NHT Powered Subwoofers owner manual Two tips on using the Low Pass Filter

forcement may lead to low frequency response that is uneven. Some frequencies will sound exaggerated rela- tive to others, or the subwoofer will sound thin and lack impact. The Boundary EQ control allows you to com- pensate for the effects of room boundaries on the fre- quency response of the subwoofer. Adjusting the control enables you to achieve smooth low frequency output from the subwoofer regardless of its location in your room.

The following diagrams shown in Fig. 1 show the corre- lation between subwoofer placement and Boundary EQ. These diagrams are guidelines only. Your room acoustics and personal tastes will ultimately dictate the final setting.

LOW PASS FILTER: This control determines the upper- limit frequency the subwoofer will reproduce. For example, setting the filter at 100Hz will cause the subwoofer to reproduce only frequencies below 100Hz. The Low Pass Filter is continuously variable between 40Hz (low bass) and 180Hz (upper bass), to accommodate different speakers.

Two tips on using the Low Pass Filter:

As a starting point, set Low Pass Filter to the 1 o’clock position. This will result in an 80Hz low pass. As the set- ting is typical for most Dolby Digital / DTS applications. Note: The LFE input bypasses the adjustable 12dB Low Pass Filter.

See the Fine-Tuning section for further adjustment guidelines.

SUBWOOFER PHASE: This switch sets the phase of the subwoofer at either the 0° position (normal phase) or the 180° position (reverse phase) to achieve the smoothest possible bass response in your system.

This phase-reversing option is important because if bass frequencies come from both the subwoofer and the main speakers, peaks and dips in the frequency response can occur at the listening position. In these cases, reversing the subwoofer phase can improve blending and balance.

To properly set the Subwoofer Phase:

Play familiar music, reversing phase settings. And listen from your usual position.

Avoid evaluating while standing above the subwoofer or

amplifier; sound at the listening position will be significantly different.

The correct setting is the one in which the bass is the loudest at the listening position.

POWER MODE: This feature automatically switches your Ten or Twelve into minimum-power mode (ie, sleep) whenever no signal is present for 20 minutes. When a signal is received, it immediately turns on again. As AUTO Mode is automatic, it requires no adjustment, nor is there a need to turn the Ten or Twelve on and off every time it is used. When in ON Mode, the subwoofer is always on.

Powered Subwoofers specifications

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.
