Your Ride, Our Sound. Even Sweeter.
This bad boy slips easily into a door and like all DXi loudspeakers delivers the awesome sound quality people have come to expect from Polk. Of course DXi521 comes with the full complement of exclusive Polk features that make it an exceptional value for the price.
- Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
- Polk's proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
- Composite cones feature tremendous stiffness-to mass ratio; the cone's lower mass translates into faster transients and finer detail.
- Aluminum dome tweeter easily handles higher volume levels and also offers a higher power handling capability.
