The Grotto has a three position phase switch and along with a pair of long interconnects would allow for an optimal placement which should be enough to obtain a good deal of sonic satisfaction.
If your dissatisfied with its performance and decide on a more sophisticated DSP subwoofer keep the Grotto because you may be able to slave the equalized line level signal from the DSP sub. Together they may better load the room and decrease room nodes.
