Axiom Home Page Forums General Discussion Home Theater QS8 surrounds

with time passing, i'm more and more interested in getting QS8's for surrounds.

just looking at the photos of the standard T bracket that comes with the speakers does not tell me how it is fixed to the wall, and how the speaker is attached to the bracket; something i would like to know before i buy.

does anyone have an exploded view of the way to install that?

Hi J.B.,
The Power Bracket" is screwed to the wall with three (3) screws. On the back of the QS8v3 you have two (2) golden clips which slide down over the horizontal bar of the "T" of the "Power Bracket". The speaker wire can be directly connected to the binding posts of the QS8v3 spaker or it can be connected directly to the "Power Bracket".

Here is a link for the installation instructions - Online installation instructions

I didn't know the power bracket was available with the QS8's yet. I have the on-wall M22's and the power bracket makes it easy for one person to mount. I didn't care for the little plastic clips on the M22 that had to be pulled out of the way to unmount them though. One of these had broken off, but it doesn't affect the security of the mounting.

it seems from the fuzzy drawing in the document that the 3 screws are aligned vertically; is that right?

CatBrat,
The Axiom Power Bracket has been improved/modified since its introduction and the newer design does not have the tabs anymore.

J.B.,
That is correct. The top and bottom holes on the bracket are oval allowing slight adjustments for a perfect levelling.

thanks a lot JC.

you "sold" me. (wasn't that an easy sell!)

see you next month about buying the QS8's;
they'll be replacing my Energy 22 Ref.

Always a pleasure J.B. !
I'm looking forward to read your comments on the peformance of your Axiom QS8v3 !

oh, another question.

with the QS8's, is it better to install them at 90 degr. or more at the back, like at 110 degr. ?
would 110 degr. give a better rear soundfield than at 90 degr.?

they each would be about 5 ft. away from my ears, and the fronts
are 6 ft. from my ears.
the room is 9 ft. wide.

I recommend using toggle bolts to hold the bracket to the wall since not every whole will necessarily line up with a stud. Nothing like someone's QS8 dropping off the wall due to someone just screwing into drywall...

Or just dropping off the wall..

the old brackets were pretty flimsy, I used wall anchors as well.

i used these to install my QS8's into the celling since there were no studs where i wanted them to be, and changing the location would have been less than ideal.

Each anchor is rated for 79lbs, so they should have no problem holding the 13lb QS8...

But that rating is shear force (ie perpendicular to the drywall), not pulling force (ie OUT of the drywall). You need a toggle.

J.B., The optimal location depends of your room acoustics and your personal taste. As an example, Ian (The Ian) prefers his side surround QS8v3 surround speakers slightly ahead of main seating position.

Woah. That's where I was going to have to mount mine. I didn't know anybody actually preferred them there.

I had mine there in my old place. Didn't like it, but I also didn't have rear surrounds. I'd say those would be necessary if you were to mount them in front.

In my living room, I was going to mount the side surrounds about half way between seating position and tv, with 1 rear surround for a 6.1 setup.

quote JC: "J.B., The optimal location depends of your room acoustics and your personal taste. As an example, Ian (The Ian) prefers his side surround QS8v3 surround speakers slightly ahead of main seating position."

you mean "The Ian" uses Axiom speakers in his own home! ;-)

And here Dakkon thought he used WATT Puppies.

Jacques, in a 5.1 setup without back surround speakers, it's preferable to have the side surrounds slightly(maybe 2')farther back than directly to the side of the listening position. Although less significant with very wide dispersion units such as the QSs, it still helps in providing a "phantom" back surround effect on sounds about equal in level in the left and right surrounds. So yes, more like 110 degrees.

JK, this is what my logic was telling me, and that is most likely what i will do. thanks.

Yup the rating is in shear force, you are correct Ken. however, I also have a pair of speakers in my bedroom that are on brackets that i made that are hanging on the walls with these same anchors.. At a shear rating that is over 2X the weight of the speaker per anchor, the rating shouldn't be an issue, the surface area of these anchors is extremely high, and as you know the larger of an area you spread a load over the less force per given area.. drywall toggles have only 2 points of contact. However, i could not find a quick rating of drywall toggles but i suspect they are not going to be a lot higher than 75lbs, since drywall is the weak link here, not the anchors.

Of course i would expect Ian to have axiom speakers.. Why in the world would he have a pair of the competitors... If he did buy a pair of the competitors speakers i am sure he wouldn't get a pair of puny WATT puppies, i think he would have gotten a pair of WAMM's or Alexandria's....sheesh ken give Ian come credit man.....

Heh, just yanking your chain, dude.

i know, but you know that you should expect to get some right back brotha :~)

another question, hoping it's the last one:
for QS8 side surrounds, do you think it's best to mount them low, or a bit above the head or high on the side walls, and maybe tell me why?

J.B. i currently have my QS8's mounted on the celling about 2' or so behind the seating area. They are probably 4' above the seating area.

I think that this is a good location due to the spacial separation between your ears and the speakers. With the multi driver design, i have noticed in this set up that the sound "envelopes" you more than having the speakers closer to the listener. Again, i have had 4 different setups, many of them were severely space limited (military barracks living). The last place i lived (an apartment) i was using the stands, and the speakers were at ear level when sitting, and directly to the left and right of the respective seats. I did not like that setup as much as my current one because the speakers were only a couple feet away from your ears, and the effects/sound was not as enveloping due to the closeness of the speaker to the listener. i would say my current distance head to speaker is about 6-8' from my chair. more to the left and right than behind, if i had the room i would prefer them to be about 2-3' farther back than they currently are.

I hope this helps you in your decision, i have tried to be as precise with my reasoning as possible.

I have had my 8s at 7.5' from the ground and now are at 60"; I like the 60" position much better.

Jacques, a common suggestion for the indirect nature of most surround material is to position the speakers about 2-3' above ear level.

Question on the new bracket. I currently have a older pair of QS4's that I'm going to be using as side surrounds (5.1) but in the future my plan was to replace them with QS8's and move the QS4's to the rear (7.1).

My initial thought was I wouldn't even have to move the brackets but now that the v3's have this new one do I need to worry about the holes left from the old bracket when installing the new one?
