On the physical side, sealed cabinet subwoofers are more forgiving of poor room placement, can be placed optimally in more positions in a room and, most importantly depending upon where in the world you live, there is no way for small animals to enter the cabinet and live inside. That response will also exhibit less phase shift, lower group delay and reduced ringing in the time domain. Which means there isn’t any room on the front or the back for a bass reflex port, which in turn means that Velodyne’s new German owner is sticking with Velodyne’s philosophy of building only subwoofers that have sealed enclosures.Īnd why wouldn’t Velodyne want to stick with building subwoofers with totally sealed enclosures? On the technical side, the frequency response of a subwoofer with a sealed enclosure will be flatter across the pass-band with a superior and smoother roll-off below that pass-band than that of a bass-reflex enclosure, or even one that uses an auxiliary bass radiator.

You could easily improve the looks by tucking the tag in or cutting it off entirely, but both tactics would then make it difficult to remove the grille.Īs you can see, the bass driver occupies nearly the entirety of the front baffle, which is about 35cm on each side, which means that when standing on its four rubber isolation/damping feet, the DB-12’s top will be 37cm above floor level.Īround the back of the DB-12 is the 200×230mm amplifier plate that doubles as the heat-sink for the Class-A/B amplifier inside it that Velodyne rates with an output of 350-watts, so this, too, occupies nearly the entire rear of the subwoofer. This tag hangs out from the grille and, to my mind, looks a little silly. The only impediment to these good looks is that Velodyne has fitted a tiny cloth tag to allow you to easily remove this grille if you wish. The DB-12 introduces a new industrial design for Velodyne, which sees the bass driver recessed into the front baffle and covered by a circular grille that is also recessed into the baffle so it ends up sitting flush with it, which makes for a really classy look. So sometimes, size is more important than quantity! Sd is an important specification because it means the Velodyne DB-12’s cone can ‘drive’ nearly half a square metre of air! By way of contrast, a typical 254mm (10-inch) diameter cone has a cone area of around 230cm², which means that two DB-10s won’t move as much air as a single DB-12. On the DB-12, this is 250mm, which puts the effective cone area (Sd) at 490cm². However it’s the Thiele/Small diameter (the distance from the middle of the surround suspension on one side to the middle of the surround on the other) that is the most important specification because this is what determines the volume of air in front of the cone that will be turned into sound waves.

As its model number suggests, the bass driver has a nominal diameter of 12 inches (305mm), which makes it the second-largest bass driver in the ‘Deep Blue’ series – the other models being the DB-8, DB-10 and DB-15.ĭespite Velodyne rating the DB-12’s bass driver with a diameter of 305mm, it’s actually rather larger again than this, because I measured its overall diameter at 310mm.

The unique technology the new DB-12 does have inside it is Velodyne’s famous double-vented high-excursion bass driver with its four-layer voice-coil and dual ferrite magnet.
