Tips & Tricks:
Plan all cuts well and make all table saw cuts of the same length together, this way all pieces will be the tightest tolerance.
In retrospect, I would have used quality plywood for the internal, mounting, baffle. This way the T-nuts would be more secure than in the MDF.
Use masking tape to hold Tnuts in place. I had a couple that kept falling out which was a pain because you have to remove the driver to replace them.

Still tweaking to get best sound, but overall very pleased. Bass is low, powerful but not boomy

About the Designer:
