Question Regarding Using Two Subs In HT


Hi all. Have decided to go with two subs in our HT set up. Is it essential that they be exactly the same? We just bought a Def Tech 600 package. And now I have an extra sub. It's an Energy Take Five.  Thought I could save money if I could get away with it.

The more subs the better. No they don't have to be the same at all. More subs gives smoother, faster, better bass. 
Definitely do not have to be the same.  A little more difficult to get it "right" but most times very doable.   I should know, I am/was using 5 subs, twin Klipsch RT-10ds, one Klipsch RSW-10d, one SVS-SB13 Plus, and one Revel B-15.  Lots of trial and error.
