Loudspeaker Enclosure Materials (Part 2)



In the second part of his report on Loudspeaker Enclosure Materials, Mike Klasco focuses on new and improved materials alternatives. The report details how new materials offer a valuable alternative to injection-molded thin-wall lightweight plastics, without the expense of sonic integrity.
