Our take on the Polk Audio DB652 Ultramarine Dynamic Balance Coaxial Speakers

The Polk Audio DB652 is a 6.5-inch two-way coaxial speaker built around Polk's Dynamic Balance driver design, with a marine IP55 rating for water and dirt resistance. It handles 100W RMS (300W peak) at 4 ohms with 92 dB sensitivity, so it plays loud off modest power. It suits people replacing tired factory speakers in cars, trucks, ATVs or boats who want fuller sound without adding an amplifier. Against budget coaxials it offers marine sealing and a wider 40 Hz to 22 kHz range; against dedicated component sets it gives up separate tweeter placement.

About the Polk Audio DB652 Ultramarine Dynamic Balance Coaxial Speakers

They use Polk's Dynamic Balance technology to deliver full-range sound. They are meant as an upgrade from an OEM speaker system.

The DB+ series is IP55 rated, so it resists dirt and water. It has also been tested for salt fog, UV and humidity. The polypropylene cone is UV tolerant and is built not to discolor or degrade over time. Waterproof inner and outer surrounds keep dirt, liquid and grime out of the speaker housing.

The speakers have a universal fit and drop in to cars, trucks, motorcycles, boats and ATVs. The tweeter is shallow and does not protrude, so a factory speaker grille can be reinstalled for a flush look.

Questions and answers

Do I need an amplifier to run these?
No. At 92 dB sensitivity and 4 ohms they play loud from most head units. An amp gets more from the 100W RMS rating.
Are these actually waterproof?
They are IP55 rated, meaning resistant to water spray and dust, not for submersion. That suits boats and ATVs in normal use.
Will they fit my car?
They need a 5-inch round cutout and 1.77 inches of top-mount depth. Measure your factory opening before buying.
What comes in the box?
The kit includes the DB652 coaxial speakers. Check the listing for grilles and mounting hardware, since contents vary by kit.
How do they compare with component speakers?
Coaxials mount the tweeter over the woofer, which is simpler to install but limits tweeter aiming. Component sets cost more and need separate tweeter placement.
Where is the Polk Audio DB652 Ultramarine Dynamic Balance Coaxial Speakers cheapest?
At Amazon, for $89.00, 18% under what the other stores charge, as of our latest check.
