I’ve been reading a bit about the use of multiple subwoofers to improve bass response and/or to reduce spatial variation in the response. In particular, the paper “Low-Frequency Optimization Using Multiple Subwoofers” by Todd Welti and Allan Devantier shows how placement of multiple subwoofers can be used to optimize response or spatial variation. They document the results from running a search algorithm over a multi-dimensional space defined by: The particular combination of subwoofers selected (two or four out of eight, in the most interesting part of the paper) The gain of each subwoofer The delay of each subwoofer The frequency and cut of a singleRead More →
