A dimension ratio of 1 : 1.618 : 0.618 provides
cancellation of resonating frequencies inside the
enclosure,
this dimension ratio is used to calculate the cabinet
dimensions.
If only Q_{ms} and Q_{es} are known,
press "Calculate Q_{ts}>" button to
calculate Q_{ts}
 Q_{ms} and Q_{es} are optional
 Diameter, f_{s}, Q_{ts} and
V_{as} must be entered


Dia : 
cm

Diameter across the speaker cone including half of the
conesuspension

f_{s} : 
Hz

Resonant frequency of the driver 
Q_{ms} : 

Q mechanical  needed
to
calculate Q_{ts} 
Q_{es} : 

Q electrical  needed
to
calculate Q_{ts} 
Q_{ts} : 
 Total Q of the driver

V_{as} : 
liters

Equivalent volume of compliance 


 Volume and port dimensions are recommended for optimum
performance
 Both (Volume and port dimensions) can be changed to calculate
performance specifications
for different size ports and enclosures
 Enter volume of internal driver and parts
 Calculate performance specifications before calculating port
dimensions

V_{dr} : 
liters

Volume of internal driver and parts 
V_{b} : 
liters

Desired volume for the enclosure  You may
change the enclosure volume
