If you look back some pages you will find pictures of my build.\n\nIf i recall correctly you will need one and a half sheet for this build, but one venered should be enough as the rest is hidden.\n\nAs long as you have access to CNC i would go for the veneered and mitre all joints. It is possible to do by hand, but it take some skill as every minor defect will show.\n\nI'll pick up 2 sheets of the cherry veneered 3\/4" MDF and we're going to practice lock miter joints and "miter folding" to get better at it before attempting the speaker cabinets. We want those to be as close to defect-free as is practically possible. We'll also be doing sample finishes and stains to find what looks best, and how good of a true shine we can get on them. I don't expect to be a Jim Salk in a couple on months, just don't want the job looking hacked.\n\nThe CNC machine I have is a metal-working one, a "Bridgeport clone" with a Prototrak control. It's not a CNC router, but we may use it to cut the round holes & counterbores for the drivers. I'd done that when my son built a subwoofer enclosure for his pickup truck.
