Q Acoustics 3050i loudspeakers (pair)


 The Q Acoustics 3050i are an evolution of the original 3050 speakers which feature a number of improvements that substantially improve audio performance and aesthetics. 

They are striking speakers with twin 165mm (6.5 in) and 22mm (0.9 in) precision drivers that can be floor-mounted using rubber feet or spikes (provided). They also featuring rear outrigger plinths for extra stability.

The internal structure of the Q 3050i has been designed to incorporate what we have learned about minimising organ piping using Helmholtz Pressure Equalisation (HPE™). This greatly improves the linearity of the bass performance and the cabinet uses Point-to-Point (P2P™) bracing techniques to reduce intrusive cabinet vibrations both coming from our experience with Concept Series.

Foam bungs are provided for the rear-facing ports to help with less than ideal room positioning. The level of bass can be reduced to compensate, but definition and bass extension are increased.


At the heart of the 3050i is a wealth of technology to ensure they are a true step up from their predecessor. P2P™ bracing has been introduced to help keep the enclosure extra quiet, HPE™ to eliminate sympathetic resonance, equalising air pressure within the cabinet and a 22mm High Frequency Driver with a micro-fibre soft dome with wide surround which helps to create a wide, even dispersion of stereo. Just a few of the many technologies employed to elevate the 3020i.

Q Acoustics P2P™ (Point to Point) bracing supports the parts of the enclosure that need to be stiffened making the new enclosures exceptionally rigid, improving the focus of the stereo image and giving the soundstage more accuracy than ever before.

The 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.

The mid/bass driver 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.

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 floorstanding speakers to reduce cabinet resonance. This technology is perfect for taller loudspeakers that tend to resonate at a single favoured frequency.

Conventional terminal panel cut-outs have been removed, giving greatly improved structural integrity to the enclosures and new low profile binding posts have been incorporated with sockets deep enough to accept 4mm ( 0.16 in) banana plugs.
