FACTORS IN THE DESIGN OF LOUDSPEAKER CABINETS

H.D. Harwood, B.Sc. R. Mathews

Summary

The mechanical properties of timber, wood products and other materials potentially suitable for the construction of loudspeaker cabinets have been measured and details of the results are given. Various commercially available damping materials have also been assessed and their relative efficiencies are listed. A new method of test for the cabinets of completed loudspeakers has been devised and a tentative performance specification has been produced
