Homemade Ceiling Traps:
Ok people, today we will build some homemade ceiling traps! I use these in my own personal listening room to great effect. What they do is kill the ceiling reflections that bounce off the wall from behind the speakers. The open end faces your speakers and the closed end your listening chair. How simple are they? Read on!
The first thing to do is run to Home Depot or Loews and buy some closet bi-fold doors. They run about $39.00 depending on the width you choose. I used ones that are 14" wide for each individual door section. You will also need some chain, "S" hooks and "Eye" hooks to hang everything. Figure what you will need and write it down, making a list. Don't forget that you will need a way to cut the chain to the desired lengths.
Get them home and remove all the door hardware since you will not use that. I have a drop ceiling with the grid work in my listening room. I measured everything so that the eye hooks would be installed in the grid work and the boards, and the "S" hooks would be used to hang the chains with. I first installed the eye hooks in the boards, one in each corner, and installed the same in the drop ceiling grid work. You can see the photo below...
As you can see, this is how I hung my boards. The short end is only one ey hook down and the long end is 8" down to the board using the chain. The angle will depend on how much head room you will require with your ceiling height.
If you have a drop ceiling grid, measure the center points of the grids you will be mounting to and them mark the same distances on the boards. All in all, it will take about two hours to finish and install.
I chose not to paint my panels since they looked nice the way they are. Otherwise, you can paint or stain them at will.
What happens is the sound bounces between the boards and the ceiling and just dies there... before it reaches your precious listening ears. This will increase the soundstage, depth and more! An option is to put absorbent material on the boards on the side facing the ceiling, to better absorb the soundwaves that get trapped there. I left mine in the rough, without any absorbent material.
Let me know how your turns out!
YOU OLD BAG!
Fill three storage bags with sand. Washed and dried sandbox sand works well. Seal the Ziploc when the air is out. This is important to make sure the bags don't have any air.
Place the sand bags on top of vibration sensitive gear. Do this for CD players, preamps, etc. Be sure not to cover any ventilation holes. We don't want smoke tonight, unless you have a good cigar!
You be the judge! It is a fast and easy tweak. You will be surprised!
