Dali Oberon 7C + SoundHub + NPM-2i BluOS
Dali Oberon 7C active floorstanding speakers paired with the SoundHub and NPM-2i BluOS card, for hi-fi listening without a separate amplifier, via WiFi streaming.
Description
The Dali Oberon 7C are 2-way active floorstanding speakers in a bass-reflex configuration, designed to operate without an external amplifier thanks to their pairing with the Sound Hub and NPM-2i BluOS card. This set integrates a WiFi streaming source, a DAC and a hi-fi preamplifier directly connected to the speakers, simplifying the setup of a stereo or home cinema system.
Each floorstanding speaker houses two 17 cm bass-midrange drivers in wood fibre with SMC technology, paired with a 2.9 cm soft dome tweeter, all driven by a dual digital amplifier of 50 W RMS per channel. The frequency response extends from 31 Hz to 26 kHz, with a maximum sound level of 108 dB at 1 W/1 m, a crossover frequency of 2.450 kHz and a bass-reflex tuning of 40 Hz, figures that reflect a reproduction capable of covering large rooms without losing precision at low volume. The Sound Hub handles wireless I2S digital transmission to the speakers, 24-bit/96 kHz WiFi streaming in 2.4 GHz and 5 GHz, AirPlay 2 compatibility and the BluOS app, as well as pre-out outputs and an Ethernet connection for wired installations. The set is Hi-Res Audio certified and 24/192 compatible.
This configuration is aimed at those seeking a high-fidelity stereo or home cinema setup without multiplying separate electronic components, in rooms large enough to let the music breathe at high volume. It will suit both audiophiles who appreciate nuanced listening and those looking for simplified integration with control via smartphone or tablet.

What to check before buying used
On this type of active system, checks focus mainly on the Sound Hub and the NPM-2i card, the electronic components that drive the amplification and streaming: their proper functioning determines the full use of the speakers. Testing the WiFi connection on 2.4 GHz and 5 GHz, as well as AirPlay 2 and BluOS compatibility, ensures the streaming module responds correctly. The condition of the bass-midrange drivers and tweeter should also be checked, along with the cast alloy plinth that holds the coupling spikes or speaker feet.
