QED Profile Subwoofer is the smallest analog interconnect cable model for subwoofers (RCA mono - RCA mono). QED Profile Subwoofer is a compact and flexible cable, which offers very good audio performance and exceptional physical resistance. The cable is made of OFC copper with 99.999% purity. The conductors used are soldered, and the outer jacket is extremely flexible and allows access to difficult positions without endangering the integrity of the cable. Also, the plugs are miniature and allow connections in difficult places for normal cables. The cable is shielded, as protection for external interference, and the contacts of the plugs are gold-plated (24k). The outer diameter of the cable is only 4 mm, which allows an easy and discreet installation.
