I'm trying to wrap my head around speaker building theory (and it hurts, believe me
), and one topic came up that really puzzles me - passive radiators. How does a rear-mounted PR NOT create an out-of-phase sound wave in relation to the front-mounted driver? I imagine that they must move in lock-step, but maybe that's where I'm wrong. Is it an inertia effect that prevents it from happening (i.e.: delay in getting the mass of the PR moving)? Otherwise, you'd think that the PR would just bounce the back-wave of the driver off the wall behind the physical box (facing the PR), creating an out-of-phase waveform.
I know that they do work - I still have a really old pair of Klipsch KG-4's that have a large PR in the back, it's just "why" they work that's hanging me up.
Go easy on me - I'm new to this...
