Pop quiz: What image first comes to your mind when you hear Bluetooth speaker system? Is it a small, portable, single-cabinet pseudo-stereo box with meager amplification? Would it blow your mind to imagine a Bluetooth system that’s actually a 2.1 desktop system, complete with two stand-alone two-way speakers, a separate amplifier/control box and yes, a separate subwoofer? Take a look at the Thonet & Vander Rätsel BT 2.1 Bluetooth system with a 75-watt. Sadly, I’ve gotten so accustomed to tiny little Bluetooth speakers that my mind was suitably blown.
