Re: Ellis Family Retirement HT: Go big or go home

As long as you're well covering the reflection points you'll be fine. I usually do them 2' or so off the floor assuming 4' tall panels.

I am serious... and don't call me Shirley.

Re: Ellis Family Retirement HT: Go big or go home

I just measured for the ceiling, and i have a max of 6 1/2" for the ceiling panels including the drop... If I go 4" that will allow me a max of 2 1/2" for mounting... Is that enough of a gap?

If that's all there is then it's all you can do. Still the 2.5" will help extend how low they will function well.

Question Re: Ellis Family Retirement HT: Go big or go home

I have installed 6 4" 2x4 panels (3 per side) on the side walls so far (first reflection points)... I installed them right next to each other (touching), and the room already sounds much better. When i built these I used up another bag of Roxul, and I noticed my bass is much fuller now where as before it seemed lacking in the bottom end and was much tighter. I am assuming that when I finally get the bass traps built the bass will lean out again... Am I correct?

I hope to get the ceiling ones installed this week. When I am doing the first reflection points for the ceiling... Do I center the panel on each front channels speaker and then pick my first reflection point? The reason I am asking this is... If I use 3 2' wide panels, I will have a gap of about 3 1/2' between each panel, or I could install 4 (but then none of them will line up with the speaker). If I install them (3) 90 degrees I would then have 4' long panels with less than 1 foot in between them, but would need at least 2 rows. I could install as many as 7 in a single row which would give me about 90% coverage on the ceiling for first reflection. What is the best way to do this, as I have about 16' of width to play with?

Re: Ellis Family Retirement HT: Go big or go home

Bass control will tighten the bass and help with it cancelling itself out.

Not sure what you mean about the reflections being over the main speakers? If the speakers are at approx ear level, then the reflection will be 1/2 way along the diagonal between each seat and the speaker.

Re: Ellis Family Retirement HT: Go big or go home

Whatever it takes to catch the reflection points you map. Definitely will not be directly in front of the left and right speakers.

With Horns... Won't the sound be going upward and outward... If so I would think the ceiling would have first reflection points for the full width of the room. Am I wrong?

Here is a link to the horns... http://www.jblpro.com/pub/obsolete/23606566.pdf

Question Re: Ellis Family Retirement HT: Go big or go home

What is the preferred method of hanging the ceiling panels... The ceiling has 2 layers of 5/8" drywall with Green-glue. I am worried about penetrating the ceiling, and I am not sure if I can find the hat channels since it is completely painted (if I miss a panel then I have an unwanted hole).
