What is Bi-amping/Tri-amping and What are the Advantages?
Biamplification (using a 2-way active crossover) and triamplification (use of a 3-way active crossover) involves using a number of amplifiers, each assigned to a certain frequency bandwidth through the use of an active crossover. (Or many in larger applications) Passive and active crossover combinations can even allow for 4-way triamplified systems (the “bi” and “tri” do not indicate the number of sections in the speaker, but refer to the number of amplifier sections handling various frequency bandwidths.) Bi-amping and tri-amping is done for a number of various reasons: 1)To reduce distortion- High-energy bass, especially in modern music requires a considerable amount of amplifier power. Low frequencies use up most of the amplifier power, leaving none for the high frequencies. When an active crossover is used, the high frequencies are driven by a separate amplifier, therefore eliminating distortion and increasing the headroom of the system. 2)To increase headroom- Bi-amping / tri-ampi
