The PC12-Plus is a midsize subwoofer intended to be used in rooms of small to medium size.
The PC12-Plus comes with three foam port plugs, which operate as tuning devices. Left unplugged, the ports increase the sub’s output -- with all three ports open, the PC12-Plus provides maximum output in most rooms, down to 20Hz. However, the PC12-Plus can be tweaked to dig even deeper. According to SVS, plugging one port lets the PC12-Plus go down as far as 16Hz. Plugging all three ports fully seals the cabinet. This configuration, sometimes preferred by music purists, could, in small rooms, bring the bass response down into single digits, where bass is more felt than heard. SVS doesn’t recommend plugging two ports because, they say, this can cause the remaining port to chuff; that is, make the unwanted noises produced when large volumes of air are forced through a port.
Note, however, that if the port plugs are used to extend the PC12-Plus’s low-end response, the larger bandwidth the sub is asked to cover will also reduce its overall output, particularly between 20 and 50Hz, where a lot of bass content resides in both music recordings and film soundtracks. SVS says that some customers don’t mind trading a bit of upper-bass response for a deeper reach. But no matter your personal preference, the sub’s decreased output with all ports plugged means that that configuration should be used only in small rooms, which tend to have an inherent "gain" -- a naturally rising response -- at the lowest frequencies.
On the rear panel, in addition to controls for a built-in parametric equalizer, are settings for gain, subsonic filtering, phase, and crossover (with a bypass option to route that last function to an A/V processor).
