Low frequency amplification for live sound aplication

Abstract

This thesis offers insight to the issue of subwoolfer amplification in live sound application. The introduction discusses the role of subwoofers in sound practices and the impact of low-frequency spectrum of the human body. It describes a creation of PA system as process of design, construction and final control measurement. In first part thesis deals with principles of connecting several subwoolfer sources to the systems - Arrays. It describes Radiation patterns and evaluates consistency of sound field on low frequency range. Further part of work follow up the application of delay of whole system or its parts, Beam steering. The aim of this work is to evaluate particular systems from practical point of view when used in interiors and exteriors on so called "Open air" venues
