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.
