about the same frequency you have set the High Pass Filter. For example, if the High Pass Filter sends only signals above 75Hz to your main speakers, begin with the Low Pass Filter set at 75Hz. See the “Fine Tuning” section for further adjustment guidelines.

If you are using Connection Method #2 or #4, your main speakers are reproducing the entire frequency range (including bass) and it is advantageous for the subwoofer to reproduce only those frequencies below the rated response of the main speakers. For example, if your main speakers have a rated low frequency response of 60Hz, begin with the Low-Pass Filter set at 60Hz. See the “Fine Tuning” section for further adjustment guide- lines.

If you are using Connection Method #3, your main speakers are reproducing only frequencies above 100Hz, due to the fixed 100Hz high pass filter at the speaker-level output barrier strip. As a starting point, set the Low Pass Filter at 100Hz. See the “Fine Tuning” section for further adjustment guidelines.

The selectable HIGH PASS FILTER determines the range of frequencies that the main speakers (“satellites”) will reproduce. For example, a high pass setting of 50Hz means that the main speakers receive a signal con- taining only frequencies above 50Hz. The benefit of high pass filtering is improved dynamic range and lower distortion in the main speakers, as they are spared the task of low frequency reproduction. There are three available high pass settings: 50Hz, 75Hz and 110Hz.

The High Pass Filter should initially be set to a frequency above the rated low frequency limit of the main speak- ers. For example, if your speakers have a rated low frequency response of 40Hz, use the 50Hz high-pass set- ting. If your speakers have a rated low frequency response of 90Hz, use the 110Hz high-pass setting.

To select the appropriate high pass setting for your main speakers, check the owner’s manual for their rated low frequency response. If you are unable to obtain this information, here are some common high-pass settings:

 

Small speaker

 

 

 

Large speaker

 

 

 

Medium speaker

 

 

110Hz

 

75Hz

 

50Hz

 

 

 

 

 

 

 

 

The SUBWOOFER PHASE selector sets the phase of the subwoofer at the 0° position (normal phase) and the 180° position (reverse phase). The ability to adjust subwoofer phase is a great advantage for achieving smooth bass response in your system. The combined low frequency sound waves from the subwoofer and the main speakers can sometimes cause peaks and dips in the frequency response at the listening position. In these cases, adjusting the subwoofer phase may improve the blending and overall performance of the system.

The optimal phase setting will differ according to room conditions and placement, and the main speakers used. Experiment with phase settings by listening to a familiar CD from the listening seat, alternating phase settings on the same track. Do not attempt to evaluate the best sound while standing above the subwoofer or amplifi- er, as the sound at the listening position will be significantly different.

The SUBWOOFER GAIN switch allows you to attenuate the line-level input sensitivity of the SubOne i by 10dB. This is useful if your receiver or preamplifier has very high line-level output voltage that limits your range of vol- ume adjustability on the SubOne i Controller. Engaging the 0dB attenuation will give you a wider range of vol- ume adjustment for the SubOne i.

The SubOne i has a STANDBY MODE feature that is automatic and requires no user adjustment. When no signal is present for 45 minutes, the SubOne i goes into Standby Mode, and it will use a minimum of power to remain “asleep.” When the system is used again, it immediately turns on as soon as a signal is received. There is no need to turn the SubOne i on and off every time it is used.

SubOne i specifications

The NHT SubOne i is a remarkable subwoofer that combines cutting-edge technology with high-performance sound engineering, making it an exceptional choice for audiophiles and home theater enthusiasts alike. Designed to deliver deep, powerful bass while maintaining clarity, the SubOne i elevates any audio experience, whether it be music, movies, or gaming.

One of the main features of the NHT SubOne i is its innovative driver design. It utilizes a 10-inch high-excursion woofer that provides an expansive low-frequency response down to 28Hz. This feature ensures that listeners feel the full depth of sound, from the rumble of thunder to the subtle details of a bass guitar. The woofer's advanced materials and construction allow for precise movements, resulting in low distortion and high output levels.

Complementing the driver is an advanced Class D amplifier that delivers 300 watts of continuous power and peaks at 600 watts. This efficient amplification means that the SubOne i can easily handle dynamic soundtracks, ensuring that every crash and explosion in movies comes through with breathtaking intensity. Notably, the amplifier is also designed to monitor the woofer's performance, adapting in real-time to prevent clipping and distortion.

Versatility is another hallmark of the NHT SubOne i. It provides multiple connectivity options, including both RCA and LFE inputs, ensuring compatibility with a variety of audio sources, from AV receivers to music systems. A built-in crossover allows users to adjust the subwoofer's frequency response, tailoring the audio output to match their specific needs and room acoustics. This feature also offers phased adjustment for seamless integration with satellite speakers.

Moreover, the SubOne i features a sleek, modern design with a robust cabinet construction that minimizes resonance, thereby enhancing sound quality. The enclosure is strategically designed to reduce vibrations, resulting in a tighter, more controlled bass response.

In terms of usability, the NHT SubOne i is designed with user-friendly controls located on the rear panel. Users can easily adjust volume, phase, and crossover settings for quick and intuitive customization.

With its powerful performance, advanced technologies, and exceptional build quality, the NHT SubOne i stands out as a premier choice for those seeking to enhance their listening experience. Whether for a professional-grade home theater system or a high-fidelity music setup, the SubOne i is sure to impress, providing deep, rich bass that transforms any space into an immersive auditory haven.
