A 4520 for small doors (like mine).
Response is nearly at orig. 4520, exept a few Hz loss in low, because of reduced length, i think. But it will work at 40 Hz or lower, because my 4530 works at 40 Hz (corner) also (measured and i can hear it).
Loss is only in reduced Rearchamber volume of driver and a few Millimeters in the beginning of the horn (Throat?).
