Home installation design and performance of an exponential low-frequency horn
Arthur L. Newcomb · IEEE Transactions on Audio and Electroacoustics · 1967
An 18-foot exponential low-frequency horn has been designed and built for use in a home sound system. The horn mixes stereo information below 125 Hz with satisfactory performance down to below 40 Hz. A description of design procedures and violations is given and some curves are provided showing effects of room geometry at three points in the listening area.
