Jon Risch DIY acoustic panels have changed more than any other system, modify and upgrade components. After inserting the disks heard in my listening room early and diffraction reflection points (two behind the speakers and four side walls (the two panels, the closest to me actually sitting in chairs, because they did not move, the chairs out of the way)) I these improvements. From that first listening session I have had mixed results from CDs played in my Pioneer DV-47ai and TaddeoDigital Antidote II: certain frequencies and instruments must be relaxed. Thaddeus take out and see if I can play the same high performance as AirTunes from my MAX ripped Apple Lossless tracks get.
Read on for my tips and tricks to build these plates themselves and save up to 90% on the commercial acoustic panels.
Materials 6 17 × 48 inch acoustic panels need:
* Home Store: R-25 insulation 24 feet (15 cm wide and 8 mm thick)
* Home Store: 16 4 m long1 x 4 hours Boards
* Home Store: # 8 2-inch screws (I bought the kind of boring so I had just sunk drill pilot holes in the tips of long frame boards for shorter cracks worms)
* Home Store: 9 / 16 Staples (requires long period to get through the many layers of tissue and cells)
* Fabric Store: 10 meters of polyester batting 4 oz 100%
* Fabric Store: 10 meters of cloth (you can help your spouse to choose the color, then I can not complainlater)
Tools needed:
* Electric drill / driver
* Corner Vise (spend at least $ 8 to $ 3 when there is combustion of wood, which cost me another trip home contact shop)
* Staple Gun (You are like a madman on this specific project to be sure and get a good seamstress, killed my Black and Decker Powershot half way through the project and had to buy is not new, still cause jams paper, so with a power stroke, have a beautiful gun, arrow)
* Miter handSaw
Construction
Wooden structure
* Match 4 ft. studs for length in 6 pairs
* Take 4 worst studs and cut into 12 x 15 cm in length with a miter hand saw (or saw), make 90 degree cuts
* Take a small piece of 1 × 4 and the depth mark at both ends of the uprights 4 ft.
* Drill pilot holes at each end of two sunken in the middle of the area marked off on the cards long-
* With a 90 degree corner vice, butt, short and long post. Drill screws through 'Pilot holes into retirement soon. Repeat for the other pair of long and short. Now you have two "L" shapes.
* Replace the two "L" 's only in the previous step, such as a rectangle 17 mm x 48 mm x 4 cm, depth form.
Fasten Insulation to Frames
* With all the pictures that he saw two horses (or storage boxes like I improvised), in an area where you can easily cut and clean the glass fiber (such as your garage) with
* Measure the inside length of the first frame, should be about46 is a function of the precision of 1 × 48 inches long by 4.
* On your equipment fiberglass insulation protection (mine includes a respirator, gloves and Tyvek coverall in suede (sweaty)) put
* Sometimes you unroll your insulation on a cutting surface (like the garage floor cement) and measures a length of 46 inches (or whatever it was inside the length of the previous frame time)
* Lay the picture on the horses saw horses with a quarter in length from each end
* Withthe kraft face side up, press the insulation into the frame. Staple the paper strips to the frame, securing the insulation.
* Set first frame aside and repeat for the rest.
Wrap frame in Polyester Batting
* Roll out your polyester batting on the same cutting surface as the insulation (you should have this all cleaned up now)
* Measure the length and add it to depth of either end of the frame including the insulation thickness. I decided to cut the lengths of my batting at 60 in. lengths (frame = 48 in. length + 2 x 6 in. depth) and keep the width to 48 in.
* Set the frame on the saw horses facing up (the kraft side of the insulation on the opposite side)
* Lay the polyester batting on top of the frame. Get the length as even as you can while positioning the batting along the width so the side closest to you hangs down about an inch below the frame, the opposite side should be hanging down by 24 in.
* Tuck the the short side batting between the bottom of the frame and the saw horses and flip the frame toward you so the 24 inch side falls across the kraft side of the frame.
* Staple along back frame
* Cut away excess batting and staple ends after folding like wrapping paper
* Make sure no insulation is exposed, the batting should completely encase the front, back, sides, top and bottom of entire framed fiberglass panel.
Wrap Frames in Burlap
* Wrapping the frames in burlap is just like the polyester batting with some tricks
* Cut the burlap to 60 in. lengths (another how to suggests starting a cut in the burlap and then pulling a loose string from the cut to create a straight line to cut along. This didn't work for me, pulling the string would bunch up the fabric and then snap, at best I would get a straight line across half the cut)
* Lay the fabric over the panel unevenly and flip, wrapping the fabric around the back as described above with the polyester batting
* Pulling the burlap snug staple the long sides to the back of the wood frame
* Fold and staple the burlap to the bottom end of the frame like you're wrapping a present
* Take off saw horses and give open top end a tug to pull front of fabric tight until wrinkles disappear. Cut away excess fabric and staple.
* Finish with fabric border to cover up staples
Place Frames at Early Reflection Points in your Listening Room
* While sitting in your sweet spot have a friend move a small mirror along your front and side walls. Have your friend mark the points along the walls that you can see the speaker drivers for the side walls and the inside corners of the loudspeakers on the front wall (or if you're like me and couldn't bring yourself to ask your eight month pregnant wife to slowly walk around with a mirror and tape you can use a CAD application or this formula and verify the calculated locations with a mirror taped to the wall in the approximate place)
* Place the panels at the mirror points (I'm just leaning mine against the wall at an angle so they don't fall over, I'm not attaching the panels because I need to move them out of the room when not in use), bass absorption is improved by placing the panels at least four inches out from the wall
* Listen and enjoy!
