I glued 1" dowels between the center baffle and the front and rear panels,about 12" apart.Seems ok,but would be better to have more.Since this was an experiment,one side panel was left unglued,just screwed with a gasket of duct tape,so it could be easily taken apart.It takes most of 2 sheets of ply/MDF to make 1 cabinet,with enough left to use for bracing.I will probably add more bracing eventually.
As it is,there is some vibration of the panels,(no audible)but with it in the garage,there is far more vibration of the garage wall than the box,so it is not a real concern at this time.
Cone excursion is surprising low,a bit difficult to see with the magnet facing out,and the opening down in the corner.I will try to come up with a more accurate method than sticking my finger against the cone,and use sine waves for a better point of reference.
