Festool TopRock Systainer Bluetooth Speaker

A Storage System That Sings To a Different Tune

Storage containers that hold a variety of tools and other equipment are often important when it comes to keeping the jobsite organized. What if your run-of-the-mill Systainer (short for System Container) could serve another purpose? We’ve seen it with the Milwaukee Packout radio, Makita interlocking cooler, and other similar products. Now, the Festool TopRock Systainer Bluetooth speaker seizes an opportunity to fill the gap in the systainer-sphere. They’ve created a product that doubles down on its usefulness both on and off the jobsite.

Festool TopRock Systainer Bluetooth Speaker – The Big Deal

By integrating a fully-functional Bluetooth 5 speaker system on the lid, the Festool TopRock Systainer and speaker was born. The lid includes four speakers and a resonance chamber. It provides stereo sound by connecting a device to it via Bluetooth. You can even connect two TopRock speakers to the same device for even bigger stereo sound. Whether anyone actually drops $450 to pull this off remains to be seen—but maybe you work with a buddy!

The front of the lid houses the audio controls. These include a power button, a Bluetooth connect button, and volume controls. Next to these dials is a door for external power and a USB port, which charges external devices like smartphones.
