tings on the same track. Do not attempt to evaluate the best sound while standing above the subwoofer or amplifier, as the sound at the listening position will be significantly different.

„Subwoofer Volume Control

The SA-2’s front panel VOLUME CONTROL allows you to adjust the volume of the subwoofer relative to the rest of the system. Many listeners make the mistake of setting subwoofers too loud, which can cause excess bloat and loss of detail and musicality. A properly cal- ibrated subwoofer blends in with the speakers and does not call attention to itself. Observe the following guidelines for volume setting:

Turn down the volume control of the SA-2 to its lowest position (counter-clockwise). Turn on your system, including the SA-2. Play some music you are familiar with and set your receiver/preamplifier volume to a comfortable listening level. Slowly increase the volume on the SA-2, listening for proper frequency balance. When the subwoofer output is balanced with the rest of the system, you will hear improved bass extension, but you should be unaware 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 SA-2 and SW2Si: The SW2Pi Powered Subwoofer System

A subwoofer’s performance in the context of your audio / video system is highly dependent upon its interaction with your front L & R 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 possible 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. To help you determine the best way to connect the sub- woofer to your system, consider the following suggestions:

1.If you have large (full-range) L & R speakers... 1st Choice: Method #2 (SA-2 connected at line level with high-pass filter loop) 2nd Choice: Method #1 (SA-2 connected at line level, no high-pass filter)

3rd Choice: Method #4 (SA-2 connected at speaker level, no high-pass filter)

If your L & R speakers have generous bass response and you are adding a subwoofer, you have the option of sending the speakers a high-pass filtered signal (Method #2). With the low bass information removed from the signal before it reaches the speakers, all low fre- quencies are reproduced exclusively by the subwoofer. With this configuration it is usually easier to achieve smooth low frequency response, as the subwoofer reproduces a different frequency range than the speakers. Use the 50Hz high-pass setting.

If you want to run the L & R speakers full-range, or if you have a receiver with no “Pre-Out” and “Main-In” (see “What connection meth- ods are available?” below), you can run the L & R speakers full range and use the subwoofer only to provide low bass reinforcement (Connection Methods #1 and #4). Sending the speakers a full-range signal can sometimes make it difficult to integrate them with the subwoofer, as their combined low frequency output can cause irregularities (peaks and dips) in the room’s low frequency response. In this case, the subwoofer’s low-pass setting should be quite low and used only to fill in the lowest octave.

Method #3 is not recommended with large L & R speakers.

2.If you have small (bookshelf) L & R speakers... 1st Choice: Method #2 (SA-2 connected at line level with high-pass filter loop) 2nd Choice: Method #3 (SA-2 connected at speaker level with fixed high-pass filter)

If your L & R speakers are smaller bookshelf-type models with limited bass response, it is advisable to send them a high-pass filtered signal (Method #2 or #3). With the low bass information removed from the signal before it reaches the speakers, all low frequencies are reproduced exclusively by the subwoofer. The L & R speakers exhibit reduced distortion, greater dynamic range and power handling, because they receive a signal containing only information that falls within their specified frequency response range. Use the 75Hz or 110Hz high-pass setting.

Alternately, you can run the speakers full range and use the subwoofer to reproduce all the low bass frequencies below their response capabilities (Methods #1 and 4). While simple, this configuration does not remove the burden of low frequencies from the L & R speakers and may limit their output at higher volumes.

3. What connection options are available?

a)If you are using a separate preamplifier and main amplifier, all of the connection methods are available to you.

b)If you are using an integrated amplifier or receiver (hereafter called “receiver”) with “Pre-Out” and “Main-In” jacks, all of the connec- tion methods are available to you.

c)If you are using a receiver with “Pre-Out”, “Line Out’ or “Subwoofer Out” jacks but no “Main-In” jacks, you may use Methods #1, #3 or #4.

d)If you are using a receiver with no “Pre-Out”, “Line Out” or “Subwoofer Out” jacks, you may use Methods #3 or #4.

SA-2 specifications

The NHT SA-2 is a remarkable achievement in the world of audio engineering, representing a synthesis of innovative design, advanced technology, and exceptional acoustic performance. Launched by NHT (Next High Technology), a company renowned for its commitment to high-fidelity audio reproduction, the SA-2 stands out for both its aesthetic appeal and high-performance specifications.

One of the standout features of the NHT SA-2 is its compact design, making it suitable for a variety of listening environments. This speaker is engineered to deliver a full-range sound experience despite its smaller footprint. The SA-2 utilizes a proprietary 5.25-inch woofer that is designed to produce deep and rich bass tones, complemented by a 1-inch silk dome tweeter that excels in handling high frequencies. This combination allows the SA-2 to reproduce a broad dynamic range, ensuring that listeners can experience their music with clarity and detail.

In terms of technology, the NHT SA-2 leverages advanced materials and construction techniques to enhance performance. The woofer cone is formed from a specially engineered composite material that offers both rigidity and lightweight properties. This helps to minimize distortion and ensures that sound waves are produced accurately. Additionally, the tweeter's silk dome design contributes to a smooth frequency response, reducing harshness and delivering a more natural sound.

Another noteworthy characteristic of the NHT SA-2 is its versatility. It is designed for both two-channel stereo setups and can easily integrate into multi-channel home theater systems. The speaker can be used in various configurations, whether as part of a dedicated music listening space or in a surround sound setup, making it a flexible choice for audiophiles and casual listeners alike.

The SA-2 also benefits from thoughtful engineering. Its rear-firing port enhances bass response, allowing for greater low-frequency extension without requiring excessive cabinet size. This design choice enables it to adapt well in different room environments, further enhancing its usability.

Overall, the NHT SA-2 embodies the core principles of high-quality audio reproduction. With its advanced construction, thoughtful engineering, and versatile application, it is an excellent choice for anyone looking to elevate their listening experience.
