I love factory tour photo galleries. They provide great insight into the complexity that goes into our audio and home theater products. These particular photos are from a Sound Vision magazine article and cover the Anthem / Paradigm facilities in Canada. My favorite picture, being an acoustician, is one of their huge anechoic chamber that they use for speaker development.
If you like this kind of thing you may also be interested in the JL Audio factory tour that I blogged about a while ago.
