What kind of audio cable do I need for a subwoofer?
This 1 to 2 RCA male 15-foot audio cable is double shielded for minimal interference for exceptional sound quality. This 1 to 2 RCA male 15-foot audio cable is double shielded for minimal interference for exceptional sound quality.
When was the RCA subwoofer cable first invented?
The RCA cable was invented by Radio Corporation of America in the 1940s and initially designed to connect an amplifier to a phonograph. It stands out by an RCA end connector that is called a “wellhead”.
Can a ground loop be used on a subwoofer?
a ground loop allows the hum of 60Hz to travel on the coaxial cable shield. A subwoofer frequency range influences hum greatly. Thus, if an RCA cable connected to a subwoofer is equipped with extra shielding, it allows reducing hum from induction. However, it doesn’t work with a ground loop.
Which is better RCA or AmazonBasics subwoofer cable?
The cable is well-built (equipped with RCA connectors that corrosion-resistant) and decently copes with its functions (carries low-frequency signals, providing superb sound and bass). Another advantage is its great length. By the way, AmazonBasics Subwoofer Cable can be purchased in different lengths.
