The weighted companion cube will never threaten to stab you and, in fact, is a subwoofer

From the techPowerUp! forums comes an awesome weighted companion cube subwoofer built by the metonymical user named [Cube].

This build started off as a coffee table that was to have an oval glass top (no word if the edges were going to be blue or orange). The guts of the cube are taken from a 400 Watt sub. As any good sub builder would, [Cube] kept the air volume and port tuning of the donor box.

We’ve seen a companion cube sub before that featured EL wire for a ‘glowing cube’ effect, but [Cube] may have taken things a little too far by including glowing rings on each side of the cube. The rings lit by 2,500 LEDs mounted on pieces of perspex and wired point-to-point. While [Cube] claims he’s ‘not a electronics guru,’ he certainly has a lot of patience to assemble those lights.

Check out [Cube]‘s YouTube build video after the link. Credit to [Todd] for sending this one in.

  1. Awesome work. And Portal really gives itself to great mods like this, it’s full of iconic characters (even if it’s a lifeless cube!).

  2. Holy shit! The craftsmanship of thus is amassing! My hat is all the way of and on the floor. Mr. [Cube] really made something out of the ordinary here! Now make a giant portal button for it to rest on!

  3. What if an LED fails? He covered them with glue. I’m not an expert but I think he should have considered that. With some many LEDs failure is not far away. Also having them hooked up on some kinda animation circuitry would be cool. But anyways great mod.
