SVS has long been known for high performance subwoofers and the PB12-NSD while the most cost effective vented subwoofer in the current line up, still musters up a hefty amount of room filling bass. (Also offered is the PC12-NSD cylinder version which is said to have nearly identical performance.) Tipping the scales at 66lbs the heart of the PB12-NSD is a quality 12" long throw, aluminum cone driver vented through a 4" diameter flared port, all housed in a large, well braced, black vinyl wrapped enclosure, which happens to be the only finish option available. The brains of the operation come from a 400 watt version of SVS's Sledge amplifier platform. This combination available shipped to your home for $769, provides extension with authority to 20Hz and perhaps a bit lower in some rooms. Build, performance and parts quality for this price range were all found to be exceptional. While the PB12-NSD is short on finish options and may not have some of the extra bells and whistles offered by other subwoofers on the market, what it does do very well is the task of producing accurate and powerful bass with depth and finese that most other subs in this price range cannot match, as evidenced by the PB12-NSD achieving the Audioholics Large Room rating. At the end of the day that is what a subwoofer is supposed to do and the PB12-NSD does not disappoint. \n\n\nDiscuss "SVS PB12-NSD Subwoofer Review " here. Read the article.
