The manufacturer Q Acoustics, founded in 2006 and based north of London in Hertfordshire, is expanding its concept product line to include a bookshelf speaker, a floorstanding speaker and a center speaker. Last but not least, a complete 5.1 home theater setup can now be put together with this series.
Q Acoustics Concept 30, 50, 90: technology, similarities and differences
All three new loudspeakers come with a three millimeter thick aluminum baffle and chassis, which are attached to this by means of pretensioned bolts – this mechanical trick is invisible from the outside. This is intended to dampen disruptive vibrations and prevent unwanted coupling with the main housing. Last but not least, the woofers and tweeters have been newly developed. The latter is hermetically sealed and mechanically decoupled from the baffle via a floating attachment. The crossovers were mounted at the maximum distance from the chassis on a special base in order to keep microphonic effects and magnetic interference as low as possible.
Of the Q Acoustics Concept 30 is a classic, compact two-way speaker with a 125 mm woofer and a 25 mm tweeter coupled at 2.4 kHz. The efficiency of the compact boxes, each weighing 8 kilograms, is declared as 87 dB / W / m.
The 23 kilogram floorstanding loudspeaker Q Acoustics Concept 50 Compared to the Concept 30, it is equipped with an additional 125 mm bass-midrange driver and plays down to 42 Hertz (-6 dB). At 90.5 dB / W / m, the free-standing model is even more efficient. The center Q Acoustics Concept 90 has the same driver equipment as the Concept 50 – and a comparable efficiency (90 dB / W / m)
All three models are available in white, silver and black, and suitable feet and wall brackets are also available for the Concept 30.
