Introduction

The NuForce S3-BT is an active loudspeaker featuring high-fidelity (apt-X and AAC) Bluetooth wireless connectivity. It’s designed to fit your modern lifestyle and decor while also delivering a level of audiophile quality that many dedicated enthusiasts have longed for-wirelessly.

Bluetooth (BT)enabled devices are now commonplace, but most have always had one weakness – mediocre sound quality. While many BT speakers work well for basic applications, they aren’t able to deliver high-quality sound least not by NuForce standards. That’s because they employ the old and inferior “SBC” codec. In contrast, the NuForce S3-BT is based on the latest “apt-X” codec, which was developed to enable the kind of crystalline sound that NuForce customers have come to expect.

Regardless of how the signal is delivered to it, every speaker is still a speaker at its core, so sound quality always depends on the fundamental principles of speaker design, including the materials used. We kept this in mind when designing the S3-BT, which we built upon a platform of advanced design and superior components. The woofer is constructed using a proprietary anti-resonance” cone technique and powerful magnet assembly, while the tweeter is a custom soft-dome design known among audiophiles for offering the lowest distortion and smoothest natural response.

In its “standard mode,” out-of-the-box form, the S3-BT with apt-X codec offers exceptional Bluetooth performance. Even so, for those hardcore audiophiles who demand the highest level of wireless fidelity, we’ve made the S3-BT upgradeable by including an additional set of analog inputs in the design. This allows the user to bypass the standard Bluetooth connection in favour of using NuForce’s own Air DAC wireless system, or even a wired connection.

The advantage to using the NuForce Air DAC is that it was designed to achieve a level of true 16-bit performance that simply isn’t possible with the Bluetooth standard. As good as Bluetooth with apt-X is, the S3-BT mated with the NuForce Air DAC sounds even better. Whether you choose to use the S3-BT’s “standard mode” Bluetooth wireless or upgrade its sound with the Air DAC system, the S3-BT offers a much-needed, audiophile-grade alternative to mediocre wire-less sound. Don’t settle for less than the best any longer: get the clarity, detail and power all NuForce products are known for, with the NuForce S3-BT.
