DXi 2013

Polk Audio’s DXi Series has been murdered out for 2013. The entire DXi line, coaxial, component and subwoofers, have been taken to a new level, re-styled for serious tinted-glass players and engineered with the polk sound that tells everyone you have arrived. You’ll find our most popular sizes and configurations. And you’ll find them at prices that make blacked-out high performance audio a must have. DXi takes your ride to the dark side.


Your Ride, Our Sound. Sweeter on the dark side.

DXi is rugged enough and reliable enough that it can go just about anywhere. Whatever your ride, DXi covers the range of car and motorcycle applications, plus anything else that comes with wheels. The series includes full range speakers, a full component system, subwoofers and complementary PA amplifiers. DXi has everything you need for power, for performance, for real sound quality as only Polk can deliver.

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 blacked out style.

This Is Where DXi’s Incredible Sound Comes From 

High Efficiency Design means less amplifier power is needed for more audio output. Meaning better sound and more volume using less power. The bottom line is DXi loudspeakers will definitely blow you and your friends away, whether they’re driven by aftermarket head units or factory installed electronics. (If you really want to punch your music up, you’ll want to check out our PA amplifiers.)

Dynamic Balance® Driver Technology—All DXi Series drivers, tweeters and subwoofers use our Dynamic Balance technology, which we developed in conjunction with the Johns Hopkins University. We needed a better way to analyze a speaker’s microscopic behavior to optimize the system’s performance. We used a laser interferometer, which gave our engineers a view of the entire vibrating surface of a driver or tweeter. They could observe the resonance which develops on speaker cones as they move. This resonance is at the root of frequency response distortions. With Dynamic Balance, which is a whole process for creating the ideal combination of materials, geometry and construction techniques, we tune out these unwanted distortions and dial in your music.

Klippel Optimized components for a driver to reproduce complex sounds accurately, the cone must move in exactly the same distance and manner in both directions of travel. The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, let us optimize the motor structure, voice coil alignment and suspension to yield the best possible performance.

 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 4x6-inch plate-style speaker, a 5 1/4-inch coaxial, a 5x7 coaxial 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 DXi6501 6 1/2-inch component system. It will definitely add the extra adrenaline and great style.

Your Ride. Our Outrageous Bass.

These are the subs your mother warned you about and your father wished he had when he was your age. Not only do the new DXi Series subwoofers make it easy to add bass to any audio system, they do it with more style, more performance and at a price that’s hard to beat. Here’s how our 12-inch subwoofers and 12-inch sub enclosure deliver big bass performance:

Subwoofer Features:

Optimized for high performance in virtually any enclosure type: sealed, vented and band pass.

Wrap-around rubber gasket seals the sub in your enclosure for airtight performance.

State-of-the-art laser-based Klippel measurement technology perfectly centers the subwoofer’s voice coil in the magnetic field, improving X-max and BL linearity, and the sub’s micro and macro dynamics, for deep, precise, bass!

Black matte finish composite cones are unbelievably stiff for real gut-pounding bass.

Injection molded ABS dust cap also stiffens the cone to suppress unwanted resonance for incredible low distortion, high impact bass response.

Big beefy magnet structure and motor assembly for high output bass with tight control.

Durable rubber surround for consistent, reliable performance.

Four-layer vented voice coil runs cool while your music stays hot.

Vented pole piece for higher efficiency and ultra-high power handling.

Fast-on wire terminals for quick, secure hookups.

Every DXi Speaker Comes with a whole lot of Reliability

Every DXi series loudspeaker is designed not only to withstand the demands of a car’s sun-baked climate. That meant subjecting every DXi speaker to ASTM (American Society for Testing and Materials) scrutiny to ensure they were ready to play no matter the what.

The DXi Series was subjected to a series of grueling accelerated weathering tests to ensure could stand up to  harsh environments. 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  DXi loudspeakers with superior materials and excellent engineering will always rock.

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.

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.
