If you love Sonos but want to keep and integrate your own high quality speakers, then the Sonos Amp is for you.

With a mighty 125 watts per channel, it’s ideal for all speakers, including floorstanders and installation speakers.

A wide range of inputs also make the Amp ideal for connecting a TV, games console, turntable (with phono pre-amp) or other music device.

It's time to experience the perfect harmony between your speakers and Sonos.

The Sonos Amp brings out the best of both, with an impressive 125 watts of power and an array of inputs.


  • POWERFUL AMPLIFIER: Offering 125 watts of power per channel, the Amp offers over double the power output of the Sonos Connect Amp. This extra wattage is beneficial when using inefficient speakers or when aiming to fill larger spaces with sound. Additionally, a subwoofer can be connected to the sub output for added low-frequency sound.

  • TOP QUALITY SOUND: The powerful Sonos Amp offers exceptional sound quality, thanks to its Direct-digital feedback amplifier with discrete output stage. The Amp boasts meticulously crafted black, painted circuit boards that increase cooling performance and reduce distortion.

  • SMALL BUT MIGHTY SPEAKERS: The Monitor Audio Climate 50 outdoor speakers are the most economical and compact options in the Monitor Audio Climate series. Featuring a 140 mm bass driver, these speakers are ideal for smaller patios or balconies and can be wall mounted in a variety of combinations for optimal sound dispersion over larger areas.

  • HASSLE-FREE SETUP AND INSTALLATION: The Monitor Audio Climate 50s come pre-equipped with wall mounts, making setup simple and straightforward. Both the speakers and brackets are designed for outdoor use, withstanding all types of weather for all-year enjoyment. Installation requires only 16 Gauge 2-Core Speaker Cable to be run from the Amp to each speaker. 

  • HOW IT WORKS: When connected to the Sonos Amp, the Monitor Audio Climate 50s form part of your multi-room speaker system and can be used in tandem with any other Sonos speakers in your home. With the ability to group rooms to playback the same music throughout your home or stream different content in each zone, the Sonos Amp can even be wirelessly linked with a Sonos soundbar and the in-ceiling speakers used as surround sound rears.
