The Infinity REF1050W is a 10” single voice coil subwoofer composed out of a high-efficiency polypropylene woofer cone that is lightweight and geared to produce a higher sound output. An upgrade from the REF850W, the REF1050W offers an increased nominal power handling of 250w (versus 200w), an improved peak power handling of 1000w (versus 800w), and a superior frequency of 25Hz-400Hz (versus 30Hz-400Hz). The REF1050W, however, maintains the REF850W’s 4 ohms impedance, 2” voice-coil, and 91dB sensitivity @ 2.83V/1m. In addition, the REF1050W features large-roll rubber surrounds, an in-board motor structure, and vented polepieces. Priced at $69.99, the Infinity REF1050W is exactly $5 more expensive than the weaker REF850W.
