Within my floorstanding speaker cabinets I have a woofer and a horn, both 16 ohms. The connecting wires from the crossover to the speakers is fairly heavy. I thought 16 ohm speakers do best with a smaller diameter (higher number gauge) wire when connecting them to amps, so why are heavy wires used inside? The wires inside could easily have been changed by the previous owner and a mistake made, ....but maybe I am making the mistake in thinking they would be better off with thinner wire. Any comments?

Hi. Well yes. The large wires are fine and desirable. The gauge of the wire largely determines the resistance of the wire not what it is connected to. The higher impedance the load (16 ohms vs say 4ohms) the smaller the contribution of the wire will be. That means for a given amount of power wanted to transfer to the load the wire can be smaller. It does not need to be though. Larger gauge wire is always a plus as its lower resistance allows the amps to better "see" the speaker. This can have an effect on any negative feed back that the amp uses to control its response. Wires that are too small (thus having more resistance) will consume some of the amp power and turn it to heat. They will effectively reduce what is available to the speaker.

Good listening
Bruce

The speakers are Vitavox, ...built in the UK. 16 ohms. The sound is so good, it's like all my CD's are new again (but you must spend time with speakers like these, in lining them up right, both laterally and vertically).
