Name: Alpine - Type-R 10" Dual-Voice-Coil 8-Ohm Subwoofer - Black
Brand: Alpine
SKU: 6893811
Rating: 4.3 (3 reviews)

Key Specs
- RMS Power: 1000 watts (The maximum amount of continuous power the device is able to handle.)
- Peak Power Handling: 3000 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
- Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
- Dual Voice Coils: true
- Woofer Size: 10 inches
- Woofer Surround Material: Santoprene

Enjoy crisp, powerful bass while you drive with this Alpine Type-R SWR-10D4 10" subwoofer that features an H.A.M.R. (High Amplitude Multi-Roll) surround design and a CRC (Compound Radius Curve) motor structure for enhanced linear excursion.

Handles up to 3000W peak power (1000W RMS): For rich, powerful sound.
26-200Hz frequency response: Along with 82.1dB sensitivity for accurate sound reproduction.
Reinforced parabolic cone structure: With a poly-mica dust cap and DuPont™ KEVLAR® fiber-pulp body for a lush soundscape.
8 ohms impedance: Conducts power evenly to keep the speaker at an appropriate level.
H.A.M.R. (High Amplitude Multi-Roll) surround design: With injection-molded Santoprene rubber allows more than 20mm linear excursion.
CRC (Compound Radius Curve) motor structure: Creates a symmetrical magnetic field while optimizing flux density for distortion reduction.
Radial-vented VC heat-sink and airflow management system: Helps minimize power compression and ensures reliably long playing time by wicking heat away from the voice coil.
