We make sure that every front plate will fit with every cajón, because the
shape and hole positioning is made with a computerised machinery and
procedure. The receiving holes on the cajón are also placed with a
computerised procedure, so a new front plate will match exactly into the
cajón that you have, perfectly straight and centred. This will save money
in the long run, and it also allows room for changing finishes and types of
materials.

The beating surface, which is thinner than the rest of they cajón will
receive a constant stress, so it will wear out faster than the resonating
box. It could be because the material of the tapa and the body of the
instrument is wood in both case, but the fact is that most manufacturers
make cajons as a unique object, with tapa and body of the instrument
finished and bound together. In those cases, when the tapa wears out due
to the prolonged percussive action, it is difficult to change it over, because
the new front plate would have to be contoured and sanded again on top of
the instrument, but not every percussionist may have the adequate tools
or the necessary skill to do that. The RTS system overcomes this problem:
by reducing slightly the size of the tapa, it becomes possible to fit it onto
the body of the cajón without disrupting response from the instrument or
playing comfort.
