I recently built a pair of 2 Pi Towers. Wayne supplied the basic plans ahead of time so I could have the cabinets ready for the components. I did a lot of searching on the forum for 'best practices' to consider when building the cabinets.Wayne supplies an easy plug-and-play solution. Everything from the binding posts for the back of the speakers to the spades you plug into the drivers are pre-wired. You just connect the spades to the drivers, drop the drivers and binding posts in the holes you cut and screw them in (you supply the screws). You even get two Pi stickers to affix to your speakers.
