AB  - Various software based measurement systems can be used for live sound measurements with music or speech signals in occupied concert halls with sufficient accuracy. However for some special applications as measuring the performance of a ground-stacked bass array component of a multiple component sound reinforcement system in an occupied hall, these systems can't be used directly, since it is not possible to run a bass array alone during a concert. A simple method to obtain the subwoofers' impulse response using program signal measurements of a full range PA system is proposed. The desired impulse response results from subtraction of full system impulse responses with and without subwoofers running. Required measurement conditions and limitations are discussed.
