Bolts for drivers?

[Rimbaud]

davef: Have you considered a future change to the Sierra cabinets to include embedded nuts on the interior side of the baffle, to allow for use of bolts rather than wood screws to install the drivers?

You've already shown your commitment to supporting current Sierra owners with upgrades - this would further facilitate that goal by enabling repeated removal/installation of drivers without the diminishing tightness of the wood screw-to-bamboo interface.

Bamboo seems better than MDF in that regard, but bolts (preferably Torx-head) would increase the overall build quality just the same.
