- Polypropylene Cone A durable plastic-based material which exhibits low mass for good transient response, rigid structural integrity for low distortion, and high internal loss for accurate sound reproduction without excessive "ringing". Withstands the extremes of the autosound environment well.
- Dual Spider Employs two spiders for superior control at maintaining the voice coil in the center of the magnetic field.
- Rubber Surround Offers superior compliance and durability compared to foam. Additionally, rubber tends to hold it's original shape better than other materials.
- Parabolic Contour Pole and Plate Focus's magnetic energy inward toward the voice coil resulting in superior magnetic strength from a smaller magnet.
- Gold Plated Binding Posts Wire connection terminals with 5 different attachment schemes for easy hookups. Gold offers superior resistance against corrosion.
- Aluminum Die-cast Basket Offers superior rigidity to steel along with lower weight and lower resonance, resulting in lower distortion and cleaner sound reproduction.
- Frequency Response 450W(max input)/20Hz-30kHz, ±10dB
- Impedance 88dB/W/M/4Ohms
- Subwoofers are usually sold as a single unit unless otherwise noted.
