MS-10SD4, MS-10SD2, MS-12SD2, MS-15SD2, MS-12SD4 specifications

The Harman MS series of subwoofers, which includes the MS-10SD2, MS-12SD4, MS-12SD2, MS-15SD2, and MS-10SD4, is designed to deliver powerful bass performance and exceptional sound quality. Each model is engineered with advanced technology and features to meet the needs of audiophiles and casual listeners alike.

The MS-10SD2 is a 10-inch subwoofer that boasts a dual 2-ohm voice coil configuration. Its robust construction includes a polypropylene cone, which provides durability and effective sound reproduction. The subwoofer can handle up to 300 watts of RMS power, making it suitable for a variety of applications, including home theater and car audio systems. Harman's patented Progressive Piston Design offers better linearity, reducing distortion at higher volumes.

The larger MS-12SD4 features a 12-inch cone and a dual 4-ohm voice coil setup. This subwoofer is designed to deliver deeper bass tones and can handle up to 400 watts of RMS power. The advanced venting system helps to keep the voice coil cool, which enhances performance and longevity. With its stiff cone and strong surround, the MS-12SD4 provides an impactful audio experience that can fill any space.

Similar to the MS-12SD4, the MS-12SD2 also features a 12-inch cone but utilizes a dual 2-ohm voice coil configuration. This model is optimized for a balance between power handling and efficiency, allowing it to deliver clear and dynamic bass tones even at high volume levels. The high-temperature voice coil ensures that performance remains consistent, even during extended use.

For those looking for even more power, the MS-15SD2 is a remarkable 15-inch subwoofer that features a dual 2-ohm voice coil. It can handle an impressive 600 watts of RMS power, making it one of the most robust options within the MS series. This model is designed for high-efficiency performance, ensuring that it can produce deep, resonant bass that enhances the overall sound stage.

Lastly, the MS-10SD4 is another 10-inch subwoofer variant that comes equipped with a dual 4-ohm voice coil. Like its counterparts, it prioritizes sound quality and durability with features such as a reinforced cone structure and a progressive suspension design. This model is ideal for those seeking a compact yet powerful subwoofer that does not sacrifice bass performance.

In summary, the Harman MS series of subwoofers offers a range of options catering to different preferences regarding size, power handling, and impedance configurations. Each model integrates advanced technologies and features to ensure that users can enjoy potent, clear, and high-quality bass regardless of the application.
