Not sure where to post this as I'm not a dealer or manufacturer, just a keen audio DIYer. But I have produced a kit, the DBR-100, for the TB W4-657D full ranger in a double bass reflex enclosure.

The DBR-100 kit includes all the parts required to build a pair of speakers and 14 precision CNC machined 18mm MDF cabinet panels with slots and rebates for accurate and easy assembly. (Panels for one enclosure shown above).
Hardware includes drivers, port tubes, terminal plates, acoustic wadding, connecting wire, solder, screws, gasket tape and filter coils.
