Eminence Hi-Fi Woofer 840SF 8" Paper Cone - Foam Surround 8 ohm - 2" Voice Coil 40oz Vented Magnet 175 Watts RMS / 350 Watts Peak Frequency Range: 28hz - 4.5khz Sensitivity: 91dB @ 1 Watt / 1 Meter Frame Outside Diameter: 8.25" Cabinet Cutout Diameter: 7" Part # 01-156 The Eminence Hi-Fi woofers are an excellent choice for home audio. They are very efficient and do not require much power (although they can handle alot of power.) Eminence rates their woofers all the way down to 1 watt. This means you can play the woofers with as little as 1 watt of power and they will still sound fine. Some home audio tube amps only have 10-15 watts of power. These woofers will still work perfect at this low power!
