The SB13-Ultra was delivered in a moderate sized box that somehow still weighs about 100lbs according to my highly accurate back scale. After cutting the tape and popping the top open I could see that the packaging was substantial and very protective. The SB13-Ultra is double boxed with heavy gauge cardboard. Inside of the box are die cut foam inserts at the top and bottom and a couple of thick foam corner inserts. Removal of the SB13-Ultra was simple and took maybe 5 minutes. Contained in the boxes with the SB13-Ultra are the metal grille, the power cord and a quick start guide. The full length owner’s manual is available online from SVS. The SB13-Ultra isn’t overly large or imposing but it is a bit heavy.

” The SB13-Ultra’s finish is among the best you’ll find regardless of price. The SB13-Ultra sub will easily pressurize medium to large-sized rooms with clean and rich bass.”

“The cabinet of the SB13-Ultra subwoofer is constructed of MDF (medium density fiberboard) and contains a large window brace internally which the motor of the driver fits into. This brace stiffens the top bottom and sides of the cabinet and also helps support the heavy driver motor and relieves stress on the front baffle and driver mounting area. ”
