- Geddes Approach on Multi-Sub Bass Optimization: Video PresentationAV NIRVANA is happy to release one of our first video presentations addressing technical topics. This video is on the multi-sub approach developed by Earl Geddes, a man I consider an important mentor and influencer of my own views on audio. This is a presentation I gave at a friends Home Theater GTG discussing low frequencies in small rooms and the use of Geddes multi-sub approach. Please put any comments or questions below.
