Upgrade your desk with these modular 3D-printed speakers! While the rest of the office jams with their plain black and silver sound cubes, you'll be listening in style from your very own custom set. With only a handful of simple parts, you'll be able assemble or tear down these speakers in minutes. There's no need for a fancy, high-end 3D printer to make these, just a simple desktop model and a handful of dowel rods and you're nearly there.

Step 1: Parts and Materials

(2x) speaker (RadioShack #: 55076557) web only and sold in pairs

amplifier (RadioShack #: 55065111) web only

stereo to dual phono cable (RadioShack #: 42-494)

3D printer filament (RadioShack #: 277-237)

20' x 1/4" square dowel rod

(16x) M3 x 20mm screw

(16x) M3 lock nut

<p>A speaker without box loses up to 75% power.</p>
<p>An unboxed, unbaffled speaker loses nearly all the bass. A speaker run without a box will also hit the limits of travel on the bass notes and be damaged at what may seem like modest volume levels.</p>
<p>I could live with the efficiency loss but not the acoustic tragedy, or the pain in cleaning dust off, or that it will probably rattle itself apart if used for more than moderate volume levels.</p><p>Overall it's a great example of &quot;just because you can do something that doesn't necessarily make it a good idea.&quot; </p>
<p>I'm aware. This is a decorative case.</p>
<p>Repeat after me, form follows function.</p>
<p>also encase the back of the speaker in pvc tube or cap packed with insulation and sealed with silicone and base will come back along with form</p>
<p>makes an excellent frame for an underwater synchro speaker</p>
<p>Look great and thanks for sharing. Disregard the crybabies it was obvious to anyone with a brain that these would not have great sound quality. yet people think they need to point out the obvious. I am going to turn this into a class project</p><p>thanks</p>
<p>awesome </p>
<p>So nice! Is the resonance also good in open structure?</p>
<p>The resonance is lost, but I made this just for the design.</p>
<p>And a good job of it! Sure, not a 'proper' speaker enclosure, but it's a pretty nice frame, well executed and novel - not just another mini-cube desk speaker. You've done nice work here and I appreciate your effort and sharing. Keep creating!</p>
<p>The Instructable title is a bit misleading. You didn't actually 3D print any speakers. The title in the YouTube video, &quot;3D Printed Speaker Case&quot; seems more appropriate. </p>
<p>Nice work! When I was experimenting with small full-range speakers during my AiR residency I discovered that it was very easy to make Fusion 360 compute the volume of a hollowed object... If you wanted to make an additional piece to get some of the bass response back it would be easy to model a hollow cube that holds with the aesthetics of your cool design and just bolts onto the back of the speaker surround or the top clips. For a 4&quot; speaker you only need about 32in^3 of volume for a sealed enclosure so it wouldn't muck with the clean design of your enclosure, and it would thump more and be easier on your amplifiers.</p>
<p>Thanks JoeJoe, definitely something to look into!</p>
<p>I don't see a 3D printed speaker, but I do see a 3D printed speaker enclosure/mount</p><p>I am quibbling but there is a difference!</p>
<p>To me, that is not a case, it's merely a support. It does not separate the speakers' back radiation from the front radiation, resulting in phase cancellation and lack of bass response. Speakers need to be in a sealed or ported enclosure to have good bass response. This &quot;case&quot; may be different looking, but acoustically, it's useless! You might as well just have a raw speaker laying on your desk.</p>
<p>This is an awesome idea! Growing up with tinker toys and erector sets, this takes me way back...</p><p>For all those folks out there that point out the need for an enclosure, maybe add something cool inside? Looks like you have plenty of room for something creative!</p><p>Again, awesome idea</p>
<p>It's pretty but you have no idea what you are doing in terms of actual speaker design. Having it in free space like that guarentees no low fequencies. You might want to look here: <a href="https://docs.google.com/file/d/0B_l73GVBBlIUNTc2YTc2YTktNTNmYi00YWNmLTlmY2ItZTU0MTRhMzdkYTAy/edit?pli=1" rel="nofollow"> https://docs.google.com/file/d/0B_l73GVBBlIUNTc2Y...</a></p><p>Nice to look at though.......</p>
parts express. com has a good selection of parts. it's hard on the speaker to run it this way. there are several other ways to design enclosures. you can get away with a smaller enclosure if you use an enclosure such as those designed for car speakers.
<p>A speaker without box loses up to more 75% power. Acoustic short circuit!</p>
<p>Nice. I can't wait to try 3D printing, but it's aint gonna happen soon as I don't have a space for it :)</p>
<p>They do look nice, but if you covered them in acrylic/Plexiglass, you'd keep the look AND have some of the power/resonance back.</p>
<p>Great looking speakers! It looks like there are a lot of cool directions you can go with this design.</p>
<p>Thanks! Yeah, with a couple different joint pieces, you could really make a lot of different shapes!</p>
I heard speakers don't work as well without a complete enclosure. Sorry, didn't want to be left out :) The wood could be stained, painted, or even decorated with seasonal decor. Spider webs with a big spider for Halloween, for example.
<p>They sure look good! Corners would look even better cast from concrete.</p><p>The question I have is how's the sound? Don't the speakers benefit from full cases? I don't know that stuff, so just wondering.</p>
<p>The sound is pretty nice. The resonance is lost, so the volume doesn't max out, but I built these as a decorative desk set, not for 5.1 surround sound haha.</p>
