Ev pro sound speaker plans

[mixmaster]

Hello,
does anyone out there know where I can get the old vintage speaker cabinet plans? like the electrovoice patrician IVs or vintage jbls bass reflex rear firing corners?

You can get the plan by driver model, not brand name.
For example, EV will provide plans for EVX or EVM 12-15 inch speaker, etc...but not the plan for the commercial finished version, like patrician 4.
so find out what EV driver (speaker) you are using first, get their EV plan by speaker number, and design whatever mid / high frequency you plan to include...
