Leading Technology; Outstanding Performance 

The Q 3050i speakers boast a range of unique technologies including HPE™ and P2P™ to ensure these floorstanding speakers deliver a truly exceptional sound.

HPE™ (Helmholtz Pressure Equalizer) technology designed to convert pressure to velocity and reduce the overall pressure gradient within the speaker enclosure, has been applied to the Q 3050i to reduce cabinet resonance. This technology is perfect for taller loudspeakers that tend to resonate at a single favoured frequency. (** Q 3050i only)

Q Acoustics P2P™ (Point to Point) bracing across the entire 3000i Series supports the parts of the enclosure that need to be stiffened making the enclosures exceptionally rigid, improving the focus of the stereo image and giving the soundstage more accuracy than in previous ranges. (* entire series )

High Frequency Driver Unit For An Unaltered Sound

Q 3050i tweeters are decoupled from the baffle via a compliant suspension system. Vibrations from the woofer, which can impair the performance of the tweeter are isolated allowing the tweeter to perform with dramatically reduced interference.

Mid/Bass Driver

Whichever 3000i model you choose the cone is precision formed from impregnated and coated paper and teamed with a newly developed, low-hysteresis, rubber surround. The coated paper cone provides the optimum balance between stiffness and self- damping which means it can accelerate without flexing and stop very accurately without unwanted resonances.

Beautiful Inside & Out

Q 3050i features an all-new enclosure aesthetics and offers 4 new contemporary finishes; Graphite Grey, English Walnut, Carbon Black or Arctic White. All are finished with an attractive chrome bezel around each driver and feature magnetic speaker grilles.

Low profile binding posts have been incorporated into the Q 3050i with sockets deep enough to accept 4mm Banana Plugs. This floorstanding speaker can be positioned very close to a rear wall even when banana plugs rather than spades or bare wires are used.

XT40 celebrates QED's 40 years of award winning British heritage. Winner of 'Best speaker cable' at the 2014 What Hi-Fi? Awards. This Five Star award winning pure copper loudspeaker cable boasts QED's advanced X-TubeTM technology and a massive 4mm2 cross sectional area. This results in a cable that delivers clear sonic advantages over conventional cable designs by maintaining a flat frequency response within the audio band.


At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTM delivers greater detail and fidelity across the audio spectrum which would other wise be lost in ordinary cables.

LARGE cross-sectional area: The 4mm2 cross sectional area means XT40 exhibits very low resistance, allowing amplifiers to exert outstanding control over the speakers they are driving. In addition, its large cross sectional area makes it suitable for long cable runs.
