A coaxial driver will be used rather than two separate drivers – the tweeter is centered in the driver. This gives very good coherence enabling a great sound stage and is a method used by some big name manufacturers for this reason.
The driver is a Seas C16N001/F a 16cm unit with a magnesium cone. C16N001_datasheet
Hypex FA122 Fusion plate amplifiers provides us with an amp each for the tweeter and the driver.
The cabinet will be laminated from birch ply over a custom form with a choice of final outer veneer and will end up being circa 20mm thick. The cabinet will be subdivided between the driver space and the amplifier space. The legs fixed to the cabinet place the drivers at the right height for listening when sitting down.
The baffle will appear to be 1cm thick but will actually be 30mm thick to provide the lack of movement needed. Veneered in a European hardwood of choice I heartily recommend that we go ahead and bookmatch the pair. Edges will be solid and rounded over for better sound dispersion.
Legs will be solid wood in a hardwood of choice to be agreed.
This finish of the laminated sides would need to be varnished but the baffle can be finished in a wax oil.
