2.0 or 3.0 or 4.0 for HT Movie Audio?

For my home theater set up, I ditched the center a long time ago and have never looked back. With good left and rigth speakers near the TV, I don't miss it. My understanding is that if I had people sitting very far to one side of the TV or the other it might be a problem with uncentered images etc. But that's not an issue for us. The "phantom" center that most pre/pros or receivers genereate is really quite fine IMHO. There is a separate thread on this. Many agreed.

I do have surrounds and a sub, and think they are quite important to enjoying movies fully. Sub adds significant bass impact for LFE and generally for dynamic parts of movies with lots of bass. Surrounds are very important to me for ambiance and the spacial references. So my system is 4.1 (L/R mains, surround rear L/R, and sub).

My main system is 5.1 using all Gallo Reference with an Earthquake sub. It sounds glorious. My bedroom system is 3.1 using Gallo Dues (L/R) with Paradigm Center and an Infinity Sub.

The main system absolutely rocks, the Gallos are *amazing* speakers. And my 60 inch Mitsu HDTV has a fabulous picture. The system is being driven with a Butler TDB-5150 Tube/MOSFET amp which is a stellar unit. The Pre-Pro is an Emotiva UMC-1, great unit for the price ($699).

The bedroom system is much more modest, using an Onkyo multi-channel receiver to drive the Gallos and the Paradigm. CD/DVD/BluRay via Oppo BDP-83. The TV is a 32 inch Vizio. Nonetheless, I get a lot of satisfaction from this system. Especially since I have only $1500 invested in it. It would be "nice" to have some surround speakers, but the room is small and I really don't do any critical listening there. For what I use it for, it suffices quite well...

Our system is 5.1, but 4.1 seems to work just as well. We project onto a 100" screen, and the voices seems to come from the speakers' respective locations with just the L/R mains. I think it's important to match the voicing of whatever speakers you do use. We use the same system for 2.1 and 5.1 music as well as HT, letting the source determine the number of speakers that receive input. Our sources are CD/SACD from a Sony XA5400ES, DVD & Blu-ray from a PS3-80, and DirecTV HD-DVR.

I think a well integrated sub is important for both music and HT. For one thing, it relieves the amps and speakers from LF duty, and it can be difficult to set up speakers for both imaging and LF response.

If you are sitting in the middle between your speakers, and the speakers aren't total garbage, then there is no reason to add in a center channel.

What is it doing for you? Dialog will already be anchored dead center for you.

If you have a bunch of off access viewers, then yes, a center channel would be good to anchor the dialog.

This is more a question for you. Do you care about surround? If so, go 4.0 and add in the surrounds. If not, go 2.0. If you sit off access, add in the center. If you like bass and want impact, add in a sub

I listen to 5.0 for most movies. Rarely do I turn the sub on as it is generally not required or forgit to turn on.
