Last month Q Acoustics released the new concept 40 at the Bristol show, answering important speaker related questions. The concept 40 is A floorstanding speaker priced at £1000 a pair. It is similar to the concept 20, however this time it is larger and has some unique features such as ‘gelcoreTM construction’ which has many known benefits as explained by Alex Munro, the Q Acoustics’ Brand Director who represented Q Acoustics at the Bristol show.
Gelcore Construction’TM means the Concept 40 benefits from what can best be described as a ‘cabinet within a cabinet’, with a special resonance-cancelling compound adhering between the inner and outer shells. This cabinet is both rigid and exhibits extremely low resonance. The latter is achieved because the resonance-cancelling compound absorbs the kinetic energy (movement) generated within the inner cabinet by the drive units, and disperses this energy by converting it into heat.
When compared to a good conventional cabinet, radiated power (colouration) throughout the critical mid-band (voice frequencies) reduces by an average of more than -6dB. In the high and low frequencies the effect is even greater, with improvements in excess of -10dB.
Since the concept 40 is larger, this also means that it is heavier, 5.5 kg more than the concept 20. It can take up to double the wattage at 150 W of the previous model and has a lower frequency response from 64 to 53 Hz. As it is on floor stands this means that it will help get the floor shaking with the extra bass. You shouldn’t get too hooked on sensitivity, but the Q Acoustics concept 40 has a maximum of 90 dB, again for decibels more than the concept 20. You get what you pay for, the concept 20 with stands are half the price of the concept 40 but are honestly not quite as good.
As quoted from Alex Munro
Make no mistake, the new Concept 40 is special. It delivers a sonic performance which until now, has only been enjoyed by those privileged enthusiasts who could afford wonderful, but very expensive, ‘high end’ loudspeakers.
Of course with such high-end speakers you would expect a five year warranty, and that is exactly what you get. Q Acoustics have achieved yet again what sounds like an excellent speaker.
