please help me design compact sub

I am trying to build small and light subwoofer.It should be used under pair of Yamaha DXR 8 tops in mobile dj setup. www.yamahaproaudio.com/global/en/product...r/specifications.jsp

So far I have simmed 3 options in WinISD using12N630 ,but I am new to this and I dont really know what I am doing.I need someone experienced to have a look at it and correct my mistakes.I am not sure if I entered ts parameters right,and if the driver would survive in any of those cabs.

any thoughts appreciated

I noticed that you have put the figure in for sensitivity straight off the BMS spec sheet. The BMS figure is way out it is around 90-91db

Other than that you seem to have got the hang of it but remember my comments on SP.

There is no way with our laws of physics that you can build a driver like this with that sensitivity in the bass region. I wish it could be so, you would never need to use anything any bigger
