Buy your CMP S3-12D.5N Neodymium Subwoofer

High quality precision

The extremely rigid, mica-reinforced cone delivers uncompromising performance for optimal control and precision, even at the highest pressures. In addition, a custom-made carbon dust cover protects this monster's 8,000W RMS and eliminates any cone distortion. The result: a subwoofer of extreme rigidity, unmatched control, and exceptional precision.

World-class endurance

At this ultimate level, linearity and precision are essential. A moving assembly with an elite cone and a top-notch American-made voice coil (80 mm winding height) must remain perfectly aligned, even during extreme travel. To tame this imposing moving mass, we incorporated a 4-layer Nomex winding with orange mesh, as well as an ultra-resistant foam surround at the top, of course double-stitched to the cone.

Extreme Power Management

A dual 4-inch, 8-layer black anodized flat aluminum wire voice coil gives the CMP S3-12D1N and CMP S3-12D.5N excellent power handling and heat dissipation. They are available in two versions, 1+1 or 0.5+0.5 ohm, for perfect impedance matching to your amplifiers. For optimal signal transfer and increased durability, double silver-plated metal wires have been sewn into the housing. The pre-connected 10 mm² oxygen-free copper direct wires provide excellent conductivity for a solid and reliable direct connection between the subwoofer voice coil and your amplifier, without resistance points or poor contact.

Elite performance

This subwoofer was designed from the ground up for extreme conditions. The high-quality 16-block N52 neodymium driver delivers unmatched power control over the massive 80mm X-max driver for unmatched performance. Additionally, the precisely arranged open-cooling system with neo-blocks ensures optimal performance, even in the most intense competitions. The CMP S3-12D1N and S3-12D.5N require a lot of space and attention, but will reward you with unmatched bass.
