Speaker Quad consists of four individual cables with a large total cross-sectional area, and features a very careful, sophisticated design aimed at frequency-neutral behaviour and a very good specification. Its internal construction, based on four independent conductors, permits several different types of connection; for example, the use of four banana plugs or spades for connecting loudspeakers with bi-wiring terminals. The high-end BFA banana plugs and spades terminals are manufactured from chrome-plated ultra-pure brass, and feature an insulating plastic grip.
