Totem Storm sub vs PSB HD10 ?


I have a Celeste PW4000 integrated amp with Totem Rock speakers and of course I am missing something. What do you think, shoul I go with a Totem Storm sub or a PSB HD10 ?

I'm very happy with two Storms paired with Forests
One would be great with your smaller Totems
Thanks !
I have the Storm that I have integrated with Celestion SL6si's. It works great for me.
Totem Thunder will outperform both. The storm is ok but never satisfy me like the way the Thunder did.
I have one Thunder sub that ready to go up on audiogon. If you interesting, let me know.
