W7 subs feature six different patented technologies which give them their edge:
- W-Cone™: a dish-shaped outer cone is supported by a second W-shaped inner cone attached to the the sub's voice coil structure. The light mineral-filled polypropylene cones respond rapidly for accurate, distortion-free bass without unwanted coloration.
- OverRoll™: the oversized polyether foam surround extends over the edge of the mounting flange for more bass output without sacrificing linearity.
- Floating Cone Attach Method (FCAM™): cone-bonding technology keeps the voice coil centered during long excursion.
- Plateau-reinforced spider attachment: a collar on the voice coil eases stress on the spider for extended excursion and improved reliability.
- Elevated frame cooling and cross-drilled pole-piece: cone movement pumps air through vents in the frame and machined holes in the pole piece, keeping the voice coil cool.
