Power and Value with Cerwin-Vega H.E.D

Cerwin-Vega's HED series subwoofers, like the HED124, were created with two main goals in mind. To provide quality bass at a great value. Sometimes "value" items aren't as great as they should be and often corners are cut. This is not the case with Cerwin Vega. Their new HED124 subwoofer offers great bass with a power rating of 300 watts peak and 150 watts of continuous RMS, giving you just enough bass that is not overwhelming but still precise. The woofer features a composite polypropylene design that offers the perfect weight to strength ratio that increases the durability of the subwoofer while at the same time improves performance. Its rubber surround allows for high amounts of excursion, while the rolled aluminum former increase thermal capabilities to improve power handling. This means being able to play your subwoofer for longer periods of time. Installation is made easy with the use of nickel-plated pushpin terminals that offer a quick and secure connection every single time. The woofer also features cross-flow window venting that reduces voice coil temperatures and radial contact convex domes that reduce cone flex and minimize distortion. The HED series subwoofers might be a "value" subwoofer but are manufactured and designed to operate at a higher level.
