I have some GIK 242s that I have mounted on my ceiling above each of my listening positions. I was wondering if it might be better to take them down and mount them on the ceiling above my 3 front speakers. I'm thinking this would probably help with any reflections from the ceiling. However, before I go through the trouble and effort of doing that, I was wondering if that would be the right thing to do. My listening position is 9' away from my 3 main speakers. So, if anyone has any pass experience on this issue, I would love to hear your opinion(s). As usual, I do truly appreciate any and all responses. BTW, my HT is in my basement. The floor is concrete with carpet on top, and the ceiling is drywall.

Above the head helps to minimize height related modal issues that are very common in 7.5-8' ceilings. The reflections are more for focusing the soundstage and minimizing smearing of the verticals.

They're not an either/or thing - just different.

I the acoustic center of the speaker is within a few inches of your seated ear height, then 1/2 way between your seats and the speakers is the reflections. Stretch a string from each seat to center of each speaker. Go 1/2 down the string and then straight up.

Thanks for the responses.

Bryan, I am a little confused about how to carry out what you said. "Stretch a string from each seat to center of each speaker. Go 1/2 down the string and then straight up." I have one row with 4 seats, and I have 4 242s. So, do I stretch a string from each seat to the center of the LF, for example, then go half way the string and straight up? Next, do I go to my next seat and stretch a string from that seat to the center of the LF and then straight up again? I'm a little confused how that will work. Could you please explain in a little more detials.

I was just trying to help you visualize what to do. But, yes, what you're describing is correct. You'll have a point on the ceiling for each seat, from each speaker on the ceiling. I was just trying to clarify that it's the angular distance from your ears to each speaker center.

A tape measure works just fine too. I've seen guys get 2 laser pointers, set 1 straight up on the front edge of the speaker and 1 on a block in the seat pointing straight up. Use a tape between the 2 laser dots and mark the 1/2 way point.

Note: This all assumes that the acoustic center of the speaker is within 6" or so of the height of your ears when seated.
