I don't quote follow what you mean by "to bring drawing in the wood" (unless you mean marking and cutting), but if you want to 3D print some of the parts, there are places where you can add a wood or metal fill to a PLA base to increase its stiffness. I haven't made any speaker enclosures, but I have been considering it.
There are other sites that will use CNC on "production grade" wood. Whether you can get the type of wood you prefer for your enclosures would be something you'd have to ask them. One site is https://www.nealscnc.com/
; they specify both hardwood and plywood, along with laminates and "engineered wood" (whatever that is). If you want to experiment with transparent materials, they also cut acrylic/plexiglas. A bit of research indicated that HDPE (the stuff used in cutting boards) is acoustically quiet, if not actually dead.
Of course, if you decide to offload your production, try to find a place nearby so you can minimize shipping costs.
