Large Venue Speaker Cables

High Fidelity & Crisp Sound Signals

The cable that is used to drive loudspeaker loads is normally between 2Ω and 32Ω, although most systems are 4Ω and 8Ω. If the concern is to deliver amplifier power to the loudspeaker, as the case for most commercial sound applications, the design procedure is straightforward with cable resistance being the only concern. If the highest audio fidelity is needed, the cable construction will become an issue. The resistance of the cable is the most important electrical issue in loudspeaker installations. The effects of capacitance and inductance are negligible.

All large venues require larger speaker cables to handle the low impedance 4ohm and 8ohm systems.



Low Impedance Systems: output impedance is low, the current must be high in order to get a given amount of power to the speaker. The lower the resistance of the cable, the more power gets to the speaker.

In all speaker systems, 70V or low impedance 4Ω and 8Ω systems, the conductor type and resistance are the most important electrical characteristics. West Penn Wire provides Electrolytic Tough Pitch (ETP Copper), which provides close to 99.95% conductivity. We also use a higher strand count, which allows more skin effect and crisper signaling.
