Model 1 woofer measurements

Recommended Posts

Boston Acoustics type (fillited) foams were used.

Values below are avg. of two separate woofer tests following fresh refoam with no breakin.

Fs=16.8 hz


Le=0.78 mH

Vas=7.5 Cu. Ft

Mms=70 grams

Sens.=87 dB


Although smaller in size (frame OD 10") the properties above resemble those of the AR3 series 11" woofer. The Cizek woofer even had a foam ring around the cone's surface about 2 inches up from the dust cap.
