The enclosure is constructed of precision CNC cut 3/4" MDF then assembled with polyurethane glue for superior strength. An internal brace is also utilized to minimize cabinet resonances. The enclosure is pre-drilled and cut for the amplifier,driver, and spikes, so after some assembly (an hour or so), this is essentially a plug-n-play system. The easy assembly went as follows: cut and apply 2-1/2" foam to all internal panels, mount the amplifier, connect and mount the driver, and insert spikes.
