Hi-fi Sub parameters

[aleexman]

hi,

based on the manufacturer data I have been unable to design an enclosure with valid parameters, using winISD.

the manufacturer data is as follows:

-Thiele Small Parameters (measured with voice coils in parallel)
Power Handling: 300WRMS
Impedance: 4 ohms (dual voice coil)
Voice Coil Resistance: 1.7ohm
Vas: 79.450 Ltr
Qms: 3.238
Qes: 0.446
Qts: 0.392
Sensitivity: 88.152 dB/Wm
BL: 9.992 TM
Fo: 28.77 Hz
Sd: 514.72 sqCM
Weight: 8.5kg

Can anyone suggest an enclosure size? I have heard that a sealed enclosure in the realms of 58Litres is suitable but I would have prefered a vented design.

Cheers.
