The problem of sizable and highly audible frequency-response dips introduced into the upper-bass and lower-midrange response of a loudspeaker in a room by reflections from the nearest corner is much ignored and/or poorly understood by consumers and designers. Placing speakers on stands commonly aggravates matters. Measurements of an equalized-flat 6-inch loudspeaker variously positioned in two real rooms show the extent and severity of the problem and demonstrate effective, simple countermeasures. A free software spreadsheet program which analyzes and graphs the problem theoretically is also described and compared with the measurements in order to gauge its predictive value.
