"....Depending on your gear, there may be another way to connect your sub that would actually offer benefits to your system..."
OPTION
-- Longer length RCA interconnects direct from your preamp outs plugged into your RCA inputs on your subwoofer.
That way your bi-wire speaker cables from your amp to your speakers remain undisturbed "as-is".
What I did:
I Bought Klotz AC110 bulk cable (10metres) and then had the pair of 5metre lengths professional terminated with Neutrik Profi RCA connectors to serve as the ICs to the subwoofer.
Note: (These are exactly the component parts that the REGA "Couple" ICs are made with, and actually made for REGA by KLOTZ....)
I bought the Neutrik Profi RCA connectors on EBay and bought the bulk cable separately directly from a German cable/ parts supplier ... Much cheaper cuz KLOTZ is a German cable.
I use Nordost Freys as my main ICs and these REGA Couple interconnect clones are no slouches by comparison regardless. They are outstanding in their subwoofer role.
PS:
I bought an extra 10 metres of cable and another pair of Neutrik Profi RCA connectors to serve as a swap-in HT subwoofer cable for my other HT subwoofer , and is as good as my expensive NORDOST HT subwoofer cable.
