The SVS PB13-Ultra is a high performance 13" powered box subwoofer and is SVS' flagship model from their Ultra box series, intended to compete with in-home theater and media room subwoofers.  The subwoofer is designed with a 13.5" die-cast aluminum frame which houses a high-excursion SBR rubber surround with an integrated top gasket, dual linear 9" spiders, and a 3" aluminum voice coil.  It includes a flush-mounted 750-watt BASH amplifier which adjusts to the room size and utilizes a high efficiency linear circuit for powerful sound without cost penalties. 

The enclosure of the PB13-Ultra is computer designed with three 3.5" high-flow front-firing flared ports with CURVE venting to allow for proper air flow in the unit.  It comes with a curved perforated magnetic grill in a choice of steel or traditional fabric and is available in a variety of finishes including oak or rose nut veneer, gloss black, or textured black.  The subwoofer has an MSRP of $1600 and comes with a 3 year limited warranty.
