Inspired by hjames' "references threads", I've collected links related to Westlake, Eastlake and Hidley Design below. Please PM me if you want me to add something. (Just in case: Many Westlake speakers feature JBL drivers, and the Smith horn is essentially a modified JBL 2397, hence the "Lansing heritage". The common denominator between said three companies is the pioneer studio designer Tom Hidley.)
