Listening to my favorite music tracks in high volume levels has always been one of my favorite hobbies and that applies not only when I'm at home or in my car but also when I'm on vacation (like now). However although both when I'm at home or in my car I've made certain to have a decent amount of volume to cover my needs the same does not really apply when I'm away since the majority of portable speakers are not much larger than a can of soda and thus the volume levels produced (although quite good in some cases) are nowhere close to the ones a complete speaker system is able to. Well luckily this industry never ceases to amaze me and so today we will be taking a look at the latest wireless portable speaker by TDK the quite massive A73 Boombox.
