Q Acoustics Active 400 is a powerful high–resolution wireless stereo system with support for Bluetooth, AirPlay 2, Chromecast, Roon, Amazon Music, Apple Music, Deezer, Qobuz, Spotify, Tidal, HDMI ARC, providing uncompromising Hi-Fi sound. The system consists of two active outdoor speakers and a wireless hub with additional connectors.
The Concept 50, a derivative of the flagship Concept 500, uses HP technology. Thanks to HP (Helmholtz Pressure Equalizer) technology, distortion is minimized. Large speaker housings can create pressure in certain areas, causing resonance and distortion of the housing.
The Q Acoustics 5040 tweeter is equipped with a silk dome that is connected to a concave suspension, which improves off-axis directional characteristics. The tweeter is located between two accounts/woofers, i.e. in the D'apolito configuration, which also contributes to optimal off-axis characteristics of the reproduced sound.
The active floorstanding loudspeakers are equipped with Class D amplifiers with a power of 100 watts per channel. The built-in Bluetooth 5.0 module uses the aptX HD and aptX Low Latency codecs, in addition, there are analog RCA and 3.5mm inputs, as well as a digital optical input. The streaming module and network interface, as well as the HDMI input are not provided.
The Q Acoustics 3050c has a strikingly curved body that uses Q Acoustics' patented P2P mounting technology. There are also Helmholtz pressure equalization tubes. There are no visible connections or fasteners, and internal spacers connect the parts of the body that are most susceptible to resonances.
