Audiovector QR5 floorstanding loudspeakers

Audiovector is a company that gets a lot of coverage but still doesn’t get the recognition it deserves! I guess some of that is because there are still a lot of Danish speaker makers and some inevitably have more marketing power than others, but Audiovector remains on top of a lot of contemporary trends. A few years ago it introduced its Active Discreet range of loudspeakers with wireless connectivity and amplification provided by a ‘discreet’ black box that can be connected to a range of models. It was also one of the first dedicated two channel brands to introduce in/on-wall loudspeakers and OEM versions of these were included in Naim’s NaimNet multi-room systems back when that wing of the company was in business.

The QR series is the entry level range for Audiovector yet the speakers are built in Denmark at the company’s Nordhavn facility. The cabinets are sourced externally as is the case with almost all remotely affordable models today. The range consists of a stand-mount, centre channel, sub, and on-wall models alongside two floorstanders of which the QR5 is the largest and latest. The QR range feature a planar ribbon tweeter instead of the more common dome design – specifically an Air Motion Transformer model that has been dubbed Gold Leaf. There is a mesh in front of the driver that’s plated in rose gold and which is designed to work as an S-stop: a filter that controls sibilants. It is intended to work in the same way as the pop filters placed in front of microphones for singers in a studio. The tweeter sits in a machined aluminium faceplate that’s anodised in a tungsten titanium finish to contrast with the gold. It’s a very slick loudspeaker all round with post formed top corners and attractively branded aluminium trims around the mid and bass drivers.

The latter are a new design for Audiovector with a sandwich cone construction that combines two layers of aluminium with a filling of damping material to minimise ringing, it’s an approach that we have seen used by a variety of manufacturers but this is one of the smaller brands to go to such lengths. The midrange and two bass drivers look identical; they are both six inch types with ‘Pure Piston’ cones but the differences are behind this slick façade. They have different voice coils, resonant frequencies, cone weight, frequency response, and sensitivity. Within the cabinet the midrange has its own sealed asymmetric enclosure to nullify standing waves. The mid takes care of frequencies above 300 Hz and hands over to the tweeter at 3kHz. The system as a whole has a higher than average sensitivity of 91dB, but that is for a four Ohm impedance; at the more commonly quoted eight Ohms that figure would be 3dB lower.
