Combining bass quality and bass quantity with high power, along with installation flexibility that provides high performance in both acoustic suspension (sealed) and bass reflex (ported) enclosures, the D subwoofer is the ultimate all-around performer. Experience the slam, attack, and power of your music – don’t just listen to it, feel it.

Butyl Rubber Surround:

• Crafted from a specially blended, highly durable, and moisture-resistant compound, the butyl rubber surround ensures the cone moves in a linear direction. It seals the cone to the basket and rapidly dampens cone vibration once the signal changes or stops, resulting in reduced distortion and superior frequency response.

Aramid Fiber Interlaced Injection Molded Polypropylene (IMPP):

• Polypropylene (PP) is an excellent material for subwoofer cones due to its low mass and high damping, offering good sensitivity and low distortion. However, it lacks the required rigidity and strength for high output and extreme low bass. Pioneer engineers addressed this by blending aramid fibers into the polypropylene resin during the injection molding process. The resulting Aramid Fiber Interlaced IMPP subwoofer cone is incredibly strong, low mass, and rigid, delivering deep, powerful, and undistorted bass.

Large Diameter Voice Coil and Double Stacked Magnets:

• The subwoofer motor structure comprises the voice coil and magnet assembly. Increasing the diameter and length of the voice coil provides greater control over the woofer cone and higher power handling. To fully capitalize on this, the magnet must also be enlarged in magnetic power and physical size. The D subwoofer utilizes an oversized 4-layer voice coil and high-energy double stacked magnets, boosting overall power handling and SPL output without compromising sound quality.
