HOME THEATER CABINET This Russian Birch plywood cabinet system was built for my brother and his wife. It is made of 6 modular units, 3 small and 3 large. Each unit can hold 1 or 2 components. The unit backs are open to allow for airflow and add to the ease of hookup. The 6 units could be arranged and stacked differently if a new configuration is required. I also created a matching "cover" for the subwoofer, to the right of the unit. Each unit is very heavy, which should help with sound and vibration isolation. It was built over the winter of 2005.
