With a native tune (and porting) for 16 Hz the SVS 16-46 PCi will deliver very low freq bass with no group delay for music bass frequencies (in other words "tight" bass). The drawback with the low tuning is a bit less max mid-bass output, but your room is small enough in volume that that should not matter. Very good choice if you do not want to DIY a subwoofer enclosure.
