I thought I would throw this one out there, after reading several posts on the 'phantom' centre thread. A number of you guys have chosen to use two centre channels so I was wondering what made you decide to go this route and what are your conclusions are so far, in retrospect vs a single centre speaker?

If you have a large screen, a single center channel can make the dialog sound like it's coming from the edge of the screen instead of from the middle. Two center channels, located above and below, will fix that problem.

I have played with this idea for a while, since I have a six channel amp in a 5.1 system. I have a 130" plus screen and really don't notice the sound not comming from the screen.

The cool thing about the VP150 is it's tappered. So I got great results by putting the 150 up side down. This angles the drivers up towards the listening positions.

However, there are other people here that have two center speakers and are very happy with the results. Some even have gone with a VP100 and VP150 combo.

I think that is cool.

Also, keep in mind Adrian that if you have two 6ohm center channel speakers in parrallel, you will then have a 3ohm load on the receiver.

Sirquack is very correct here. You better be armed with the right hardware to do this. Your reciever should have an extra channel that is not being used. Or, if you are using a separate processor, it should have inputs for 2 center channel speakers (like my Rotel RSP1066). I don't like to "splice" in my HT setup. Very bad things can happen!

I was asking more out of curiousity as to the benefits of such an arrangement but it's not for me for two reasons, well three maybe, I only have a 52" screen, dropping to 3 ohms is quite likely an issue and I simply wouldn't need the second centre. I see that Axiom does in fact have double centres in a couple of their HT packages. If I had a 130 inch screen, maybe. I've seen some HT's on here where guys have chosen two vs one centre, so I was more curious than anything.

I have two M2s hooked up in series as centers. I did a lot of reading on center channels and learned that the best speaker configuration for any speaker, including the center is vertically aligned speakers. It gives better off axis performance. I think it also does a better job of centering the dialog on the screen, or at least makes it a lot easier to do so.

For the price of a center, 2 M2s seemed like a good idea. Seems to work just fine.

P.S. having a vertical center over your display is good for extra manpoints as well. ;\)

Fred, what kind of ohmage would you be dealing with going with the 2 M2s ? how many manpoints is an M80 centre worth?

Two 8ohm speakers (M2's) in parallel is a 4 ohm load. No different than having an M80 on a channel. Don't know how many man points an M80 would be.

Fred, You got any pics of that setup?

6 ohms because its in series. If I hooked them up in parallel it would be 3 ohms.
Edit: Bob is correct. For some reason I thought that the M2 was 6 ohms.

If its upside down over your display it gets you an instant mancard platinum.
