Use it by itself for music in a smaller room. Pair two Formation Flex speakers for stereo sound. Or use a pair with a Formation Bar and a Formation Bass for a wireless 5.1 home theater system.

Ready for multi-room audio

Formation speakers create their own patented, robust mesh network. This ensures proper bandwidth for high-res audio streaming, without overtaxing your home Wi-Fi® network, as well as near-perfect speaker synchronization.

High-performance speaker design

The Formation Flex features a version of the company's highly acclaimed decoupled double dome tweeter and a bass/midrange driver with a woven glass fiber cone. The speaker also has 24-bit/96kHz streaming audio resolution. This ensures clear, accurate sound and that the Flex will do justice to your high-resolution music files.

Simple multi-room app control

Formation wireless speakers are easy to use, thanks to the Bowers & Wilkins Home app. Download it from the Apple App Store or Google Play to your smartphone or tablet. The app walks you through the setup process. It also lets you add other Formation speakers easily as you build out your multi-room audio system.

You can assign room names to your Formation speakers, group them to simultaneously play the same song, or play different songs from different sources in each room.

Wireless options

The Formation Flex features Bluetooth 4.1 for playing audio sources from a wide variety of apps on your mobile device. Built-in aptX HD and AAC decoding provide high-quality music streaming from compatible devices.

Spotify Connect is built-in, too, so you can easily stream from this popular service if you have a subscription.

Built-in Apple AirPlay 2 technology lets you play audio directly from your iPhone®, iPad®, or Mac® computer through the Formation Flex. That includes soundtracks from YouTube® videos and Netflix movies.

Roon-compatible for serious music lovers

The Formation system is also compatible with Roon, a subscription digital music player for your smartphone, tablet, or computer. It gives you multi-room audio playback for all your Formation devices and more.

Roon accesses your digital music collection from your iTunes library or NAS drive. It also works with your TIDAL subscription. Roon lets you do deep dives into your music, showing artist bios, photos, reviews, and lyrics. Roon can also suggest other artists and songs based on your selections, making it easy to discover new music you'll enjoy.

To use Roon you will need a Roon Server running on the same network as the Formation Audio and other Formation Series products. The  is media software that runs on your computer, NAS, or Roon component (like Nucleus or Nucleaus Plus - sold separately), located on the network within your home.

  • Supported Codecs: In addition to support for Bluetooth's standard SBC audio codec, the Formation Flex supports AAC for higher quality playback from Apple iOS devices, as well as support of aptX HD for 24-bit/48kHz audio playback from compatible devices. aptX HD supports 48kHz/24-bit LPCM audio over a Bluetooth wireless connection for a "better-than-CD" listening experience.
  • Multi-Device Pairing: Up to eight Bluetooth devices can be paired with the speaker, but only one can be connected and used at a time. The Formation Flex does not support auto reconnection with previously paired Bluetooth devices.

Note: The Formation Flex will require a network connection and the Bowers & Wilkins Home app to complete to complete the pairing process of your Bluetooth-enabled source devices.

Applications & Mounting Options: The Formation Flex can be used as a single mono speaker, as a compact stereo pair, or as rear surround speakers in a home theater setup. The Formation Flex can be paired with another Formation Flex speaker (sold separately) to create a wireless stereo pair. Two Formation Flex speakers can also be paired together to create wireless rear speakers for B&W's Formation Bar soundbar speaker (749FORMBAR, sold separately). The Formation Flex speaker can be placed on a shelf, table, or stand (sold separately - see Accessories Tab). It does not offer a bracket, threaded-insert, or key-hole slot to wall-mount the speaker.

  • Stereo Pairing: When used as a stereo pair with another Formation Flex, the speakers should be at least 3' apart and a similar distance from the listening area. If the speakers are positioned too close together, the stereo reproduction may lack scale. If they are too far apart, the stereo focus may be weak. There is no need to angle your Formation Flex inwards towards the listening area however doing so may tighten the stereo focus.
  • Wireless Rears: When paired with another Formation Flex speaker and used as rear speakers with the Bowers & Wilkins Formation Bar, the wireless rear speakers should be placed as close to 120-degrees from the soundbar speaker as possible.

Note: The Formation suite of products are not moisture resistant, as they are not designed to be used in high-humidity or moisture rich environments. Positioning a Formation product in a moisture rich environment such as a bathroom or sauna, could cause damage to the product that would not be covered under its manufacturing warranty.

Optional Wireless Powered Sub: Add the Bowers & Wilkins Formation Bass wireless powered subwoofer (749FRMBASS, sold separately) to a single Formation Flex speaker or a pair of Formation Flex speakers for deeper bass from your music soundtracks.

AC Power with Auto On/Off: The Formation Flex comes with a detachable 6.5' AC power cord that plugs into the bottom of the wireless speaker and into an AC wall outlet or surge protector (sold separately - see Accessories Tab). The Formation Flex will automatically turn on when it senses a wireless audio source signal. The wireless speaker will automatically power off after twenty minutes of no audio signal and no operation.

Note: The Formation Flex wireless audio speaker is not battery powered.

They are not a battery operated speaker. They sound great either alone or as a pair, but they are not picic or by the pool bluetooth battery operated. Perhps a JBL might be a better choice for you if portability is your primary need. Good luck.
