Dual 4-ohm voice coils

This sub's dual 4-ohm voice coils allow you to wire your system to draw max power from your mono amp or to safely hook up multiple subs. Match a DB+ sub to a suitable enclosure, and enjoy impressive bass punch rarely found in this price range. Polk Audio tests this sub rigorously for environmental effects caused by sun, moisture, and extreme temperature changes. They even certify this sub for marine applications, so they're a great choice for your boat too.

To drive this single subwoofer, we recommend a mono amplifier rated between 275 and 550 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Features

Dual 4Ω Voice Coils: This woofer features dual 4Ω voice coils, for wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When wired in series, the woofer presents an 8Ω load.

Marine Certification: Polk DB+ series speakers are marine certified (IP56 rated), making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals are not covered, we do not recommend using them in salt water environments.

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Sealed Box Volume: Polk recommends a sealed enclosure between 1.25 ft³ and 3.5 ft³.

Ported Box Volume: Polk recommends a ported enclosure between 1.75 ft³ and 2.25 ft³.

Q
Will a 1in polyfill lined 1 cu.ft sealed box work ok with this sub?
[ Travis  Dec 26, 2018 ]
1 answer
A
Yes it will work very well with this subs due to they are low profile and you wouldn't have any problem enjoying them
[ Richard D.  Dec 26, 2018 ]
Q
What is the total impedance of this subwoofer? It states "dual 4 ohm voice coils", does that imply they are in series for 8 Ohm, or in parallel for 2 Ohm, or is the overall impedance 4 Ohm?
[ Kenny  Feb 22, 2018 ]
1 answer
A
It means there are two 4 ohm coils, so you can wire it in series or in parallel--however you'd like. It comes with a handy wiring guide to help you figure out the right way to wire it for the impedance you need.
