Sunfire HRS10 10 Inch High Resolution Series Subwoofer - 10 Inches. 1000 Watts. Countless Hours of Enjoyment. If your subwoofer puts out less than 1000 Watts its not an HRS Series subwoofer. And all HRS subwoofers produce this prodigious sound in a cabinet no larger than the size of your monitor. If thats still not enough - the amplifier in all three HRS models incorporates Sunfires unique Tracking Downconverter™ technology. Remarkably this amp design remains incredibly cool while delivering up to 50% more voltage than our competitors designs. More voltage means more control of the subwoofer itself. And more control means deeper more accurate bass something youll truly appreciate every time you listen to your favorite music and movies. For medium-sized and multi-purpose rooms where both music and movies are just what the doctor ordered theres no better choice than the HRS-10.
