CDT has sent me the following on their HD subwoofer line:
FS=30Hz
Vas=26L
X-max=20mm
X-mec=30mm
P-Dia=201.9mm
Sd=320 sq.cm
P-Vd=0.64Litres

Is P-Vd the recommended box volume? They didn't even specify if it should be sealed or ported. [img]graemlins/dunno.gif[/img]

do you want sealed or ported? I'll pop it into winisd for you if you'd like.

You don't have enuf information - you need at least Qts but it's nice to get Qes and Qms too [img]smile.gif[/img]

Sealed please. [img]smile.gif[/img] I need this box as small as possible. I knew there is a program out there for this.. do you need more specs? I have them but they are all "chinese" to me.. [img]tongue.gif[/img]

Qes=0.44
Re=0.95ohm
Bl=8tm
Pe=600W

Qts=0.417
No=0.154%

Thanks.
