I just unearthed a couple def-tech buyout woofers after some recent posts reminded me that I may have used them long ago as door speakers in a previous vehicle. Lo and behold, I located them and they had collected a decades worth of dust in the basement. Since I only have 2, a quick search led me to Wolf's Deuterium design. I dug up some silkies and ordered the required crossover components. I built the cabinets from 1" x 12" poplar boards bevel cut on my 12" sliding miter saw to form the sides, tops, and bottoms. 1" x 6" poplar boards were used for the baffles and backs. I 3D printed the ports. I still need to assemble the crossovers and finish the cabinets. Here are some pics of the progress.

Everyone needs more speakers, nice work. -
Pretty handsome speakers. Small enough to make without guilt.

Nicely done! I haven't seen those in a bit...

Nice job! I sure could use one of those woofers (299-706) at a some what reasonable price - not $40 each.Comment

Nice job, pretty cool you were able to 3D print your ports! Does that take much programming to tell it what you want or are there files floating around for that sort of thing? Does the poplar stand up alright, as far as vibrations?Comment

Thanks everyone. I tested the speaker without a crossover connected to my modified Ikea Symfonisk Sonos. In my testing, it looks like it uses a 1.8kHz crossover point which I think is similar to the Deuterium crossover point. It sounded a bit lacking in the highs, but a boost in the treble via the app EQ helped. When I ran the Trueplay calibration I ended up losing mids and noticed a low bass and high treble boost. I noticed this in my testing of the Symfonisk as well. I plan on assembling the crossovers and testing them with the Symfonisk to see what difference this makes and will then compare this to the speaker being powered by a conventional amp. If I find that the Symfonisk does a good job, I may transplant the Symfonisk guts to the Deuterium.
I bet there are STL files of ports you could find, but there are many free CAD apps out there. OnShape is a great web-based CAD program that is free for students and hobbyists/makers.
This speaker is 14"t x 7"w x 11.25"d built from 3/4" poplar boards. The 1" x 6" is a solid board and the 1" x 12" is laminated. With a 3/4" baltic birch brace in the middle, the speaker is very solid. I plan on adding butyl dampening and some foam.Comment
