MM1 Series Speakers

Polk MM522

Polk MM522 Two-Way Speakers

It doesn't matter whether your next destination is the road, the lake, the trails or the dunes. Polk's MM1 series speakers are built to not only withstand whatever environment they're thrown into, but to make your ears happy through all of it.

Polk's Mobile Monitor speakers are rugged and built for all kinds of outdoor settings. The IP56 ultra marine certification means all parts - the surround, the cone, the basket and everything else - can withstand dirt, dust and water without any serious side effects. They're ready for your boat, ATV or anything else designed for exposure to the elements. Add in a non-corrosive fiberglass reinforced ABS basket, and these MM1s are ready for the long haul.

Polk MM522 Two-Way Speakers

Not looking for outdoor adventure? These MM1 speakers are still built to outperform your factory drivers in your daily vehicle. Check out that crossover built onto the speaker. While two- or three-way speakers have crossovers mounted on, they're not usually this robust. Add a pivoting 1" tweeter to customize your sound, oversized voice coils and more, and your next drive will sound a whole lot better. Built-in Dynamic Balance Technology helps eradicate distortion and enrich the tone.

Don't put off that sound upgrade any longer. Polk's MM1 series offers a simple solution with anything-but-simple sound. Drop a pair of these in your cart and be prepared for your next adventure.

NVX SDBSK2 Premium Stealth Black

The following review is for SDBSK2, which is a part of the bundle you are viewing.

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.
