Woofer and tweeter raw driver
in box measurements.
|
|
Speaker in-box response at 1 meter,
spliced with near-field woofer response
at 280Hz. Just about right to mate with
a sub at 90 Hz.
|
|
|
|
Woofer and tweeter filtered responses,
speaker in-box response with tweeter
both in and out of phase.
|
|
Crossover is 4th order LR at 2500Hz.

Close-up of the prototype electronics on a terminal strips. These "proto
boards" save a lot of time. Once a crossover topogy is detemined, it only
takes
about 2 hours to set a new target response, optimize it in Sound Easy,
and slap the new components onto the board.
