This paper describes a loudspeaker cube with four transducers on its horizontal facets, designed to enable sound radiation with adjustable first-order beam control. Design and equipping of the cubical loudspeaker is presented along with two open data sets containing multiple-input-multiple-output impulse responses (MIMO-IRs) of our measurements. The first one contains 648x 4 MIMO-IRs from input voltages to a grid of microphones at a fixed distance. The second set contains 4x 4 MIMO-IRs from input voltages to loudspeaker cone velocities, and it characterizes the active and passive transducer coupling through the enclosure that we aim to equalize/decouple. Based on these measurements we present a simple FIR filter design required for beam control of which we discuss operation range and limitations.
