Audiovector QR Sub SE

Audiovector QR Sub SE - A refined and powerful subwoofer

The new QR Sub SE is part of Audiovector’s entry-level series, but you would never guess that just by hearing it. The bass from this subwoofer is exceptionally cohesive, well-controlled, and powerful thanks to its highly sophisticated and innovative design. This design includes, among other things, a 10" woofer combined with a passive downward-firing unit that handles the very lowest frequencies, and an extremely high-current amplifier. The built-in amplifier provides incredible flexibility, allowing you to connect it directly to your amplifier or directly to your speakers through the "Speakon" connection.

Highlights

The SE series offers notable improvements

Compared to its predecessor, the new SE model delivers even more open, dynamic, and detailed sound reproduction. It is a very clear and audible improvement that is easy to hear in an A/B demonstration.

The improvements in the SE series include, among other things, a new crossover with better performance in the bass response frequency range. All internal wiring is now cryogenically treated, having been frozen down to -236 degrees to reduce resistance and improve signal transmission.

Audiovector has also improved the damping inside the cabinets using NanoPore™, which until now had only been used in the most exclusive and much more expensive Audiovector models. The SE series has received an optimized damping factor, improving dynamic and aperiodic performance. They have also been fitted with new precision-milled spikes with a knurled locking nut for easy adjustment.

The subwoofer for the QR series

Like the rest of the QR series, the QR Sub SE features the well-known Pure piston unit, which in short is a 3-layer sandwich cone where the two thin layers of aluminum act as the "bread" and the inner foam core as the filling. Audiovector has done this to take advantage of aluminum’s light and rigid properties, while the internal damping material ensures that the cone does not create unwanted resonances or break up the sound at higher frequencies. This cone technology allows the subwoofer to deliver honest, sophisticated, and fast bass reproduction that never turns into mere boomy bass. It gives instruments like drums extra punch and depth, making it a perfect match for the speakers in the rest of the QR series. However, that does not mean it is only suitable for use with Audiovector speakers - the vast majority of speakers will benefit from the QR sub’s extra depth, which adds greater dimensionality to any kind of music.

Minimalist design with a beautiful finish

The QR sub is available in the same colors found throughout the rest of the QR series. This means you can get the QR sub in a discreet satin white, allowing the subwoofer to blend beautifully into bright surroundings without drawing too much attention to itself. The slightly more eye-catching finishes are a beautiful high-gloss black piano lacquer and a dark walnut veneer, where the wood veneer is of course real, in keeping with Audiovector’s DNA of high quality.
