Normally we suggest using our subwoofers with the logo facing the listening position. That means the driver will face the right side of the room. We find that this typically couples best with the room in the lower frequencies, although the wavelengths at the usable frequency range will distribute in a 360-degree pattern all around the subwoofer.
You can absolutely experiment in your setup to see if there are other ways that work better. By facing the drivers directly towards the listening position instead, you may feel it has a slight advantage if you use a higher crossover frequency, where the upper midbass will have slightly better dynamics.
