Our take on the Cadence CMW124S 12" 400W RMS 4-Ohm Car Audio Subwoofer

The Cadence CMW124S is a 12-inch car subwoofer from the Momentum Series with a single 4-ohm voice coil. It handles 400W RMS and 800W peak, and its 91 dB sensitivity means it gets loud on modest amplifier power. A pressed paper cone, butyl rubber surround and oversized magnet are conventional parts at this level, so it competes on output and value rather than exotic materials. It suits a single-sub ported build for a daily driver rather than a competition system.

Pros
  • 91 dB sensitivity makes the most of smaller amplifiers
  • 400W RMS handling is generous for a single 4-ohm sub
  • Butyl rubber surround resists wear better than foam
  • 10mm Xmax gives decent excursion for deep hits
  • Ported box spec is published, so enclosure planning is simple
Cons
  • Single 4-ohm coil limits wiring options to one final load
  • Pressed paper cone is less rigid than poly or composite cones
  • Needs a ported box to perform at its best
  • No dual voice coil version for flexible impedance

Questions and answers

What amplifier power does the CMW124S need?
It is rated at 400W RMS and 800W peak with a single 4-ohm voice coil. Match it to a mono amp that makes around 400W into 4 ohms, and set gain so the sub is not driven past RMS.
What size box does it work best in?
Cadence specifies a 0.9 cu ft ported enclosure with a 4-inch diameter port 8.89 inches long. Build to that spec for tight, responsive bass rather than a sealed box.
Is it a dual voice coil sub?
No. It uses a single 4-ohm voice coil, so one sub presents a 4-ohm load to the amp. Two of them in parallel drop to 2 ohms, so check your amp is stable there.
What is in the box?
One CMW124S 12-inch subwoofer and a user manual. Mounting hardware and an enclosure are not included.
Can it handle deep bass without distortion?
With 10mm Xmax and 91 dB sensitivity it moves a fair amount of air for its power rating. Keep it within 400W RMS in the recommended ported box and it stays clean.
Is it worth it over a dual voice coil sub?
If your amp is happiest at 4 ohms, the single coil is simpler and avoids wiring mistakes. If you want to run multiple subs at different loads, a dual voice coil model gives more flexibility.
