Q-Acoustics Active 200 is a Hi-Fi class wireless bookshelf speaker. Amplifier modules operating in Class D are used, and band-pass amplification with active crossover based on DSP is implemented. The Q Active 200 shelf model has six amplifiers with a total power of 280 watts.
This is not the tiniest model: each column weighs about 15 kg, which is quite a lot for shelves. On the front panel there is a 6.5-inch midbass speaker and an enlarged 1.1-inch tweeter. At low frequencies, the bass is assisted by a bass reflex mounted on the back panel.
The Concept 30 used specially designed radiators: 5-inch midrange/woofer speakers with enlarged 30.5 mm coils and 0.9-inch tweeters mounted on 3 mm thick aluminum plates. The tweeter is placed in a sealed volume and is completely isolated from the body by means of a "floating" suspension. The midrange/woofer sound coil is 30.5 mm in diameter.
The Q Acoustics Q5010 is a bookshelf speaker that stands between the 3000i models and the older Concept series. Many technologies of Q Acoustics 5000 cabinets and drivers are borrowed from the latter. In particular, this is the design of the C3 Continuous Curved Cone woofers/midrange speakers, about which Q Acoustics stated that the C3 "will form a technological platform for many years to come."
The M20 stereo pair is made according to the classic master-slave principle, when all the electronics are concentrated in one of the speakers. This is an amplifier that outputs 65 watts per channel, and a DSP module with the ability to adjust the sound depending on the location of the speakers: in a corner, against a wall, or freely. A 22mm tweeter and a 125mm woofer are responsible for the sound in each speaker. The audio signal of the Q Acoustics M20 is received via Bluetooth 5.0.
