SW 10 specifications

The NHT SW 10 is a well-regarded subwoofer that has gained a reputation among audiophiles for its impressive performance and deep, rich bass response. Designed to complement both music and home theater systems, this subwoofer combines technology and quality craftsmanship to provide an immersive listening experience.

One of the standout features of the SW 10 is its powerful 10-inch driver, which is specifically engineered to produce low-frequency sounds with precision and clarity. The driver is constructed using high-quality materials to ensure durability and long-lasting performance. In addition to the driver, the SW 10 is equipped with a built-in high-efficiency amplifier that delivers up to 200 watts of peak power. This ensures that the subwoofer can handle dynamic soundtracks and bass-heavy music without distortion, contributing to its overall performance.

Another notable characteristic of the NHT SW 10 is its adjustable low-pass filter, which allows users to fine-tune the crossover frequency. This feature enables seamless integration with satellite speakers, ensuring that the subwoofer complements the overall sound profile of the audio system. Furthermore, the phase control switch allows for precise alignment with other speakers, enhancing the overall soundstage and tonal balance.

The acoustic design of the SW 10 also plays a significant role in its performance. It features a bass reflex enclosure that uses a ported design to maximize airflow and increase bass efficiency. This design not only enhances low-frequency output but also ensures that the subwoofer produces tight and controlled bass, rather than muddy or boomy sounds.

Connectivity options are another strength of the NHT SW 10. It is equipped with both line-level and speaker-level inputs, making it compatible with a wide variety of audio systems. Users can easily integrate it into existing setups, whether they are using it with a stereo or home theater configuration.

With its sleek and modern aesthetic, the NHT SW 10 can blend seamlessly into any room decor. Its compact design makes it easy to place, whether in a corner of the room or discreetly tucked away. Overall, the NHT SW 10 stands out as an excellent choice for those seeking a high-quality subwoofer that delivers an extraordinary listening experience.
