Name: Alpine - Type-S 15" Dual-Voice-Coil 8-Ohm Subwoofer - Black
Brand: Alpine
SKU: 6901366
Rating: 4 (1 reviews)

Key Specs
- RMS Power: 500 watts (The maximum amount of continuous power the device is able to handle.)
- Peak Power Handling: 1500 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.)
- Minimum Frequency Response: 24 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 0.2 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Sensitivity: 88.7 decibels
- Dual Voice Coils: true
- Woofer Size: 15 inches
- Woofer Composition: Kevlar-Reinforced Pulp Fiber
- Woofer Surround Material: Fiber
