Cable choice consists mainly of selecting the corr ect cr oss se ctiona l area in relation to the cable length and the load impedance. A small cross sectional area woul d increase the cables series resistance, inducing power loss and resp onse variat ions (dampi ng facto r). Connectors should b e wired with a minimum of 2.5 sq. mm (12 gauge) cable.[...]

5. Amplification & Power Handling As with all professional loudspeake r systems, the power handli ng is a functi on of voice coil thermal capacity. Care sh ould be take n to avoid running the amplifier into clip (clipping is the end result of overd riving a ny amplif ier). Dam age to the loudsp eaker will be sustained if the amplifier is driven[...]

8. Arraying As discussed in the previous sect ion, comb filtering is a phenom enon, which cannot no t be cured by equalisation. Small alterations to loudspeaker positions can have the effect of minimising problematic combing frequencies. Arrays should be const ructed so that the individu al coverage patters of each loudspeaker combin e with mini ma[...]
