Overview

Our take on the Polk dX3055

If just about any old car speakers will do the job for you, look elsewhere. The dX3065 system from Polk is a top-of-the-line performer for people who take their sound seriously. You'll love the way the 5-1/4" poly-mica composite woofer deadens resonances that detract from your music, while delivering tight bass and deep lows. The rubberized plastic surround provides a solid seal for accurate sound reproduction, and it'll hang tough under temperature extremes.

The rubberized plastic surround provides a solid seal for accurate sound reproduction, and it'll hang tough under temperature extremes.

For control, the tweeter can be swiveled up to 15° in flush or surface mounts, so you can direct sound where it does your ears the most good. Use the selectable crossovers (6-12 dB/octave), to fine-tune your music even further. Choose from 12 combinations of tweeter level, tweeter phasing, crossover frequency, and slope for the perfect musical blend. Add an amplifier for optimum sound.

Features:

Dynamic Balance Technology: Laser imaging research allows Polk to observe the resonances of different cone materials. Polk engineers have used laser imaging techniques to find the right combination of materials, geometry and construction needed to tune out response distorting resonances. The result is excellent bass and smooth, clear midrange response.

Woofer materials: The mineral filled polymer composite woofer cones produce clear, well-defined midrange output and accurate bass. The polymer/mica composite woofer cone material improves woofer performance by damping performance robbing resonances. The cone material is extremely durable, so it will withstand the temperature and humidity extremes of your vehicle's interior.

Co-molded Polymer/Rubber Surround: The polymer/rubber surrounds are co-molded with the cones to prevent the surround from separating from the cone. This type of surround is extremely durable and helps provide superior bass response.

Tweeter Materials: The 1" dome tweeters are made with a blue tri-laminate silk composite diaphragm. This combination of tweeter materials results in more accurate response, superior detail and high power handling. Each tweeter is made with a small, but powerful, neodymium magnet to keep the size of the tweeters small enough to allow a variety of mounting options.

3 Tweeter Mounting Options: This system includes mounting parts and hardware for flush tweeter mounting, surface tweeter mounting and angled surface tweeter mounting. In all three mounting configurations, the tweeters can be pivoted to "aim" their output for the best high frequency response and soundstaging.

Selectable Tweeter Output Level: Each crossover has a 3-position switch that allows you to select the tweeter output level according to system requirements and personal preference. The switches may be set to "-3dB", "0dB" or "+3dB" to tailor the tweeter output level according to personal preference.

2-way Crossovers: The included crossovers provide high pass filtered output to the tweeters and low pass filtered output to the woofers. Each crossover contains a jumper that sets the low pass filter roll off; the low pass filter roll off may be set to 6dB/octave or 12dB/octave. When the tweeter will be right next to the woofer, the low pass roll off should be set to 6dB/octave. If the tweeter will be more than 6-inches away from the woofer, the low pass roll off should be set to 12dB/octave.  The high pass filter is fixed at 4800Hz with a 12dB/octave roll off. 

Crossover Mounting: There are two mounting holes in the base of each crossover; screws to mount the crossovers are not supplied. The crossovers are not weather proof, so they should not be mounted in locations, such as door panels, that will expose them to direct contact with water.

Gold Plated Terminals: The speaker and crossover terminals are gold plated for corrosion resistance.
