Like all DXi loudspeakers?? the DXi461 is a refinement that keeps raising the standard for incredible sound at an affordable price. <br><br> DXi461 Features: <br>Klipp"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. <br>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. <br>Aluminum Dome Tweeter easily handles higher volume levels and also offers a higher power handling capability. <br>Neodymium is a rare earth material we use in all DXi tweeter magnets?? that's about 1/10 the weight of a comparable ceramic magnet and much more powerful. <br>Dynamic Balance polypropylene cones feature tremendous stiffness-to mass ratio. Lower mass means faster transients and finer detail. <br><br> <li>Dimensions - Oval Cut-Out Height: 6 (15.24
