Key specs that matter

Every enclosure houses a 25 mm silk dome tweeter and a 13 cm mid-woofer. A Class D amplifier rated at 2 x 50 W RMS drives both speakers, and Triangle quotes a response of 56 Hz to 22 kHz within 3 dB. A single cabinet measures 165 x 304 x 235 mm and weighs 5 kg, while the pair in its carton weighs 11.5 kg. Wireless options include Bluetooth 5.0 with aptX HD, aptX LL, standard aptX, AAC and SBC, plus 2.4 GHz Wi-Fi to the 802.11 b/g/n standard. Wired inputs are an RCA pair, a 3.5 mm mini-jack, an optical socket and a USB-A port, complemented by a subwoofer output. Wi-Fi and optical sources run at up to 24-bit/192 kHz, while Bluetooth HD reaches 24-bit/44 kHz.

Engineering and use context

All electronics, the amplifier, the streaming module and the connections live in one master speaker, which feeds the second, passive cabinet over a single cable. The RCA pair doubles as a phono input through a built-in moving magnet preamplifier selected with a switch, letting a record deck plug straight into the master speaker. AirPlay and Spotify Connect are supported, and the network module handles Deezer, Tidal, Qobuz, Amazon Music and TuneIn radio, with playback of FLAC, WAV, ALAC, APE, MP3 and AAC files. Multiroom is based on Linkplay technology and links up to five devices over Wi-Fi or ten over RJ45 connections. An infrared remote is included. Triangle recommends the pair for listening rooms of up to 25 m2 and offers finishes including English Green, Abyss Blue, Linen Grey, White, Brown Maple, Black, Eggplant and Macassar.

Pairing

The optical input takes a television signal, and the sub out connects an active bass unit for content below the bass limit of the cabinets. With the amplifier and streamer on board, an outboard amp or network player is unnecessary, and both constant and variable bitrate compressed files are supported alongside lossless formats.

Alternatives

The Triangle Borea BR03 Connect is a larger powered bookshelf pair from the same maker, with 16 cm woofers, 2 x 60 W Class D amplification, an HDMI ARC input and a USB-B computer connection.
