R&D Report 1992-08 : Low-frequency room responses: Part 1 -- Background and qualitative considerations R. Walker The problems inherent in the reproduction of high-quality sound in relatively small rooms are discussed. Methods of predicting the inevitably uneven low-frequency response from source to listener or microphone are also discussed. It is concluded that, even with perfect prediction methods. there would still be some compromises which could only be resolved by making subjective judgements. The use of additional, low-frequency loudspeakers in control rooms permits an extra degree of freedom in the positioning of the loudspeakers to obtain the maximum degree of uniformity in response without compromising the stereophonic image localisation.
