Q Acoustics Pack concept 50 black lacquered

An elegant design

Featuring the same design lines and high-end finish as the flagship Concept 300 and 500 models, the new range retains the aluminum front baffle that made the original Concept speakers so iconic.

Gelcore technology

A process introduced with the original Concept speaker series, the Gelcore cabinet construction is designed to minimize high-frequency noise. A unique design consisting of a non-hardening gel sandwiched between two individual layers, this specially developed adhesive dissipates high-frequency vibrations generated by the moving speakers into heat to maintain very high-performance audio reproduction.

Isolation suspension system

A variation on the highly effective “isolation base” principle first seen on the Concept 500 speaker, meaning the new concept range features a suspension system in the form of a spring baseplate. Two plates are separated by suspension “spheres” that effectively isolate the cabinet from external vibration interference, resulting in a more precise stereo image while providing greater depth.

P2P (Point to Point) technology

To make the cabinet as rigid as possible, an internal P2P (Point to Point) reinforcement is employed. First introduced in the Concept 500 speaker, this reinforcement is installed in the interior areas of the cabinet that are likely to experience low-frequency reverberations.
