Twenty Digital Audio Amplifier

Walk in the door. Hit play.

Twenty is a digital audio amplifier ­- 20 watts per channel ­- that streams the highest­-quality audio via Bluetooth from your phone right to your speakers. Thanks to a 30­-foot Bluetooth range, the days of being tethered to your stereo are over.

Effortless listening.

With Twenty’s single­-button design, it’s never been easier to come home and start listening to music. Just press the Quick Connect button on the front of Twenty to reconnect a previously paired device and start listening immediately.

Beautiful audio.

Using high­end AAC / aptX audio streaming codecs, Twenty delivers crisp and clean playback to your speakers. Whether you’re streaming from your phone, gaming or watching a movie, Twenty streams the best sounding Bluetooth and digital audio that you (and your speakers) have ever heard. At 20 watts per channel, Twenty provides ample volume for your home or office.

Simple to set up.

Twenty was designed with simplicity in mind. Connect your speaker wire (or banana plugs) to the speaker posts, pair your phone or tablet to Twenty, and hit play.

Twenty works great with your unpowered speakers. - but what if you need new speakers? We’ve got you covered!
