Our take on the Alpine W10S4 Bass Line Series 10" 4-Ohm Subwoofer

The Alpine W10S4 is a 10-inch single-voice-coil subwoofer rated at 250W RMS and 750W peak, with a 4-ohm impedance and a polypropylene cone with a poly-foam surround. It plays down to 24Hz and is shallow enough at about 5.1 inches of mounting depth to fit many factory locations. It suits drivers who want solid bass from a modest amp without a big box. Against pricier Alpine Type-R and Type-S subs it gives up excursion and power ceiling, but it needs less power and less airspace.

Pros
  • Runs on a modest 250W RMS amplifier
  • Shallow 5.1-inch mounting depth
  • Plays down to 24Hz
  • Works in a small 0.83 cu. ft. sealed box
  • Polypropylene cone resists moisture
Cons
  • Single 4-ohm voice coil limits wiring options
  • Modest 86.6 dB sensitivity needs real power
  • Not built for high-excursion, high-output bass
  • Peak rating of 750W is brief, not continuous
