SVS PB12-Plus or SuperCube I

[Dust]

I recently purchased a Definitive Technologies SuperCube I sub. However, I still have a little over 3 weeks to return it if I'm not completely satisfied with it.

Due to size limitations (WAF) and budget, what do you think about returning the SuperCube and purchasing the SVS PB12-Plus?

Anyone hear these before?

I listen mostly to movies (80%) and music (20%). I do prefer accurate bass.

Comments? Suggestions?

Thanks!
