A stronger subwoofer?

[RadeonMaster]

Hi guys, so I was thinking of upgrading my subwoofer but i don't know exactly which of these two is better?
We have:
"Magnat Stylus 7000 A" https/www.kupujemprodajem.com/Magnat-Stylus-7000-A-42555489-oglas.htm

and

This one which i don't know the full name https/www.kupujemprodajem.com/Heco-43517014-oglas.htm

Lets ignore the price and age of these two and just focus on power and bass strength.
Which of these two is better?

the ported front firing one looks like it would sound better.
