At the beginning of the summer I decided that I wanted to put my new router table to good use, so I designed a pair of translam enclosures for the pair of Elemental designs e8as that I had laying around. They'll be paired with the CSS/Dayton Bookshelf speakers I built a couple years back (which are still in progress :P ). I'm planning to cross them over around 80hz, and they'll be driven by the front channels of my old Kenwood 5.1 receiver (100rms per channel @ 8ohms).
They'll make their home underneath these speakers, taking the place of the wobbly folding tables. Sorry for the terrible picture:
CAD Rendering of the design:
Specs
1.3cf
~11.5 sq in of port area (combined between the two ports)
Tuned to ~27hz iirc
47 layers of 3/4" MDF per cabinet
~3.5 sheets of MDF will be consumed
Over the course of the summer a few other projects took precedence over this, but I finally started making sawdust a couple weeks ago.
Templates cut out from 1/2 MDF. The left most template is for the bottom two layers of the enclosure, where the drivers will mount. The center was left intact to allow me to transfer the center point from the paper template (which I printed out from an AutoCAD file) to the MDF template, and then to the first layer. The next template to the right was used to cut out the internal cavity of the cabinets. To the right of that is the template for the bracing, which will be placed every 10th layer. The final template is for the 5 top-most layers.
After ripping the first sheet of MDF down into 7 strips, I traced the first template onto the MDF and roughcut the outer perimeter and port with a jigsaw to make 28 'blanks'.
The first blank for each enclosure was attached to the template and trimmed flush on my router table. This first layer then served as the template to which I trim the next layer. This method will be used throughout the whole build so that I don't have to precisely align each piece.
First two layers:
Driver holes routed out in the first two layers, the third (which is actually the bottom-most layer) attached, and the holes for the speaker spikes drilled:
Third layer trimmed flush, sub test fit:
T-Nuts pressed in for the spikes:
Fourth and fifth layers attached, and ready to be trimmed flush tonight.
I'm hoping to get 4 or 6 more layers added to each this weekend.
