Dual Gelcore Cabinet
High frequency cabinet noise is dealt with by the use of Dual Gelcore™ technology. The speaker cabinet is constructed in three separate layers and the resulting interstices are completely filled under pressure with a compliant form of non-setting gel. The two constrained layers effectively damp the walls of the speaker cabinet by converting high frequency vibrations into heat, which is then dissipated. The Dual Gelcore™ technology significantly reduces the ability of the cabinet to interfere with the accurate reproduction of the source material.
High Frequency Driver
Finite Element Analysis was used to model the acoustic performance of the soft dome and surround for optimal axial dispersion. Too narrow a high frequency dispersion characteristic means the speaker will not drive the room well, making it sound flat and underwhelming unless the listener is sat in the exact 'sweet spot'. Mechanically de-coupled, the HF driver is isolated from the cabinet for the most accurate sound.
From the outset, in keeping with a policy of proprietary development, the 165mm mid/bass drive units were designed exclusively for the Concept 500 project. The unusually large 35mm voice coil is a copper clad 2+2 configuration, which increases power handling, and increase force for a given input without adding extra mass. An Aluminium inductance ring and a copper cap to the pole piece ensure low distortion.
The cast aluminium base supplied with the concept 500 is securely mounted to the bottom of the cabinet. A speaker that doesn't sit solidly on the floor will not be able to deliver its ultimate performance because the speaker cone energy will not be transferred into the air in a completely linear way. Because the plinth is designed without large flat areas and is simply chrome plated without adornments it does not encourage deleterious effects.
The Concept 500 is equipped for bi-wiring or bi-amping with electrically isolated and oversized HF and LF terminals which can accept bare wires, spades, or 4mm banana plugs. If connected using a single run of cable, the best performance will usually be obtained using bi-wire links made from the same cable ans the speaker cables. Q Acoustics recommend QED cable.
Attention To Detail
The rear access panel has been constructed to maintain the integrity of the Dual Gelcore™ cabinet. The rear access panel in particular has been constructed by sandwiching layers of MDF, steel, and bitumen to main the integrity of the Dual Gelcore™ cabinet.
Best Product 2017 - 2018 - Floorstanding Speaker
Mainstream speaker makers often struggle when they move upmarket, but not Q Acoustics. The Concept 500 is an audacious new floorstander employing highly optimised drivers and cabinet. This svelte new loudspeaker comes in a choice of white or black gloss, with contrasting real wood veneers. The special tweeter blends seamlessly with twin mid/bass drivers, which are set into the heavily braced, multilayered gel-lined cabinet. This loudspeaker sounds refined way beyond its price, with a neutral yet musical performance.
Hi-Fi News - Outstanding Product
The sum-up is pretty simple: the Concept 500s are nothing short of sensational value for money, and capable not only of revealing exactly what your system is doing, but also embarrassing some pricier rivals. Beautifully finished and with a rich, yet tightly defined sound, they respond well to care with positioning and being driven by highly accomplished electronics.
AV Forums - Reference Status
"It might be a whole new price point for them but Q Acoustics has built another speaker that is the new standard to beat - 10/10"
Hi-Fi Choice - Editors Choice
This is an outstanding speaker that shows an all-round depth of talent that would be impressive even if the price were considerably higher. Its ability to remain transparent so that you can simply get on with enjoying the music is something that Q Acoustics can be very proud of, as it redenes expectations at the price. It’s comparatively unfussy about its environment or the electronics that integrate with it as part of a system and should be top of any shortlist if you’re looking to spend £4k on a oorstander.
