All X21 subwoofer cabinets are customized for each individual driver model. Driver performance data in the cabinet is provided for each driver on the page for the driver manufacturer. All driver openings and recesses are specific to the driver and tee-nuts are installed for mounting drivers and one Bi-Amp Speaker Terminal Cup Gold Insulated Binding Post High Power (UPC 848864017778). Screws are also provided so that you don't need to hunt for hardware. The X21 also includes port tubes and a magnetically attached grill. Port tubes are pre-installed in finished cabinets and ship un-installed for raw MDF cabinets in order to permit finishing. Only water-based lacquer and stain finishes are used on finished cabinets. Order your favorite driver and terminal cup (UPC848864017778) from your favorite parts suppliers, install insulation, the driver and terminal cup; no machining is required.
