Key Features
The Q Acoustics Concept 300s are premium bookshelf speakers featuring a two-way driver design that delivers clear and commanding stereo sound. This consists of a 165mm paper cone mid/bass driver with a 35mm voice coil and ferrite magnet, coupled with a 28mm microfibre tweeter placed closely above it. To isolate the drivers, the tweeter has been decoupled from the speaker cabinet using a specially designed rubber gasket. The result is an exceptional sonic performance with dramatically reduced resonance, ensuring punchy and dynamic sound quality suitable for a range of genres.
To ensure a superior level of acoustic performance, Q Acoustics have utilised the Dual Gelcore technology first seen in the Concept 500 Floorstanding Speakers. This design effectively dissipates high-frequency energy by converting it into heat. Augmented by the meticulously engineered Point-to-Point Bracing and the Isolation Base System, Q Acoustics have integrated these speakers with a high degree of dampening technology to achieve a listening experience unmarred by cabinet vibration. With both bi-wiring and bi-amping compatibility, the Concept 300 promises seamless hi-fi integration.
Nearly New: This product may have been opened for quality control purposes, returned by a customer, refurbished, or may have non-essential parts or software missing. Otherwise, the product operates as new. This is a great opportunity to buy a fully functioning product at a discounted price, supplied with a one-year warranty.

The superior audio delivery of the Concept 300 is augmented by high-quality drivers and a meticulously crafted crossover system, fostering wide dispersion for an immersive sonic experience. Complementing its exceptional performance is a visually stunning exterior—crafted with numerous lacquer coats and real-wood veneers—that exudes a luxurious gloss finish, elevating any space they grace. Q Acoustics' engineering team embarked on a mission to redefine speaker stands, aiming to reduce their acoustic footprint. Their innovation resonates profoundly as these stands, with their smaller surface areas, remarkably minimize sound transmission into the room. The result is tangible—a physical absence of vibrations during playback, unveiling the Concept 300's remarkable clarity and transparency, leaving listeners captivated by their quiet yet commanding presence.
Since its founding in 2006, Q Acoustics has built an unrivalled reputation for designing, engineering and manufacturing innovative, high-performance and class-leading loudspeakers at every price-point. This ongoing and concerted demonstration of excellence has all led to Concept 300. The brief for Concept 300 is simple, yet staggeringly ambitious. Build on the runaway success of the floorstanding Concept 500 and deliver a standmounting alternative that’s at once more affordable, of utterly uncompromised performance and of stylish, understated elegance.
The mid/bass driver is a 165mm impregnated/coated paper cone with very low resonance thanks to its high-performance rubber surround. It sits in front of a large (35mm) glass fibre voice coil and equally substantial ferrite magnet. The result is midrange and bass response that’s as punchy and dynamic as it is poised and eloquent. Above it, the 28mm high-frequency driver, made of super-fine strands of coated microfibre, is decoupled from the speaker cabinet using a rubber gasket. This protects the tweeter from sending or receiving unwanted vibrations and allows it to be mounted close to the mid-bass driver. This improves integration with the larger driver and the very subtle horn-shaped profile to the tweeter’s front plate allows perfect impedance-matching with its environment without colouring performance.
The intelligence of the design of the Concept 300 cabinet is evident in its use of P2P (point to point) bracing. Q Acoustics is able to measure the performance of the cabinet structure at a microscopic level, and identifies the precise positions that require support. So the P2P targeted cabinet-bracing method means the cabinet has exactly the support it needs, and no more. In this instance, a long and involved analysis of a problem results in a simple and brilliantly effective solution.
Ideally, the only vibrations a loudspeaker produces are the ones required to generate its sound. Of course, it’s not possible to entirely rid a loudspeaker cabinet of unwanted vibrations that can interfere with its performance but, as Q Acoustics has demonstrated with Concept 300, it is possible to keep cabinet vibrations to an absolute minimum in order to deliver entirely uncorrupted sound. Q Acoustics uses MDF rather than one of the more glamorous and/or expensive alternatives to construct the Concept 300 cabinet. There are a couple of reasons for this: alternative materials offer no benefits in terms of damping, or even ease and simplicity of construction, over the very high performance MDF delivers, and more expensive materials simply drive up the eventual price of the speaker for no audio gain whatsoever.
Having dealt with lower-frequency vibrations using P2P bracing, Q Acoustics then negates higher-frequency cabinet vibrations using its bespoke Dual Gelcore technology. The Concept 300 cabinet is comprised of three individual layers, each separated by a non-setting gel - the gel acts rather like a high-tech and extremely effective gasket. Any stray high-frequency vibrations are converted into heat which dissipates within the gel.
On the outside, numerous lacquer coats produce a high-quality gloss finish which is combined with real-wood veneers. This results in a cabinet that manages to be clean and understated at the same time as being of obviously high perceived value. The uncluttered look of the cabinets is further enhanced by innovative drive unit mounting. Both the tweeter and mid/bass driver are fixed, from behind, by strong spring-tensioned retaining bolts which negate the need for any exposed bolt-heads on the speaker face. At the rear of the speaker, Concept 300 features an over-specified terminal panel which is designed to resist vibrations from the cabinet. It’s equipped for bi-wiring (or bi-amping) via its electrically isolated terminals - these can accept bare wire, spade connectors or 4mm banana plugs.
A combination of rigorous engineering, uncompromised industrial design and aspirational aesthetics makes Concept 300 the most fully realised loudspeaker Q Acoustics has yet delivered. In combination with the equally meticulous Tensegrity stand, Concept 300 represents a step-change in loudspeaker design and a redefinition of what is possible at its price.
With a standmounting speaker design like this, of course, the speaker’s relationship with its stand is of fundamental importance. And it’s the design of the new Tensegrity stand, and the new isolation base suspension system that joins Concept 300 to it, that allows Q Acoustics to redefine the level of performance that’s possible from a smaller loudspeaker.
Tensegrity is a tripod - by definition, an extremely stable structure. It’s built from lightweight aluminium tubes (which are the load-bearing element) and thin stainless steel cables (which maintain the position of the load-bearing tubes). The result is a light, exceptionally rigid and self-supporting structure with a remarkably low surface area and - let’s not pretend otherwise - beautifully elegant appearance. It’s not so much a speaker stand, it’s more an entirely new loudspeaker support concept.
But, of course, it’s of little consequence how efficient your speaker cabinet is, or how ingenious the design of the stand it works from, if the union between the two is unsympathetic or inefficient. Q Acoustics joins Concept 300 speaker to Tensegrity stand with the new isolation base suspension system, which is about as sympathetic and efficient as it gets.
The entire mass of Concept 300 is suspended on the four springs of the newly developed integrated base plate. This isolation base system works in multiple ways: it prevents energy from the speaker leaking into the Tensegrity stand and affecting the sound, it prevents vibrations for the floor making their way from the stands into the speaker, and in every circumstance it provides a rigid coupling between speaker and stand.
Thanks to the combination of Tensegrity stand and isolation base suspension, the performance of Concept 300 is entirely unhindered by internal or external influences.
