Illuminati (33rd Degree)

PiAlign recommends 4.0ft3 tuned to 50Hz using a rectangular 5.8" x 10.3" port that's 9.2" long. Response is nice and flat with f3 of 60Hz and f10 of 40Hz. A four π-18 cabinet is a good choice also, providing an EBS alignment having a -3dB shelf from 40Hz-100Hz. Response is nice and flat in the shelved region with a slight 3dB rise through the 100Hz - 200Hz octave. Considering the shelved region as the baseline, f3 is 40Hz and f10 is 30Hz in the four π-18 cabinet.
