Sub Woofer Questions

First An Update:Getting my gear is taking a little longer than expected and thanks to everyone that has helped me so far.

I have just realized I never read the Sub Woofer Stickies I totally forgot about them oops,but now that I have read some of them I have some questions about subs in general and also about the one I choose which is Klipsch 12” 650W Powered Sub Woofer Model:SUB-12

Note: I have not read the Cross Over Network Sticky Thread yet I will read that one later

Here Are The Questions

General Questions

1.In The Sticky I read there is some information about harmful electro magnetic fields how concerned should I be about that if I plan on using my HT a lot?

2.If my Room Layout allows me to do so should I go with two Klipsch 12” 650W Powered Sub Woofer Model:SUB-12 Sub Woofers to get more Bass?

3.Iknow you can connect an External Sub Amp to a Passive Sub can the same be done with powered ones like the one I chose?

4.If My Room Allows should I get 2 Klipsch Sub Woofers to get more bass and feel more rumbling in movies?

Questions About the Sub I have chosen

1.Since the beginning multiple Forum Members have told me to get a different Sub than I one I have chosen is the sub I chose bad is there something wrong with the model I have chosen?

2.Does the sub I chose have a phase switch?
