This is a relatively quick one - it's a basic frame that fits the Teenage Engineering TX-6 Mixer next to a very similiarly sized Ikea Frekvens mini bluetooth/Aux speaker. You obviously need a cable to get audio from one to the other.

It's not really for portability - the Frekvens speaker doesnt actually lock in, it just fits into the side of the frame with a small knob that fits into the hole where the speaker metal stand would go. This is just for keeping things vaguely organised on a desk. The TX-6 fits snug wwith a little thing that slides on once it is in place - the frame also hides the switch away between the speaker and mixer.
