Designed to Perform

Introducing the new Mobile Monitor MM1540 high performance 15-inch subwoofer, the biggest and baddest of the MM series! With 425 Watts continuous, 850 Watts peak power handling you'll be heard blocks away. As a result of 3 years of Polk research and development, the new MM systems have been designed to offer unparalleled sound quality with exceptional fit to meet virtually any application. Borrowing technology from our flagship SR Series, the MM Series offers exceptional value for the price. Through the use of high-tech carbon composite baskets, oversized voice coils, and state-of-the-art composite cones, we offer high-end audio performance normally found only in the most expensive loudspeaker systems.

MM1540 Features:

  • New polymer woofer cones and butyl rubber surrounds will not break down over time and will survive the rigors of harsh automotive environments.

  • High temperature copper voice coil (51mm) and polyamide former withstands the most rigorous use while maintaining extremely low distortion for bass punch and output.

  • Nickel plated heavy duty input terminals accommodate speaker wire up to 8 AWG or twisted pairs of 12 AWG.

  • Carbon composite basket based on the spokes of a wheel is lightweight, will not flex during peaks and looks great! Don't be afraid to show off the back of your woofer.

  • Klippel optimized components using a state-of-the-art Klippel distortion analyzer, Polk engineers were able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance, even at extreme listening levels.

  • Available matching grilles complement the wheel spoke design.

  • Dual voice coil configuration (MM1540DVC) also available.
