Speaker, Loudspeaker, Bookshelf, Enclosure Plans Ellipse E104, cedar pine

These are plans to build your own original custom speaker design. The plans use quality Dayton Audio components such as the RS100P-4, 4" woofer and the DC28F-* 1-1/8" silk tweeter. The enclosure was developed using speaker enclosure software as well as a good old fashioned calculator (I've been designing speakers for quite awhile now). In addition, I have included the plans for the speaker stand shown called the BM120 and will be posed for sale separately in the near future since the stand can be used for any flat bottom smaller speaker.

As shown, the speaker enclosure is made from Cedar with a Blue Pine inlay on the faceplate. These woods are common in northern Washington State and I did the full circle lifecycle of these woods from log to finished product. However, the wood can be any material you choose even MDF or similar if you prefer a painted look. The best part of these plans is you can really make them your own and I look forward to seeing everyone's finished project and the variations they chose.

The enclosure measurements are 26" tall x 6" wide x 5" deep (not including the stand). Included in the downloadable package are full scale 'B' PDF drawings, DXF files, STL files, and basic instructions to get you started. I hope you enjoy this project as much as I enjoyed designing and building it. Please contact me if you have any further questions. These plans do NOT require a CNC router and basic shop tools are fine, however, you should have knowledge in woodworking before attempting to build this project.

This can be a rewarding project and a very unique one at that. Very few speakers are shaped as modern and have this good of sound quality for such a small package. Make it your own with different woods or paint or ?. I would love to see your final result so shoot me an e-mail and pic when you are complete. Dont have 3D CAD software? Download Fusion 360 for free. Other mechanical CAD or Mechanical CAM software will work as well such as BobCad or CamBam or Meshcam among many others. - even old versions.
