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.

Sono state utilizzate schiume tipo Boston Acoustics (riempite).

I valori seguenti sono medi. di due test separati del woofer a seguito di una nuova schiuma senza rotture.

Fs = 16,8 Hz

Qts = 0,025

Le = 0,78 mH

Vas = 7,5 Cu. Ft

Mms = 70 grammi

Sens. = 87 dB

BL = 9,25

Sebbene di dimensioni inferiori (diametro esterno del telaio 10 "), le proprietà sopra ricordano quelle del woofer da 11" della serie AR3. Il woofer Cizek aveva persino un anello di schiuma attorno alla superficie del cono a circa 2 pollici dal tappo antipolvere.

Qts 0,025 ????
