Current affairs - Trystan’s moving house (again!) and I’m scrambling to get my demo room back together for an appointment in 2 days and the gear’s not finished! We continue our theory focus and move in to a discussion of crossovers - what do they do, and what are their component parts? Finally we get to talk about Trystan’s full range project and his impressions of the Tang Band full range drivers he’s chosen, and what else might be tried in future.
