DXi is Polk’s latest full line of loudspeakers, subwoofers and PA amplifiers that can turn any ride, any journey, on land or water, on two wheels or four, into an exhilarating power trip of real sound and exhilarating energy. That’s the real performance DXi offers over every other mobile brand. And it’s brought to you by a legend in the audio industry, Polk.
Your Ride, Our Sound
DXi is rugged enough and reliable enough that it can go just about anywhere, including on water. Not only will DXi play loud enough to overcome a boat engine and other sounds on the water, every DXi loudspeaker will perform reliably. That’s because they’re marine certified to stand up to harsh aquatic environments.
Technology & Features
This is How You Turn Up the Style
The look is about more than performance. It’s about making every detail count, from the wiring harness under the hood to the fit and finish of your loudspeaker installs. Even before you fire them up, the DXi Series delivers with its clean lines and contemporary styling.
DXi Coaxials & 3-Ways. Because Sometimes Space is Tight
Hey, maybe a full-blown component system and a DXi sub enclosure in a SmartCar isn’t all that practical, but some DXi coaxials will fill the bill quite nicely, thank you. The DXi Series includes: a 3 1/2-inch diameter coaxial, a 4x6-inch plate-style speaker and a 6 1/2-inch coaxial that can drop into a variety of applications in nothing flat.
DXi Series Component Systems
You’ve fine-tuned your car, now fine-tune your car’s audio with a DXi component system. Components give you the ability to create incredible sound despite the limits of a car’s acoustic environment. That’s when you want the DXi6500 6 1/2-inch component system. It will definitely add the extra adrenaline and great style.
Every DXi Speaker Comes with a Boatload of Reliability
Every DXi series loudspeaker is designed not only to withstand the demands of a car’s sun-baked climate, but corrosive marine environments, too. That meant subjecting every DXi speaker to ASTM (American Society for Testing and Materials) scrutiny to ensure they were as at home on the water as they’re on the street. Even DXi’s optional white grilles, developed specifically for marine installs, have been tested and marine certified.
The DXi Series was subjected to a series of grueling accelerated weathering tests to see if they could stand up to a harsh marine environment. We subjected them to hundreds of hours of salt fog, intense ultra violet light and temperatures ranging from minus 40° C (-40° F) to +85° C (+185° F), and DXi passed with flying colors. Proof that marine certified DXi loudspeakers with superior materials and excellent engineering will always rock on water.
Extreme temp test: cycles from -40°F to 185°F at 50% humidity for 48 hours.
Extreme temp test at high humidity: cycles from -40°F to 185°F at 95% humidity for 24 hours.
Extreme humidity test: 140°F at 95% humidity for 54 hours.
UV/Salt-Fog materials test, based on military specifications for “ASTM D5894” and “Mil-Std 883” tests: alternates one week of UV and one week of salt fog exposure, for six weeks (1008 hours total).
UV/Salt-Fog whole speaker test (based on military standard “Mil-Std 883 method 1009 8” test): UV and salt fog exposure, 24 hours.
