Placement

Note: To prevent the Ten and Twelve subwoofer amplifi- er from overheating, always be sure to provide adequate space for proper ventilation. Do not place the subwoofer directly against the wall or any other surface.

The key to placing your subwoofer for optimal enjoyment is to remember that low frequencies produce sounds with long wavelengths, which interact in complex ways with room boundaries, such a walls and corners, and other large objects as well.

Placing the subwoofer near to a room boundary will tend to increase its apparent bass output, but may result in "boomy" or "muddy" sound. Conversely, placing it farther away from room boundaries will tend to decrease its apparent bass output, but may result in improved articulation and clarity.

When possible, place the subwoofer in the same horizontal plane and along the same wall as the main speakers.

And since small changes in subwoofer position can have a significant effect on sound, experimenting with the effects of different placements in your own listening/view- ing room is the key to finding the sound you like best.

Ten and Twelve Features & Controls

Volume: This control allows you to adjust the gain of the Subwoofer relative to the rest of your system. Many lis- teners make the mistake of setting subwoofers too loud, which can cause excess bloat and loss of detail and musicality. A properly calibrated subwoofer blends in with the speakers and does not call attention to itself. To properly set volume:

•Turn down the volume control on the Ten and Twelve to its lowest position (counter-clockwise).

•Turn on your audio system, including the Ten orTwelve. Play some music you are familiar with and set your receiver/preamplifier volume to a comfortable listening level.

•Slowly increase the volume of the Ten or Twelve, lis- tening for proper frequency balance. When balanced, you will hear improved bass extension, but not be aware that it is coming from the subwoofer.

From this point on, the volume control on your receiver/preamplifier will control the overall volume of your system, including the subwoofer.

The Boundary EQ: This is a feature unique to NHT products. Reflective boundaries (such as walls) rein- force a speaker’s bass output (3dB for two walls, 6dB for a corner) if the subwoofer is placed near them. Conversely, placing a subwoofer out in the room results in a relative decrease in bass output. Boundary rein-

NHT (New Technology HiFi) powered subwoofers are renowned for their ability to provide deep, rich bass that complements any audio setup. As part of a complete home theater or music system, NHT subwoofers are designed to deliver precise sound reproduction with minimal distortion, enhancing overall listening experiences.

One of the notable features of NHT powered subwoofers is their built-in amplification. Unlike passive subwoofers that require an external amplifier, NHT subwoofers come equipped with high-quality, integrated amplifiers that are specifically tuned to match the driver components. This ensures optimal performance and efficient power usage, eliminating the need for additional equipment and simplifying setup.

NHT utilizes advanced driver technology in its subwoofers. The proprietary woofers are engineered for exceptional linearity and dynamic range, providing deep bass frequencies while remaining clear and undistorted even at higher volumes. This attention to detail in driver design allows NHT subwoofers to reproduce low-end frequencies with incredible accuracy, making them ideal for both music and cinematic soundtracks.

Another critical aspect of NHT powered subwoofers is their versatility in adjusting performance to fit individual preferences and room acoustics. Many models feature adjustable volume controls, phase controls, and low-pass filters. This allows users to customize the sound output to match the characteristics of their listening environment, whether it’s a small room or a larger home theater setup.

NHT subwoofers are also designed with aesthetic considerations in mind. They typically feature sleek, modern finishes that integrate seamlessly into various home decor styles. This design philosophy ensures that consumers do not have to compromise on aesthetics while enjoying high-quality audio performance.

Connectivity options are extensive in NHT powered subwoofers, accommodating various setups. They often include both line-level RCA inputs for traditional audio sources and high-level speaker inputs for connection to home theater receivers. This flexibility enhances their compatibility with a range of audio components.

Overall, NHT powered subwoofers embody a blend of innovative technology, user-friendly features, and aesthetic appeal. They offer music and movie enthusiasts the powerful bass response needed for immersive audio experiences, making them a solid choice for anyone looking to enhance their sound systems with superior low-frequency performance. With their emphasis on quality and performance, NHT subwoofers continue to be a popular selection among audiophiles and home theater enthusiasts alike.
