Has anyone ever tried two center channel speakers?

Sorry to say this but:
1. Putting a speaker on its side will leave you subject to lobing and poor dispersion.
2. Adding another next to it will make all that worse.

Use one center speaker standing up or, depending on your setup, a center speaker with correct driver orientation and spacing.

There are many good reasons why the vast majority of quality speakers have their drivers arrayed vertically. Conversely, the vast majority of so-called dedicated center channel speakers are awful, having been designed to accommodate naive expectations and esthetic requirements at the expense of audio performance.

Normally designers try to align vertically the tweeter and mid range for good reasons - you should really use your speakers the way they were intended (vertical)

I'd never heard of lobing before this thread. I've used the speaker in this orientation for over a year with very good results. I had an Infinity Kappa home theater center speaker, it is an excellent speaker for a conventional sized room, it was just too small for my room. I happened to have an extra pair of Kappa 7.1's in storage....pulled one out and plunked it down and 'voila'. Now I've got myself a serious full range center channel. Standing the speaker up vertically is not a consideration and out of the question. It is just too big and tall.

Thanks for the input. I did a search for lobing in the forums here and found a lot of good info, explanations and opinions about it.

Since I have the extra amp and speaker and a huge room, I'll give it a shot anyway and see what happens. If it doesn't fly, I'll go back to business as usual.

....thanks again guys, I love this forum.

I had 2 pairs of PSB Alpha A/V's that I used for my home theater system. Since I had an extra speaker after using one for each L/R/C, I tried putting two speakers in the center channel area. Oriented horizontally, with the tweeters out, it sounded much better than a single speaker. So much so that I opened the backs, bolted them together from the inside, and screwed the backplates back on. I then got another pair so that I could stack the L + R speakers as well, because I found it to be such an improvement.

I realize this runs contrary to what people have said thus far on this thread, but I experimented and found that it worked great. 6 years later, this is still my center channel speaker.

I once had two right channel speakers to the same effect.
