QR SUB SE

A TRULY POWERFUL EXPERIENCE

The design goal of the QR SE series has always been to offer the most advanced technology in a perfectly finished and proportioned high-end package. The sound is big, bold, and dynamic, yet subtle and detailed when required—an excellent solution for all types of music.

The fascia plate of our Gold Leaf Air Motion Tweeter is machined from a single piece of Aerospace Grade Aluminium. It has been precision machined, glass blasted, brushed and then anodized in an attractive Tungsten Titanium Grey. It features a rose gold-plated dispersion mesh, which works as an S-Stop filter.

The new SE models all feature subtle, elegant, yet highly recognizable golden brass badges on the front panels and cloth grilles.

Our new highly specialized double cryogenic polypropylene tin flash copper capacitors are the result of constant listening, measuring, and improvement. They provide our AMT tweeters with the best possible conditions for sounding even sweeter, more detailed, and more open. The use of cryogenically treated pure copper wiring and Audiovector Nanopore damping material creates a smooth and natural musical reproduction.

The Audiovector Pure piston dual magnet bass drive units have the ability to work like a perfect piston over several octaves of the frequency band without the distortion normally found in aluminium/diamond drive units. This means music sounds warm, precise, and detailed, yet dynamic and musical.

Precision in Power and Flexibility. Featuring an exceptionally Controlled 10” Bass Driver and Downward-Firing Passive Driver for the Deepest Frequencies. Connect Directly to Your Amplifier

The QR Sub sports an exceptionally controlled and powerful 10” bass driver in combination with a downward-firing passive driver for the very lowest frequencies. Via its powerful internal amplifier, it is extremely flexible and can be connected directly to your loudspeakers or amplifier.

High level Speakon cable included 1 x 5 m.

With the addition of the powerful QR C SE, the detailed QR 1/3/7 SE, and the easily placed QR Wall SE, we are proud to deliver a very strong and powerful home cinema speaker solution.

MEET THE NEXT GENERATION OF ADVANCED SOUND
The QR SPECIAL EDITION is the result of continuous innovation that aims to bring listeners closer to the soul of the original music…and to make listeners really feel the music.

You’ll notice the improvements from the very first note:

➝ New in-house designed capacitors result in a cleaner treble and improved detailing.

➝ Improved heat dissipation via metal housed resistors delivers even more stable high-power precision.

➝ Cryogenically treated internal wiring improves dynamics and detailing.

➝ Strategically positioned Nano Pore dampening material enhances midrange openness.

➝ Bass reflex optimization increases precision.

➝ Stainless steel high-end spikes with knurled nuts allows easier micro adjustment.

AUDIOVECTOR QR DRIVE UNITS Leaving convention behind

Rather than buying off-the-shelf drive units, even from the most respected manufacturers, we prefer to develop our own. This allows us to co-engineer drive units in sync with our crossover designs.

Low-hysteresis coil technology. Large powerful magnets. Rigid turbulence-suppressing baskets and sandwich membranes, crafted from two layers of aluminum bonded together with a light foamy glue. We combine all three to achieve a far richer, clearer, and more vibrant sound compared to conventional technology.

QR AIR MOTION TRANSFORMER TREBLE DRIVERS The fastest available

AMT drivers are the fastest treble drivers available. Based on the revolutionary technology invented by Dr. Oscar Heil in the 1960s, they have zero mass to accelerate or decelerate, reaching over 40.000 Hz with optimal dispersion in both the horizontal and vertical planes. The upper limit, meanwhile, is as high as 102 kHz.

The tweeters’ lightweight precision mylar-membrane resemble the bellows of a harmonica – only smaller, lighter, and way faster. The gold-plated grid in front of the membrane reduces unwanted sibilants while improving dispersion and integration with the midrange driver.

ENCLOSURES WITH ROUNDED CORNERS High strength, low resonance

Our enclosures are produced from high density hardwood HDF, generously braced for high internal loss to deliver the perfect combination of high strength and low resonance.

BASS REFLEX PORT Deep and detailed

The internal damping of our Q-port is higher than on conventional ports to offer a more precise, deep, and detailed bass performance.

BASS REFLEX OPTIMIZATION Punch with precision

We have carefully realigned the bass reflex systems to deliver more punch without losing precision.

3D SOUNDSTAGE Be there

Our goal has always been a superb 3D soundstage that precisely positions the musicians. The AMT, Pure Piston drivers, and precisely specified crossovers all help to make this a reality.

MINIMUM DISTORTION Ultimate precision

The concept of Dynamic Feed Forward reduces the losses in our crossover by up to 50%. And our proprietary Audiovector doublecryogenically treated capacitors and high precision components (<0.8% tolerance), combined with in-house drive units, allow us to use a minimum number of components to achieve a high precision linear phase roll-off profile on all drivers. This improves dynamics, decreases loss, and reduces heat build-up.

IN-HOUSE DESIGNED CAPACITORS A sweeter tweeter

Our new highly specialized double cryogenic polypropylene tin flash copper capacitors, are the result of constantly listening,

measuring, and improving. They provide our AMT tweeters with the best possible conditions for sounding even sweeter, more detailed, and more open.

DESIGN ENHANCEMENTS Discreet style

The new models all feature subtle, elegant, yet highly recognizable gold brass badges on the front panels and cloth grills.

THE AUDIOVECTOR MISSION

➝ To optimize the pleasure of ownership and the thrill of listening.

➝ To innovate high-level technologies in the service of music. We only introduce a new material or technology if it allows us to optimize sound quality and listening pleasure.

➝ To carefully handcraft every single product in Copenhagen, Denmark.

➝ To maintain a ´form follows function´ design philosophy of timeless, elegant design and a sublime sound.

➝ To actively promote environmental conservation by creating the highest quality products that endure over time.
