting one of those?
