INTRODUCTION
Congratulations! You now own the best acoustic
diffuser on the market today! There is no better back wall for
your control room, no better treatment for your home theater,
studio or performance space.
The Acoustic Ramp™ is most effective when used in
an array of 2 or more Ramps. The wedge shape of the diffuser
allows the installer to direct reflections away from the sound
source to prevent the mal-effects of comb filtering in the
listening position.
If you are a genius and you never read instructions, you
certainly don't need to read the directions to assemble your
Acoustic Ramp™.
However, if you don't have an offset screwdriver we
STRONGLY RECOMMEND that you read and follow the
directions to avoid the frustration of not being able to fit your
screwdriver between the dividers. We spent a lot of time
figuring out the easiest, fastest way to assemble the Acoustic
Ramp™ with the fewest possible tools.
Please do let us know if you have found an easier way,
we would love to know about it!

- Page 7 Step 1. Layout all the parts and hardware Why Are the Parts Named Like They Are? Assembly begins with the front of the Ramp facing down, so The Dividers are Labeled you will be looking at the REAR of the ramp. This means that you should be able to see all of the stickers that label each one of the pieces D (Divider) - Well Depth in Units - Left or Right Side clearly.
- Page 8 Ramp is Upside Down Step 2. Using the 3 3½” flat head machine screws, join Divider D-2L to Reflector R-2L, the center Divider D-C and Reflector R-2R. Reflectors R-2L and Divider D-C have unthreaded holes to allow the screw to pass freely. Reflector R-2R has a threaded insert. We found that it was easiest to push the screws through the D- 2L divider first and then lay the divider down so that the screws point up.
- Page 9 Step 3. Using 3 flat head ¾” machine screws attach Divider D-2R to the assembly as shown.
- Page 10 Step 4. Attach Reflectors R-4L and R-4R to the assembly with 6 Pan Head ¾” machine screws as shown. Now that these “wings” are attached you will begin to assemble the two sides of the ramp. If you are planning on using the included Wall Hanger Hardware, you can install the Wall Hanger Clip at this time (see Mounting Instruction on p.
- Page 11 Step 5 Now that the Center Section of the Ramp is assembled, you will begin to assemble the two sides. Using 3 Flat Head ¾” machine screws attach Divider D-4L to Reflector R-1L as shown. Repeat with 3 additional Flat Head ¾” machine screws and attach Divider D-4R to Reflector R-1R as shown.
- Page 12 Step 6 Using 3 Pan Head ¾” machine screws for each side attach Divider D-1L to the left side assembly and attach Divider D-1R to the Right Assembly. The D-1 Dividers are the smallest divider pieces in the kit. If you are assembling the Ramp with the Rear of the Ramp facing up, the left and right sides are reversed.
- Page 13 Step 7 Flip the Side Assemblies over so that the Rear faces down. Using 3 flat head ¾” machine screws for each side, attach Reflector R-ØL to the Left Assembly and attach Reflector R-ØR to the Right Assembly.
- Page 14 Step 8 Flip the Right and Left Assemblies over and position them to either side of the Center Assembly as shown. Using 3 pan head ¾” machine screws to attach the Left Assembly to the left side of the Center Assembly, which will be on the right because the Ramp is facing down.
- Page 15 Step 9 Using 4 ¾" flat head screws for each side, attach the Left Side Divider to the Left Side of the Ramp. Attach the Right Side Divider to the Right Side of the Ramp. Again the sides are reversed because the Ramp is facing down.
- Page 16 Step 10 Turn the entire assembly over length-wise so that the front of the Ramp is facing up. Fit the Top Plate into position. The dividers should extend beyond the front face of the top plate by ¼”. Using two ¾"flat head machine screws for each side, attach the top plate to the rest of the assembly.

Page 17: Mounting Instructions
The basic installation of the Acoustic Ramp is in a vertical position with deepest part of the Ramp on the top (see Fig. 1). This type of installation is not permanent and does not require any modification to the Acoustic Ramp™. - Page 18 Measure the width of the wall in question and mark the center point on the horizontal line you have already drawn. You will center the Acoustic Ramp or Array of Ramps based on this point. Figure 3 Full View of Wall Hanger Clip Assembly...
- Page 19 There are many other ways to install and configure the Concrete and Masonry For installation into concrete, CMU or brick walls use either Acoustic Ramp. Please visit our website for ideas and instructions. expanding concrete anchors or pre-drill holes for threaded concrete fasteners.
- Page 20 Permanent Professional Installation The Acoustic Ramp™ may be installed in any orientation to obtain the desired acoustic and aesthetic results. The included Wall Hanger Hook and Clip assembly are intended for non-permanent installations in the vertical orientation only. The Acoustic Ramp may be installed permanently by drilling holes through R-4R and R-4L and mounting the Ramp directly on a wall or ceiling.
