Big speakers, huge ability and excellent value in high-end terms Tested at £4950 / $6500 / AU$9200
Many people associate great value with a low price. We at What Hi-Fi? don’t do that. Want to know why? Exhibit 1: the Audiovector QR 7 speakers. These 114cm high floorstanders are by all reckonings an expensive product, yet after spending a great deal of time in their company we still can’t believe that they offer so much for the money.
They are the range-toppers in Audiovector’s starter QR series and offer a great solution for those with larger rooms. Our test room is a fairly generous 3 x 7 x 5m in size, and that’s the kind of space that you’ll need to hear these speakers at their best. Go much smaller and the QR 7’s considerable low-end reach and scale start to become oppressive.
We have no complaints about the Audiovector’s build quality. Those large cabinets are superbly made and are finished to a high standard. Their bulk could have been an issue but smart aesthetics help the QR 7 blend into a wide range of rooms. To our eyes, they look expensive, classy and uncluttered. There are three finish options: Black Piano, Dark Walnut and White Silk.
These floorstanders are a three-way design, marrying an AMT (Air Motion Transformer) tweeter to a 15cm midrange and a pair of 20cm bass drivers. AMTs use a pleated diaphragm that moves air with a concertina-type motion. Audiovector is no stranger to such designs, having used them extensively over the years. Here, the tweeter is fronted by a specially designed mesh grille that is claimed to reduce sibilance.
The midrange and bass units all use composite cones where two thin skins of aluminium sandwich a layer of damping material. The idea is to combine high levels of rigidity with low resonance, which should result in strong dynamics coupled with plenty of detail resolution.
The crossover points are pretty conventional with the bass driver handing over to the midrange at 425Hz and the mid to the AMT at 3kHz. These speakers are designed to be relatively undemanding to drive, and the numbers bear this out with a claimed sensitivity of just over 90dB/W/m and a 6 ohm nominal impedance. Take a look at the QR 7’s impedance curve and you will find that their load isn’t particularly demanding at any part of the frequency range, so they should work well with most amplifiers from an electrical compatibility point of view.
