Hello BigWill,

Hope you are well. Although I don't have a camera, I measured everything and drafted a schematic drawing of the setup. All proportions on the original drawing were at 1/8th scale, so all the proportions are correct. Hope this helps.



Later,

TonyM

Ah, jeez, you didn't need to go and make a drawing! Thanks though, I see that it actually has a nice symmetrical look to it there.

Hello BigWill,

Hope you are well. No problem making up the drawing, I figured it would give a decent representation of how it looks, with the added benefit of the actual dimensions that a picture would not give.

Hello TonyM,

Interesting thread you started. I just chatted with Ian Colquhoun, Axiom's designer and founder, about this subject and we both concluded that there really are no downsides to using a pair of M2i's in parallel as a center channel.

In theory, you would get some constructive and destructive interference across the spectrum, but we already deal with that with no problems from two main stereo speakers in stereo or a 5.1-channel surround system.

You would definitely get better dispersion running two 8 ohm M2i's in parallel, and apart from the lowered impedance to 4 ohms, would be almost like a VP-150.

There is a decided advantage to using two centers, particularly if you have one of the newer large-screen rear-projection sets that offer no flat surface above the screen on which to put a center channel. My own option may be to use a pair of M2i's, one on each side of the set so that the dialog images in the center. Putting one in front is not an option because it blocks the infrared remote sensor of the Samsung DLP. I'll report on the results of A/B tests I'll conduct with two M2i's vs. one vs. a VP100 or VP150.

Regards,

Hello Alan,

Hope you are well. Thank you for stopping by and posting your thoughts, it is highly appreciated. A/B testing would be fantastic, since I can't do it on my own, and would really like to know the truth. I seem to have created a monster with this thread, many other threads have popped up on the forums with people asking questions on this topic. So, any input you could add to answer all the questions generated would be appreciated.

Thank You,

TonyM

Hey Alan,

If you're not too busy, would you please take a look at this short thread. These fellows are presenting arguments why the 2 M2is used as a center would NOT be a good idea, and I'd like your take on their ideas.

I would think using 2 M2s side by side but angled away from each other would provide wide dispersal. But, my knowledge of the physics involved wouldn't fill a thimble. So, for heaven's sake, don't pay any attention to me.

I am really interested to hear your results on this.

As I now have QS4s and M50s (thanks, Sutter!), I have noticed the lack of a center channel more. The WAF is very low for a horizontal center on top of the TV, so I've (please don't hurt me!) piped the center channel preout of the 525 to the TV speakers. It's certainly anchored to the screen, but the sound is a bit... lacking. So I'm going to try using the satellites from my old CSW Ensemble 1 set as a pair of centers on either side of the TV. I did a little graph of the impedence, and concluded as long as the 525 can handle a 4 ohm load (which it can), I should be fine no matter what the impedance of the sats is (the sat+sub combo is rated as 6 ohms).

I tried to keep away, but I couldn't!

Well, cancel that. The CSWs are extremely poorly shielded (ie, not at all). Grr...
