US Patent 11917359 Fir cable loop speakers system

A feeder/interconnection/return (FIR) Cable Loop System vastly improves the distribution, equalization, efficiency and power delivery of high performance multiple speaker systems, without the complexities and inherent inefficiencies of existing systems. This is achieved by a feeder cable which connects from an amplifier to the first speaker, while interconnecting cables connect all the speakers to each other. A return cable connects the last speaker back to the amplifier. This results in balanced power, significant improvement in frequency response, and dynamic range.
