I have a pair of Polk RTA 12 speakers that I am refinishing and will be designing a new top to replace the black 'hats' that came with these. I want to design a new top out of wood (my choice for this project is cherry) to enclose the tweeter and crossover.
As designed the tweeter sits 3 1/4" back from the front edge (and other drivers). The tweeter has the phase reversed to compensate for the time shift. I am thinking about moving the entire array forward so the tweeter is aligned with the other drivers, but I don't want to distort the image. If I move it forward, it would be mounted similar to a Monitor 7 or 10. I am pretty sure I need to reverse the phase from how it is now. Is that my only concern, or would moving it distort / change the image?
I want this top to be 'plug and play' with the least modification possible done to the speakers. If I move it forward, I can use the two metal posts as guides for mounting this, along with the screws that currently hold the crossover in place.
