All REL, MJ Acoustics and Ruark subs 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 REL explains 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 £49.95 a piece and I believe this is probably the cheapest way of buying a 15 Metre Speakon High Level Lead, It’s even cheaper than buying from our own website as it’s an ebay special.

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.
