![]() In this example a 50/50 cotton/acrylic felt, 3 mm thick is used. Ideally you will want to use a nice thick material that will effectively absorb sound waves. This is to limit the reflection of sound waves in the enclsoure. It is always a good idea to cover the magnet with sound absorbant material. Use Sound Absorbing Material on Large Reflective Surfaces Photograph 3: Rubber Cement / Adhesive used to hold Felt on FE103En. Photograph 2: Use Duct seal putty to fill gap between speaker motor and chassis. Check the improvement for yourself by tapping the speaker chassis with a screw-driver before and after the modifications and listen to how much quicker the chassis ringing fades away. Photograph 2 shows an example of using duct seal to dampen the open gap between the motor and the chassis. Electrical duct seal is a non-hardening sealant that adheres to metal, masonry, wood or plastic. ![]() You should be able to find the duct seal in the electrical section of your hardware store and a block should be under $5 (Photograph 1). The duct seal will help dampen against ringing. Fill Gap between Chassis and Motor with Duct Seal Puttyįill the open gap between the motor (magnet) and the chassis (frame) using duct seal. For the larger Fostex fullrange drivers see the Fostex FE206E / FE206En driver modifications and tweaks page. These modifications and tweaks are suitable for the Fostex (FE83En, FE103En, FE126En, FF85WK, FF105WK, FF125WK) drivers and can likely be applied to similar small speaker drivers that also use a stamped steel chassis. The modifications and tweaks are generally focused around the idea that the light-weight stamped steel chassis can "ring". For those who don't want to permanently alter the fullrange speaker driver, the modifications are reversible. ![]() Some examples of the simple and inexpensive modifications which can be made to these speaker drivers are described below. There are many great modifications and tweaks for the smaller Fostex fullrange speaker drivers. ![]() To find the right tape for your job, visit Fostex Fullrange Speaker Driver Modifications and Tweaks Be careful when using this method on wood surfaces, however, as strong heat can damage the wood surface itself. This can easily be done with a hair dryer. Check out this video that demonstrates 3 ways to remove duct tape adhesive from glass:Īnother way to remove the residue is heat this destabilizes the bond the adhesive has with the wood surface, allowing you to scrape it off easily. Warm, soapy water is a great solution for acrylic, plaster or vinyl surfaces. Vinegar solutions, alcohol or WD-40 can also be effective. A putty knife, run slowly and steadily over the affected area, can remove residue from surfaces, but it risks damaging any paint on the surface. There are commercial products that you can use to remove tape residue, but there are other solutions as well. Using duct tape in an inappropriate situation can result in far greater issues than just residue. Also, make sure you’re using the right tape for the right application and surface - duct tape shouldn’t be used to seal packages or air ducts, and higher-strength tape can result in more leftover residue. This not only reduces excess residue, but it also ensures that the tape’s bond with the surface is stronger. Before you applyįirst, make sure that the surface you are working with is clean and dry. Follow these steps to both mitigate the residue itself and remove easily. The residue this adhesive leaves behind can be tricky to remove. Duct tape’s versatility and strength comes from its rubber-based adhesive. Duct tape residue can be mitigated by proper application and removed by a variety of methods.ĭuct tape is an incredible tool to solve a variety of problems, from on-the-job fixes to home projects.
