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.

Nice Wiring Kit

The following review is for SDSK2, which is a part of the bundle you are viewing.

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

Works pretty good

The following review is for SDSK2, which is a part of the bundle you are viewing.

I bought this product for my trucks doors, and I noticed it's thicker than other sound dampening material I've used before that I paid a lot more for. This is a great product at a great price

Easy to use, good performance!

The following review is for SDSK2, which is a part of the bundle you are viewing.

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

The following review is for SDSK2, which is a part of the bundle you are viewing.

Very nice sound dampening material easy to install and gives a great added depth to the sound of yr system, deeper bass and mids and also minimizes the resonance of the factory locations

Nvx = quality at the best price.

The following review is for SDSK2, which is a part of the bundle you are viewing.

I'm so happy with all my NVX products. They are always the best in quality and price. No smell and if it's not a lot you can apply it without a roller. (I used my hands and the back of a screw driver to really smooth it out)
