Introducing the new MM840 high performance 8" subwoofer. Great for big bass without taking up much space.
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,
powerful Neodymium motor structures using oversized voice coils, and
state-of-the-art woven glass composite cones, we offer high-end audio
performance normally found only in the most expensive loudspeaker
systems.
With 250 watt continuous/500 watt peak power handling, the MM840 is recommended for small sealed (.35 cubic foot) enclosures.
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.
Heavy Duty Input Terminals accommodate speaker
wire up to 8 AWG or twisted pairs of 12 AWG.
Advanced 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 Grille complement the wheel spoke design.
Dual Voice Coil Configuration (MM840 DVC) also available.
