Dual center channels?

I bought my Axioms back in september, I've been happy with their sound quality except for the VP150. I've noticed that it lacks a certain theatrical quality. No matter what I've tried it can't really stand with the M60's. I've tried raising the volume on the reciever and sitting closer to the screen but I haven't noticed an improvement.
I noticed on the specs that the VP150 has high wattage output. I believe something like 400W. Would the VP150 sound better if I were to get another amp to power it? I know Audioholics even recommended dual 150's. What are your thoughts on this? Would dual center channels remedy my problem? Or simply more power? Or even a higher end center channel from another company? I would gladly spend the extra money if dual center channels would provide a significant upgrade, considering I primarily watch movies.

my setup: Vp150, 2 M60's, 2 QS8's, 2 M2's -- Yamaha V2600

Where is your center channel located? What amplification is driving it (and what is driving the M60s)? Do you frequently have the volume turned up pretty high? Is your surround system calibrated?

Dual center channels can be one solution, but there may be a way to get your existing one working as you like. I could be wrong, but I'd guess from a perfectionist viewpoint, trying to synch two center channel speakers (assuming different locations) can be a chore, and could potentially muddy the waters if not done right (this is not something I have experience with, so this assumption may be incorrect... I'm going on what I know of acoustics, time alignment of speakers, and the like).

My center is located directly above my tv, around 5 feet from the ground, and about 9 feet from the couch. Its being driven by my Yamaha V2600(as are the M60's).

Since I have no room to place it anywhere else(such as below the TV), my idea was to place the second VP150 right next to the other on top of the TV, creating a more robust left to right sound field and perhaps a bigger more theatrical sound(I assume, I could be very wrong, I am no expert).

I would love some more input on this subject. I'm beginning to like the idea of having a second center channel. Does anyone have any experience in this? How does one go about doing this effectively? Can anyone recommend a good amplifier that doesn't hurt the wallet too much? My logic, which may be flawed, is that with so much sound coming through the center channel during movies, it should be the best part of the home theater. And I just haven't gotten that so far from my lone VP150.

In most dual center installations I've seen, the second is set below the screen. I have a feeling that putting a second one alongside the first will do you no good--not to mention that would be one huge center!

Have you tried repositioning the center at all? Doorstops under the front? Even flipping it over so that it faces the ceiling?

Maybe try tweaking the receivers distance setting to the center. I found that after the initial setup of my system- changing the center distance by .5 feet up or down made a noticable difference in what I was hearing in dialog "presence". Experiment just a little (if you haven't) and select what sounds the most pleasing.

That's something I never think of. Could have something to do with it, though!

I saw that you have no room under the tv, but when I moved mine to below my TV in front on a separate stand it really improved.

I second that, especially with Yamaha receivers... I'm not sure exactly what goes on in there but the "half" settings sound radically different than the "whole" settings... almost sounds like they flip phase (they don't of course, but that's kind of what it sounds like)

I listen to 2-channel television in Neo6:Cinema, which puts a lot of the front info through the 150 and it works admirably.

Also, maybe check your settings for Center Image/Center Width on any of the DSPs that sound worse than others... maybe you've got the workload for the center set fairly narrow.

And of course, check that all drivers in the 150 are working.

A stand? Where can I find one for the VP150? I have a 52 inch toshiba, so keep in mind that the stand has to be short enough not to block the picture, and preferably be adjustable. Can anybody recommend a few options. Also, can someone please recommend a good amplifier to power both centers?

One last thing...Can someone PLEASE tell me if a center channel from another company would help? Something higher end?

After exhausting all the ideas here... maybe trying JohnK's vertical M22(s) as a centre might help?
