Loudspeaker design and analysis

This presentation will demonstrate the planning, construction, testing, and final performance of a student designed loudspeaker system. The purpose of this project was to create a 2.1 channel, high quality sound system that produces a bandwidth just short of the full range of human hearing, which is then cut off and sent to the appropriate speakers. This system consists of 2 two-way speakers utilizing a woofer and tweeter, arranged in unison with one sole subwoofer. The function of this particular sound system is to reproduce sound faithfully in a 350–400 square foot room, yet still be lightweight and maneuverable. The performance characteristics of this system will be presented through frequency response and linearity testing results. These tests were used to help warrant modifications made to the cabinet size and shape while adhering to a strict budget of $1,200. The analysis of every performance will also reveal data for different electrical component values in designing the Linkwitz-Riley crossovers. The aim of this presentation is to highlight the various key factors that are important in loudspeaker design.
