Placement, Four Connection Methods | NHT SubOne i instruction

!Placement

Experimentation is the key to finding the best location for the SubOne i in your listening environment. When possible, place the subwoofer in the same horizontal plane and along the same wall as the main speakes. Low frequencies produce long wavelengths and thus interact with room boundaries significantly. Placing the sub- woofer nearer to a room boundary (walls, corners) will tend to increase its bass output, but may result in “boomy” or “muddy” sound. Conversely, placing the subwoofer farther away from room boundaries will tend to decrease its bass output, but may result in improved articulation and clarity.

Note: To prevent the SubOne i subwoofer amplifier from overheating, always be sure to provide ade- quate space for proper ventilation. Do not place the subwoofer directly against the wall or any other sur- face.

Position the subwoofer so that it does not radiate sound directly into a wall or floor, and ensure that it faces into the room, unobstructed by large furnishings. If you are using two subwoofers, the greatest improvement in low frequency response is usually achieved by placing the second subwoofer asymetrically on the oppostite side of the room from the first. For example, if one sub is placed in the front left corner of the room, the second should be placed along the front (same) wall about 1/3 of the way into the room from the right corner. Avoid placing two subwoofers symmetrically (such as in two corners), as it will tend to exaggertate standing waves. As the SubOne i is not shielded, do not place it in close proximity to a television, or picture discoloration will occur.

The SubOne i Controller is most conveniently placed in a rack with other equipment, although it may also be placed on top of the subwoofer.

!Four Connection Methods

Caution: Prior to connecting the SubOne i to your audio system, it is important that all AC power con- nections to associated components (receivers, amplifiers, preamplifiers, processors, etc.) are either unplugged or turned off. Do not plug in or connect the SubOne i subwoofer to AC power until all connections have been made.

The SubOne i subwoofer and Controller are connected via a single 20-foot-long RCA cable. The subwoofer is plugged directly into an AC outlet in the wall. The SubOne i Controller receives power via the LL1 15VAC Power Supply. If the distance between the subwoofer and Controller in your room is greater than 20 feet, your NHT dealer offers RCA cables in varying lengths.

A subwoofer’s performance in the context of your audio / video system is highly dependent upon its interaction with your main (largest) speakers. Since a subwoofer is designed only to provide low frequency response, it is important to connect it in a manner that ensures seamless integration with your speakers. There are four pos- sible connection methods outlined in this manual. The best method for you depends on the size of your front L & R speakers and the connection options available on your receiver or preamplifier (see next section). To help you determine the best way to connect the subwoofer to your system, consider the following suggestions:

1. If you have large (full-range) main speakers...

1st Choice: Method #1 (line-level with or without LFE connection with high pass filter loop)

2nd Choice: Method #2 (line-level and/or LFE input connection with no high pass filter loop)

3rd Choice: Method #4 (speaker-level connection with no high pass filter loop)

If your main speakers have generous bass response and you are adding a subwoofer, the resulting sound could be “muddy.” You have the option of sending the main speakers a high-pass filtered signal (Method #1). With the low bass information removed from the signal before it reaches the speakers, all low frequencies are repro- duced exclusively by the subwoofer. With this configuration it is usually easier to achieve smooth low frequen- cy response, as the subwoofer reproduces a different frequency range than the speakers. Use the 50Hz high pass setting.

If you want to run the main speakers full-range, or if you have a receiver with no “Pre-Out” and “Main-	4
In” (see next section), you can use the subwoofer only to provide low bass reinforcement (Connection

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.
