Illuminati (33rd Degree)

The Alpha 12 works best on open baffles or large vented cabinets from 4.5ft3 to 60ft3 tuned to 20-25Hz. When going with a vented cabinet, the box size can really get excessive. But you can get acceptable results at the smaller end of the scale. PiAlign recommends 4.75ft3 and 22Hz Helmholtz frequency for the Alpha 12.
