Product Description

Designed not only for super high efficiency with a huge dynamic range, but also for the ability to run full range without a subwoofer.  


This easy to assemble kit also includes the front speaker baffle.  It's CNC cut so the woofer and SEOS-12 waveguide are recessed to the correct depth.  You can build your own enclosure using the photo of the cut sheet shown above.  To see a larger version of the cut sheet, after you click on the thumbnail, just right click the image and save it to your computer to get the full sized image. 


You can also order the CNC cut 2cuft flat pack at this link.

    Speaker Notes

    This kit comes with the front baffle and a cut list to build your own speaker box.  You simply build a completely inclosed box that measures 14.5" wide x 26" tall x 13.5" deep.  Lay the included baffle on top of your box and simply trace the woofer hole, waveguide hole, and port holes on to your enclosure.  Cut those pieces out, then finish the box by gluing the baffle directing onto your speaker.

    If you don't want to build your own enclosure, there will be a unassembled box available in the flat pack section.
