Mitered box question

[MTbassbone]

Hi, I am making a speaker box and would like to use mitered joints to hide the edges of the plywood. My plan is to use the track saw and MFT. After making the initial 45 degree cut I would need to rotate the piece 180 degrees to but miter on the other end. Will this compromise the squareness of the cut since I will be referencing a different edge against the fence? I plan on ripping long pieces of the plywood with parallel guides but still. have to wonder if this would cause an issue.

FWIW...I'd consider going with a lock mitre joint, it's what JBL has been using for the last 50 years and is acoustically preferred because of the additional glue surfaces. The additional glue surfaces prevent material separation and prevent potential resonance issues.

I think Totem Acoustics does that too. I have an OF1010 router but have not invested or made a router table yet. Maybe next go around. I am just going to use dominos and glue this go around.

Well carry on...it will be very interesting to hear about your results. Obviously, manufacturing methods have changed over the years and it will be interesting if the Domino method will be equal/superior to the lock mitre method for speaker enclosures. I have no dog in this fight. And thinking about this a little bit more, maybe it's a combination of glue choice along with construction choice that renders the lock mitre obsolete.
