Dual Centers

Has anybody had dual centers?
If so, where did you place the second one and what's your experience?

Also, why did you do that?

Generally a bad idea. Comb filtering and phasing are usually problems.

I have seem them on a large projector/screen setup (100" plus I would guess) with one just above and one just below and it sounded nice. It seemed work well with such a large screen as the sound seemed to be coming from the center of the screen.

Proximity to each other influences the comb filtering. I'm running 2 JBL LC2 centers behind my 106" screen. 1 is below the screen, the other is 2/3 the way up the screen. They are also angled slightly away from each other.

I gave it a hard listen before and after doing this setup. I did not notice any comb filtering. What I did notice was a much wider sound field than running a single center channel.

Another way of accomplishing the wider sound field would be to use a single tower identical (or similar) to the left and right for the center.

I personally like it.

I have a second row of seats and this has a center directed at each row.

I'm not encouraging this and I don't know what would happen if you had 2 different center channel speakers. Mine are identical.

That being said, I have recently got the hookup on a single JBL L880, and plan to swap out the 2 LC2 (pictured) for the single L880 tower and see how I like it.

One of the best things about having a home theater is being able to experiment with things/ways that give YOU the best experience.Click image for larger version

If I get dual centers, they will definitely be identical.
