Axiom Home Page Forums General Discussion Advice from Axiom Owners W22 instead of QS8 for rear 7.1 HT

I don't understand JohnK's affinity for vertical centers...

I think he likes matching speaker L/C/R. I thinks it sense.

Yes the only way to ensure a perfect match of left main, center, and right main is to use the exact same speaker in all 3 positions. I believe there are a few other reasons he prefers a vertical center, but I can't remember them at the moment.

I use a horizontal center and am completely happy with it. Would I claim it is a perfect match to my left and right mains? Nope. Do I notice any difference between it and my left and right mains? Nope!

Hi Ajax,

You stated:
"Yes the only way to ensure a perfect match of left main, center, and right main is to use the exact same speaker in all 3 positions."

I'd preface that comment with "In theory, the only way. . .etc."

But in reality, the vertical center that's identical to its two mates at the front will still be subject to all the vagaries of placement (boundaries, the TV screen, walls, etc.) that prevent any three identical speakers from sounding absolutely the same, at least using a pink-noise test signal, when they are in slightly different positions in the room. Noobies are often puzzled why their speakers sound different when fed a test signal like pink noise.

The real test is whether through experimentation with placement you can get the center and the two mains sounding enough alike that with movie soundtracks or music there are no tonal or timbral deviations that will distract you from enjoyment of the music or movie.

Regards,

Agreed! I KNEW I should have mentioned placement differences.

Interesting - I noticed a tonal shift over the weekend when doing a little maintenance tweaking using a pink noise signal. The left M60 sounded different than the right M60. The left speaker is about 1.5 feet from the left wall and abotu a foot from the subwoofer, whereas the right speaker is butted up next to a chaise lounge that partially covers the lowest woofer - there is no wall on the right side. The tonal shift was minimal, but noticeable nonetheless. Obviously, the pan from left to right, through the VP100 mounted at mid-m60 level exhibits some shift as well, but when playing "real" material, I don't notice any difference between the left and right speakers at all.

To add to the original poster's question - I think the In-wall speakers would be a great addition to a 7.1 system. The low profile means that the couch doesn't have to be as far from the back wall to get optimal performance. The downside, of course, is that you really can't aim the speakers by using a wall mount, like you coudl if using a direct firing M2 and the FMB.

You have a very nice RSC200!
<<Drivers: Vifa Ring Radiator tweeter, one custom 4" midrange and two custom 6.5" long-throw aluminum cone woofers >>

My center is below the tv. About the level of the lower mid on the 80s. Above the tv it would be 15 inches above the 80s.

Should I use a 2nd center above the tv to even out the balance?

Just noticed that Jack is sitting on top of a reeeeally nice EP500 and yet his profile says "former Axiom owner". Things that make you go hmmmmm?
