Axiom Home Page Forums General Discussion Home Theater 2 speakers as center channel? Pros and Cons

Hello TomTuttle,

Hope you are well. You would be amazed at the change in sound between a receiver with bass management and one without. The upgrade would be well worth your while to consider over anything else.

Hello TomTuttle,

Hope you are well. Was just thinking, does that Denon 1804 have just large and small settings for the speakers, if so do you know if it sets the crossover at 100Hz like most with only small and large settings. If that is the case then you would not even benefit from a center that has response below 100, it is all going to the sub, assuming you have the center set to small.

The crossover is adjustable between 80, 100, and 120hz I believe. I leave my 884 on 80hz.

I have been planning my HT for about a year now and I"m convinced to give an M22 or dual M2 a try as a centre.

Here's some links I've found useful on the subject:

This article convinced me that a horizontal arrangement immediately introduces design challenges not encountered with a vertical speaker. After all if speakers were optimal configured horizontally why aren't all speakers made this way? [Purely for aesthetics ( which is OK if that's what you need)] For this reason I'm favoring an M22 as my centre.

My only dilema is a single M22 or dual M2's... Still trying to figure that one out? Any thoughts?

Before making your decision, you might read this, Why not more discussion of 2 speakers as virtual center channel?.

I have no opinion either way, I just thought this might spur further input, particularly from the more technically knowledgeable.

Thanks Ajax - I was getting ready to point people over to my cross post... Seems there are some valid reasos to not do this, and its not like this is an afterthought....jb

Hello all,

Hope you are all well. For more information on this topic visit my very long thread in the Advice From Axiom Owners forum Here.

Alan just stopped in and added his thoughts to the discussion, a good read for anyone interested in this topic.

...because one center channel looks so sexy

Jack, as my reply to Tony in his earlier "pros and cons" thread indicates, although "comb filtering" exists, in my view it should be dismissed as being a significant concern. As Ian said about two years ago in a reply and speaker designer Dick Pierce has also stated, in a live listening room reflections create comb filtering all over the place and any small additional amount from two separated speakers playing the same sound isn't significant.

In my own multi-channel(pre-Axiom)setup, I use a vertical center speaker just slightly bigger than an M2, which is the same as the mains. One is adequate in my experience and is the logical choice for a center speaker, as in my view the horizontally aligned center is a solution in search of a (significant)problem. Two should be fine, and the center image won't move out any farther than the speaker on that side as the listener moves to one side or the other.

Thanks John. Makes me feel better.
