BoomCases: self-powered amps built into old suitcases


Mr Simo's BoomCases are self-powered amplification systems built into vintage suitcases and briefcases. They run for seven hours on a single charge, and come with a built-in charging plug. Cost is $275 and up, which is steep, but here's a way to be stylish and audiophilic in one go, and they're hand-made by a skilled craftsman besides.

  1. So pretty! If you consider the real price of it, it’s a steal at $275. You can get a shitty looking foreign made one for cheap, but it won’t look as good with a fedora.

    1. That model 12 has a stiff casing with struts engineered for minimum resonance. These are made of old suitcases most of which were made out of lacquered cardboard or plywood.

      High end audio this is not, but I bet that they will still sound better than anything made by Bose.

      1. My old suitcases are made of steel, carefully selected spruce and hardwoods, and alligator hide. Cheap suitcases do not have alligator hide, they have cowhide or pigskin instead.

        “Lacquered cardboard and plywood” suitcases are not the norm for old suitcases, they are the norm for cheap piece of crap suitcases in all times and all places.

    2. I have a Cambridge Model 12. It was a bit of a fetish buy, and I’m not ashamed of that. The model 12 kicks ass. It’s not super powerful, but it will play plenty loud enough for a pretty big party. But the best thing about the model 12 is that it sounds very, very good. And for less than 10% more than the price of the BoomCase, you get stereo.

      On the other hand, you have to set up the model 12 — take the satellite speakers and amp out of the case, and hook it all up. It’s not grab and blast.

      If your goal is to walk through your neighborhood, blasting the neighbors out, then maybe the BoomCase is for you. If you are wanting portable hifi stereo playback, then I’m with Classic01: you really want a model 12.

  2. i have, as an artist, built 6 or 7 suitcases with speakers / car amps in them, for my mobile audio project.
    (see here for a picture -> http://www.nerdlab.nl/koffer_2.jpg

    they can run (on a small accu, for 12 – 24 hours

    the ones in the picture run on a car battery because i used a 1000watts amp and an old laptop / soundcard setup

    it’s fairly easy to build them, just use passive crossovers and a used car amp. speakers and suitcases from a thriftstore,
    accu’s you can get for almost nothing, say 10 dollars at a car parts shop. (or from a backup power of an elevator – that’s how i got most of mine :) )

  3. Makers: If you want to make your own you search online for “audio amplifier boards”. There are little 4 watt wonders all the way up to 400watt monsters that you can buy for actually pretty reasonable prices. I saw the 400 watt monsters or more reasonable ones for $55ish online at parts-express.

    There are many places to source them and speakers as well online and some of these amplifier boards work pretty well on battery power.

    The real limiting factor is your time. If you want to get snazzy about it you can put in some leds and even do some custom fiberglass molding or custom speaker grills..

  4. Can we have full license to beat up anyone who checks through an airport and fires one of these up??

    I’m sick to death of others pushing their poor choice of music on the rest of us…

  5. It looks cool, but making a speaker enclosure that accurately reproduces the audio spectrum is more difficult than it looks. You can’t just throw speakers in a box and expect it to have a good acoustic response.

  6. I’m sure this thing rattles and hums like crazy when it’s booming. This is for noise freaks, not audiophiles.

  7. Man, I’m kind of annoyed because I just bought a suitcase to do this to as well, for a costume I’ve created. At least mine is designed specifically for noise freakiness.

  8. I don’t know how much space is left inside, but these would be rad for a portable version of your standard circuit-in-a-suitcase noise set up.
