Your Ride. Our Sound.

Smaller driver diameter means you can mount the DXi5250 in tigher spaces, and because it’s a component system you have the freedom to tailor the sound in your vehicle’s environment. Polk’s Legendary sound comes through loud and clear, thanks to Dynamic Balance® driver technology and silk/polymer dome tweeters.

Dxi5250 Features:

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.

1-inch liquid-cooled silk/polymer composite dome tweeter for clear, detailed highs.

2nd-order Butterworth outboard crossover for component system sound—at a coaxial price.

Flush & surface swivel mount cups are supplied for easy install flexibility.

Vented crossover housing gives you a choice of hidden wire channels for easier, more professional-looking installs.

Electronic tweeter protection circuit protects your tweeters from abuse for reliable high output sound.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
