General presentation Cable QED Reference XT400
XT 400 is a silver-plated OFC copper speaker cable in an X-Tube™ construction, with a section of 4 mm2. XT 400 is the silver version of the famous X40, one of the most successful speaker cables produced by the British company QED.
The QED Reference range uses an extremely high-performance, low-density polyethylene dielectric. It allows the substantial reduction of signal losses due to the capacity of the cable.
The conductor used is multifilar, 99.999% OFC (oxygen-free copper), silver-plated. The XT400 has a useful section of 4 mm2, excellent for connecting high-power amplifiers to gourmet speakers, even at greater distances than usual.
