This system uses the 2-way crossover. A dimension
ratio of 1 : 1.618 : 0.618 provides cancellation of resonating frequencies inside the
enclosure. Port, driver, and tweeter should be centered vertically so they are in phase
with the listener's ear.
Then enter volume of
enclosure to calculate performance specifications. If only Qms and Qts are known,
press "Qts" button to calculate Qts. Qms and Qes are optional. Fs, Qts and
Vas must be entered.
