The Bluesound PULSE 2i is the flagship all-in-one wireless multi-room streaming speaker in the Bluesound range, designed to fill large rooms with rich, detailed hi-res audio. Its bi-amplified driver arrangement delivers 150 watts of total system power through two 5.25" PSB woofers and two 1" PSB tweeters, with bass extension down to 33 Hz (-10 dB) - performance that comfortably outpaces most speakers of similar form factor. Running on the BluOS platform, the PULSE 2i connects to your home Wi-Fi straight out of the box and streams from 17+ music services including Spotify Connect, TIDAL Connect, and Qobuz, with Apple AirPlay 2 and two-way aptX HD Bluetooth 5.0 also built in. Its advanced DSP engine manages the stereo soundfield in real time, extending it well beyond the physical cabinet to create a genuinely room-filling presentation. Pair two PULSE 2is together for a dedicated left/right stereo configuration with an even wider, more dynamic soundstage. 150W Bi-Amplified Flagship Performance: Four PSB drivers - two 5.25" woofers at 65W each and two 1" tweeters at 10W each - deliver full-range sound from 40 Hz to 20 kHz with bass extension to 33 Hz, in a sealed enclosure engineered for clean, controlled low frequencies. Advanced DSP Soundfield Engine: Bluesound's sophisticated DSP processing extends the stereo image well beyond the physical cabinet, maximising clarity and dynamics at any listening position in the room. Hi-Res Audio Support: Streams FLAC, MQA, WAV, AIFF, ALAC, and more at up to 24-bit/192kHz, with a high-end DAC handling MQA decoding in full for master-quality playback. BluOS Multi-Room Integration: Group the PULSE 2i with any other Bluesound player for whole-home hi-res streaming across multiple zones, all managed from the BluOS app on iOS, Android, Windows, or macOS. Two-Way aptX HD Bluetooth 5.0: Stream music from any Bluetooth device in better than CD-quality, or transmit wirelessly outward to Bluetooth headphones and speakers - without needing the app. Flexible Wired Connectivity: A combo Toslink/3.5mm analogue input, USB Type-A port for local storage, and 3.5mm headphone output give you physical connection options alongside the wireless streaming capabilities.
