You know the average sheet of paper is quite close to the height.width of a QS8? Yes I have paper taped to the walls in possible locations.

As long as the placement of the back surrounds is wide enough so that all listeners can hear both a left back and right back effect, the result should be satisfactory.

About 4' above ear level is within the recommended range for surrounds, but shouldn't be raised farther.

With back surrounds being used, the side surrounds should be directly to the sides of the listening position, since positioning them farther back isn't needed to help with a rear surround effect.

Enjoy the music, not the equipment.

So Brent was kind enough to see I had a question here and reached out to me in email. Unfortunately my schedule is not allowing me to call right now.

I typed up the questions in email. % points I am looking for guidance on. 4 are pretty much givens. Just need to know if its acceptable.
The 5 is a 4 option choice.

Here it is:

Want to bounce some things off someone there as well as get a recommendation on front L R height placement.

Looking at I/O 22, I/O 150 and QS8s


Putting in Front L C F
Putting in LS and RS
Putting in LR and RR

Room is roughly 22’ wide by 16’2” deep. Ceiling goes from 8’ to 12 ‘ front to back.
Listening area is 11’ back from the front wall.

Starting with the side surrounds:
The bottoms of them are at 95 ½” from the floor
The listening height is 46”
The right is at 93* to listening point, left is at 91* to listening point.
I cannot decrease the height of these unless I position them forward of the listening point.
The speakers at this height have roughly 27” above them, so they are not hugging the ceiling.
Does this all sound acceptable for the sides?

Now to rears:
The bottoms of them are at 95 ½” from the floor
The listening height is 46”
The speakers at this height have roughly 41” above them, so they are not hugging the ceiling.

For the RR, the right (outside) edge is 52 ¾” from the side wall, resulting in 133* to the listening point.

For the LR, the left (outside) edge is 58” from the virtual side wall, resulting in 144* to the listening point.
Does this sound acceptable?

Now for the front.
The center line of the center speaker is 52 ½” from the floor.
Listening height is still 46”
Center of the display (a 52”) is at 71 1’2” from the floor.
These I really cannot change.
Does this sound acceptable?

The question here lies in the L and R.
I cannot change their horizontal location. The vertical centerline of both will each be 21 ½” from the centerline of the viewing center.
This results in 14* for each one.
Does this sound acceptable?

The question is about their height.

Choices:
1. Position in a normal manner so that the L & R tweeters are in a horizontal line with the centers tweeters. (This positions the L & R lowest in relation to the display)

2. Position in a normal manner so that the L & R centerlines are in a horizontal line with the centers tweeters. (This positions the L & R closer in relation to the display)

3. Position in a normal manner so that the L & R bottoms are in horizontal line with the bottom of the center. (This positions the L & R closet in relation to the display but offsets the tweeters the most)

4. Position in an inverted manner (tweeter on bottom) so that the L & R bottoms are in horizontal line with the bottom of the center. (This positions the L & R closet in relation to the display AND the tweeters are horizontally aligned)

What would be your choice and why?

So 5 points that I am curious about.

Order is placed. Glad I delayed as I was able to take advantage of the 20% on In/On Walls.

What was ordered:
2 I/O wall 22s in white with white grills
1 I/O wall 150 in white with white grill
4 QS8s in paintable finish with warm tan grills (the grills may be a close enoungh match that I do not have to paint them)

All said 10 days to ship. Thats fine. I have a lot of work to do before we get to mounting them

Once mounted I will post pics. The WAF should be quite high on this one.
