5 The Mighty MinirigEnfused | 15/03/2013 | See all Enfused's reviews (3)A fantastic example of good old British engineering, solving a very specific problem - how can I take my favourite music with me wherever I go and share it with my friends? Thankfully, with the advent of the iPod and the smartphone the first part of this puzzle (the music source) was solved some time ago, but what about the speakers? Smartphone speakers are useless and the plethora of portable speakers launched over the years have all sounded terrible and suffered from poor battery life.Enter the mighty Minirig, a small aluminum "box" about the size of a roll of packing tape that contains a battery, amplifier and speaker able to fill a room with whatever sound is connected to it for up to 50 hours! It is (very) loud but more importantly, it sounds stunning. As a discerning music fan (dare I say audiophile) the sound separation between the bass, vocals and detail is so good that you quickly forget that it isn't even stereo! By connecting another speaker or several - they can even be daisy chained - you can go stereo and power a big party.It is apparently the result of three years of research and development by a British Inventor and is hand-made and sold directly from his (small) company in Bristol. A lot of big players have and continue to launch "portable speakers" and quite simply none of them come close to this amazing magic box.Arthur C Clarke once said "any sufficiently advanced technology is indistinguishable from magic" - every time I listen to my Minirig I have to agree!!
