We have been huge fans of the REL range of subwoofers since the 1990's when REL intorduced their first range of subwoofers. REL Subwoofers are unique in offering both Line Level (RCA and XLR depending on model) and High Level input options, which can have big benefits when integrating the subwoofer with the main loudspeakers or for use with a Hi-Fi Amplifier which lacks a dedicated subwoofer output. 

The brand new Serie/S S550 and S850 subwoofers are a huge step up in perofrmance from the already very good preceeding models. The new wooden grille, available as an optional extra, adds a new dimension of style into the REL Acoustics range.
