Is a Sub required for HT

I purchased an SVS PB 2000 today...no complaints!

Great choice.

Love my SB13 Plus

I watched the Jungle Book last night and the SVS  PB- 2000 did exactly what I wanted. In a HT context it offers very, very good value.

I like a sub in my HT system for movie effects but I don't like a sub in my 2 channels system with full range speakers.

Subs aren't required for HT.  You will get better bass performance with one and movies, particularly one that involve a lot of explosions, will have more umph.
  If your front speakers are capable of going low enough-a rare but not impossible event-- then you won't miss that much
