9/2/2023 0 Comments Speaker wire for home theater![]() ![]() There can be a synergy between a particular speaker and a particular speaker wire. For comparison, common lamp cord, sometimes called “zip” cord, is 18 gauge. So, a 24-gauge wire is half the diameter of a 12-gauge (and about one fourth the impedance). ![]() Counter intuitively, the higher the “gauge” of the wire, the thinner it is. For the wire’s impedance, thickness (gauge) of the conductor and the length of run from amp to speaker are the major concern. The location and depth of the dips in the frequency response depend on the speaker’s impedance and wire’s impedance. There is an interaction between a speaker cable and a particular speaker. (Impedance can be thought of as the difficulty of electrical signal passing through a wire and is measured in ohms.) So, if the wire has over about 5% of the lowest impedance of the speaker, a dip in response can become audible. Principally, there is one reason for this: the impedance of the wire is fixed but the impedance of the speaker varies widely with frequency. The answer is YES! And this has been repeatedly demonstrated in blind testing as well as sighted evaluation. Yet, the question remains in many minds does it really make a difference? The wire connection between an amplifier and a speaker has been the subject of a great deal of discussion – and the expenditure of a great deal of money – for more than 30 years. ![]()
