Pro-9 Plus Bi-Wire

About the Pro-9 Plus Bi-Wire

The Harmonic Technology Pro-9 Plus Bi-Wire speaker cable is designed with separate woofer and tweeter sets within one jacket, allowing for internal bi-wiring. It uses 9 AWG wire made from the highest purity Single Crystal Copper (OCC Copper) to virtually eliminate distortion and coloration. The cable features advanced insulation materials including soft PE and high-tech Teflon, improving flexibility and reducing inductance and capacitance for extremely accurate sound transfer. The Pro-9 Plus Bi-Wire cable delivers tight, dynamic bass, exceptionally rich mid-range with harmonic completeness, and smooth, detailed highs without artificial zing. It supports a holographic soundstage with depth and roundness, outperforming many existing speaker cables. This cable is suitable for large speakers and powerful amplifiers, and it is an improved version preceding the Pro-9 Reference SE series. The design also includes air-tube technology to separate conductors and reduce cross-talk, enhancing overall audio fidelity.
