Question Single center channel, or twin bookshelf speakers in the same position?

Which would be better, a single center channel, or twin bookshelf speakers in the same position.

In terms of drivers, they would have the same number of 5 1/4" woofers, but the number of 1" tweeters with the twin bookshelves, would increase by 1.

In terms of price, it's a $25 increase for the bookshelves.

In terms of Impedance, the center channel is a 6 ohms and the bookshelves are 8 ohms.

Am I wrong in thinking that the twin bookshelves would be better at spreading the sound across the center position?

Better chance that they'll end up cancelling each other out unless you plan to have them fire out of phase. How are you planning on powering them? I hope you're not going to just wire them together and hook 'em up to a receiver. The impedence change'll probably fry something. Unless you're running a separate amp you're better off with just the single center.

Just do a single center.

It's possible - that's why I was looking for some feedback.

That is where I was eventually going to go with this question, as I didn't know if wiring in parallel or series would be of any use in this situation.

I was a bit concerned about that, as I just found the thread about center speakers being better in the vertical position, and the center speaker that I was planning on, would have been absurdly high ( intruding into TV area ), if I stood on end. so I was looking at alternative ideas.

Your best bet is 3 matching speakers placed in their proper orientation (vertical) across the front. If you can't accommodate this type of setup, then you should probably do like the rest of us and use a dedicated center channel and leave it in its proper orientation (horizontal).

I have a pair of bookshelves as centers. I was hesitant at first aswell, but doubt i'll go back to a purpose built center.

I tried it for various reasons, no place to position a dedicated center, couldn't find a polk center at the time with enough presence, a fellow forum member was doing it and suggested it.

I do run them in parallel, so the amp sees half the original impedance. In doing this you also need to dial back the level of the center, (mines at -4db). You need to be sure your AVR can cope with a 4ohm load before doing it, our denons have no problems.

If you can try it without buying anything i suggest you try it and see if you like them as centers...

The question to me then "What is proper orientation for the center channel?"

This thread says that while horizontal may be the so called "proper orientation", better performance is obtained when it is vertically oriented.

Horizontal Center Channel Speakers and Why They Should Be Avoided
A vertical MTM center speaker will perform better than a horizontal MTM speaker in almost all cases. In tests done by Audioholics, when horizontally oriented dedicated center speakers were positioned vertically, they performed better. Surprisingly, a bookshelf speaker performed better than most horizontally oriented center speakers.

Your best bet is to use a single vertical bookshelf speaker that is timbre matched with your front speakers. If you want to use two center speakers, it will be better if you connect them to two power sources. Also, it is important to experiment with their position and perhaps wire them out of phase to lessen any chance of wave cancellations.
