REL, MJ Acoustics, BK Electronics and Ruark subs all have a Speakon High Level input, so have some ProAc such as the ER1 and Rega’s Vulcan. This is to use a professional cable to hook their subs up to any amp. This is what you need to hook your sub up to your Hi Fi (red, yellow and black ends attach to speaker outputs alongside existing speaker cable - shown in pics.) It's very simple to do and I believe MJ Acoustics and REL explain better on their website.

These cables are also recommended for AV use in conjunction with a single mono LF signal (the usual sub input for AV), as using both gives better response to the low frequency signals your AV amp gives out. Again, check out the MJ Acoustics website for more details. These cable’s can retail at up to £30.00 a piece.

Please note that the older RELs used an XLR connector rather than a Neutrik Speakon NL4FX for their high level input ,so please check before buying, it's quite obvious if you have a look at your sub inputs.

Please let us know if you have an MJ subwoofer as their lead is slightly different to all the other leads
