it is one thing to buy some cone based drivers and build an enclosure by copying the R&D of an established and eminent manf.
it is something else to hire a bunch of engineers and acousticians, but them test gear, including laser interferometers, and spend years to improve on an existing design of cones in a box
and something else again to create speaker based on ribbons, electrostatics, or a gas plasma
choose your level and how much time you want to invest for the $$ you will save (I suggest the cones in a box for any single individual)
Just remember, Edgar Villchur died for your sins
