Soundboks is a small speaker company that's been making one BIG specialty travel-speaker since about 2015, the Soundboks. At 26-inches tall and 34-lbs, it's not exactly "portable" but it does have a handle. With XLR and TRS input\/outputs and Bluetooth, the speaker has been a popular alternative to PA systems for music professionals that need to fill large outdoor spaces with very loud sound.\n\nSoundboks just released a new, more portable version of its big speaker called "Go". At 20-lbs and 18-inches tall it's barely portable. This is a big, very loud Bluetooth speaker that lacks the XLR in\/outs for pros. This one is built to be more of a straight Bluetooth speaker, with a handle on top and an option strap, it can GO with you anywhere you need powerful sound. I got to test the speaker at a backyard barbecue recently and it was the first time I got to experiment with running it at extremely high volume, and it displayed impressive power. Blasting Prodigy much louder than the neighborhood would have liked didn't seem to strain or distort. Although, it's not exactly a finely tuned, revealing kind-of speaker, dripping with sweetness in the midrange. You won't use something like this for deep listening sessions, it is after all, a Bluetooth AAC\/SBC speaker. But for its stated purpose it does a great job, projecting music across a wide area. It seems to like hard rock, aggressive electronic or dance music best, exactly what you'd expect from a "party speaker". Its rugged build quality has potential to make it a great job site speaker for a musical companion at any construction site. The removable battery claims 40-hour lifespan before needing a recharge while running up to half-volume. An IP65 rating guards the speaker against continuous splashes of water or dust and its rugged shell will endure many years of continuous use.\n\nRead Soundboks Go First Look:\n\nSOUNDBOKS Go: Loudest Bluetooth Party in a Box Speaker Ever?
