A solid foundation

Of course, Nuforce knows that careful speaker design is essential, regardless of the source you're listening to. Each S3-BT speaker has a 1" silk dome tweeter for crystal-clear highs and a 3-1/2" woofer for clean, musical mids and bass. The system is driven by a built-in 18-watt x 2 Class D amplifier — plenty of power to get your tunes cranking.

Nuforce S3-BT with Air DAC uWireless

Add a Nuforce Air DAC Wireless system (right), and you can stream music via Wi-Fi as well as Bluetooth.

Wired and Wi-Fi® options

A line-level RCA stereo input lets you connect another source, like a CD player or standalone DAC. (You could even connect your computer, using a stereo mini to RCA adapter.) The system also pairs up nicely with the Apple iOS® and USB versions of Nuforce's Air DAC system, which give you even higher-fidelity wireless 16-bit audio signal transfer. Just connect the Air DAC receiver to the speaker system via an RCA stereo cable.

Common BT problem

NickG from Charlotte NC on 11/8/2014

Crutchfield Customer Review (What's this?)

Check the reviews on other sites - common problem with these is with the bluetooth connection just dying. Mine worked for about 2 weeks, then the same thing; connect BT, start playing for about 2 seconds and then a loud buzzing sound comes from the speakers that doesn't go away unless you turn off/unplug the speakers. I'm 30-days in on my purchase today, I intend on returning

Pros: Sound quality was good while it lasted

Cons: BT problem described.

D Bragg from Jackson, MS on 9/14/2014

Crutchfield Customer Review (What's this?)

Very happy with my purchase, surprised with the base from such a small package. These speakers seem to be well made and have a substantial weight for the size. Sound great!

Pros: Sound is very good, power is strong for the size, looks hi-end.

Cons: Have to re-sink Bluetooth each time you power up the system. Not a big deal.

Solid Bluetooth speakers but not quite perfect

DaveO from Tawas, MI on 7/25/2014

Crutchfield Customer Review (What's this?)

I'm using these in my bedroom with the Bluetooth feature and have not had any issues with the connection. These replaced a fairly high end iPod dock that had great sound but suffered form cabinet buzz/vibration on deep bass tracks. The bass on these is a little limited compared to the dock but the vibrations are gone making for a better listening experience. These have very clear highs and an overall warm and detailed sound. My one mark against these is that they are lacking somewhat in the midrange, which sound a little dull towards the upper end, though as I've used them more this seems to have improved somewhat.

Pros: Well built; Overall very good response for such small speakers; Bluetooth works well and setup is very easy.

Cons: A little dull sounding in the mid-range. Lacks a remote.

Great sound easy to use easy to set up was a great gift



Bluetooth does not work

DE from Palo Alto, CA on 9/27/2013

Crutchfield Customer Review (What's this?)

It sounds fine. For a few seconds. Then Bluetooth just drops, hissing and cracking. Tried with a variety of phones and laptops. They all work fine on other bluetooth connection (car, portable speaker) Only works through a cable.

Pros: Good sound.

Cons: Bluetooth does not work.

Very good, not perfect.

JeffS from Springfield MA on 7/5/2013

Crutchfield Customer Review (What's this?)

Quick and easy setup. Bluetooth pairing is fast and stays from one session to next. Speakers sound with Bluetooth connection is very good, but there is a noticeable improvement with connected via included 3.5 mm jack (as expected). Sound is more warm than bright and quite balanced. Bass response is moderate, and can be improved with placement on a shelf or in corners. The speakers sound is far superior to portables units and they can play quite loudly without obvious distortion. The only minor weak point is the Bluetooth connection. This is my second pair. The first sounded as described, but had frequent annoying dropouts (some prolonged). The new ones have this issue only occasionally and when it does occur, it is very brief and reconnects immediately. I notice no interference from other wireless devices nor any background hiss. Compared to my Jambox, the connection seems to be similar.

Pros: Excellent sound particularly when wired. Bluetooth sound with advanced Codec is significantly improved.

Cons: Bluetooth connection good, but not perfect.

Nuforce S3-BT Bluetooth Speakers

dee from PacNW on 1/17/2013

Crutchfield Customer Review (What's this?)

I am using these on my desktop pc system which includes a mac pro tower, external DAC (Modi). sound is clear, powerful, and produces a reasonable low-end given a 3.5" woofer. I have not tried in bluetooth mode yet with IOS device. But will do so when I travel with them. good value for the money! Now my PC desktop reference system, plus mobile solution as well. I have them in white which looks nice.




Hands-on research

Product Research


Overview: The NuForce S3-BT is an active loudspeaker featuring Bluetooth wireless connectivity with aptX for high-fidelity sound reproduction. It also includes stereo analog inputs for your non-Bluetooth devices and a USB charging port for your smartphone or tablet. The S3-BT's compact bookshelf size fits almost any room or decor. The speaker cabinet is wrapped in an elegant soft black or white leatherette (with black cloth grilles).

Two-Way Speaker Design: Each NuForce S3-BT Bluetooth speaker features a custom 1" soft-dome silk tweeter that offers a smooth and natural response, and a 3.5" composite paper cone woofer with rubber surround which is constructed using a proprietary "anti-resonance" cone technique and powerful magnet assembly. The drivers are housed in a bass-reflex enclosure with a rear-firing port.

Digital Amplifier: The NuForce S3-BT's right speaker employs an efficient Class-D amplifier (18 watt x 2 channel) which powers all drivers in the left & right speaker for clear, detailed sound and low power consumption.

Bluetooth Version 4.0: The NuForce S3-BT is Bluetooth v4.0 certified and supports wireless audio playback (AD2P) and control (AVRCP) of Bluetooth-enabled audio devices; such as your Apple iPod/iPhone/iPad, Android smartphone/tablet, computer/laptop, and digital audio/MP3 player. Basic playback functions include - Play/Pause and Previous/Next Track.

Bluetooth aptX Codec: Bluetooth aptX, which is featured on a growing number of Android mobile devices as well as MacBooks and Apple desktop computers, allows audio to be broadcast wirelessly in significantly higher quality than over standard Bluetooth. You'll instantly notice more extensive dynamic range, deeper bass, and crystal-clear top end. Standard Bluetooth has an extremely variable performance and its weaknesses are very apparent to music lovers. Common complaints include a reduction in high-end clarity, muddiness or dullness in the midrange, and its reduced signal-to-noise ratio can cause listener fatigue. Conversely, Bluetooth aptX has a fixed performance standard to guarantee a consistently high-quality wireless music transfer. With almost CD-quality reproduction to offer, you'll instantly experience significantly greater dynamics and infinitely more detail from your favorite music.

Compatible Music Sources: The range of music available from today's iPods, smartphones, laptops, and computers is almost endless. In addition to music stored on your iPod, smartphone, tablet or computer; online music services like Pandora, iHeart Radio, Spotify, Rhapsody, SiriusXM, and of course other internet radio sources can be wirelessly transmitted to the NuForce S3-BT.

SPP (Secure Simple Pairing): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled device to the NuForce S3-BT without having to enter pin codes or go through complicated settings. When a registered Bluetooth device is in close proximity to the powered speaker, the auto connection function automatically pairs the two units. Multiple Bluetooth-compatible devices can be registered, but only one device can be used at a time. Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the NuForce S3-BT.

Analog Inputs: The S3-BT's right speaker is fitted with stereo RCA inputs for connecting an external audio device, which is not Bluetooth-enabled. The stereo analog inputs can also be used for upgrading to the NuForce Air DAC wireless system (773AIRDAC, sold separately) offering even more outstanding audiophile grade audio performance.

Binding Posts: The amplified right speaker is equipped with binding-post speaker output terminals, while the passive left speaker is equipped with binding-post speaker input terminals. A 10' length of speaker wire is included to connect the two speakers.

Top-Panel Controls: The amplified right speaker features top-panel controls. Control include - Source (Bluetooth/Line-in), Play/Pause, Previous/Next Track, Volume Up/Down. The main power switch is located on the rear-panel of the amplified right speaker.

USB Charging Port: The amplified right speaker's USB type-A charging port (5V/1A) lets you charge your mobile device via a USB cable.
