INTRO by Black Rhodium All Intro Products INTROLINKS
The secret for success for installing INTROLINKS in your music system is to insert your loudspeaker cables into the TWEETER or HIGH FREQUENCY terminals of your loudspeaker.
This places your bass / mid-range speaker drivers in series with the large ferrite in the links.
280mm in length, from tip to tip, with spade connectors one side, and 4mm connectors on the other side.
This is more effective because the bass / mid-range speaker drivers handle about 90% of the energy from the amplifier. The large ferrite core under the heat shrink label will filter out a lot of distortion in your cable.
Your loudspeakers will sound much better if you connect them this way.
