HPE™ (Helmholtz Pressure Equalizer™) technology

The very nature of the Concept 50 tower design can introduce undesirable standing waves within the cabinet. By employing an HPE™ (Helmholtz Pressure Equalizer™) tube design, first launched in the Concept 500, pressure is converted to velocity to eliminate these performance-effecting vibrations and to help deliver the ideal frequency response.

Elegant design

Boasting the same sophisticated design lines and stunning, premium high gloss finish of the top-of-the-range 300 and 500 models, the new range retains the signature aluminium front baffle plate that made the original Concept speakers so iconic. The Concept 50 arrives in three striking lacquers: black, silver and white.

Gelcore™ technology

Introduced in the original Concept speaker, the Gelcore™ cabinet construction is designed to minimise high-frequency noise. A unique design comprised of a non-setting gel sandwiched between two individual layers, this specially developed adhesive dissipates high-frequency vibrations, generated by the moving drivers, into heat to maintain a focused audio performance.

Isolation suspension system

A variation on the hugely effective ‘isolation base’ principle first seen on Concept 300 means the Concept 50 have a suspension system in the form of a sprung baseplate. Two plates are separated by suspension ‘spheres’ that effectively isolates the cabinet from interference from external vibrations, providing tighter stereo imaging, while also bringing greater depth.

P2P™ (Point to Point™) technology

To keep the cabinet as rigid as possible, P2P™ (Point to Point™) internal bracing is employed. First introduced in the Concept 500, reinforcement is fitted to interior areas of the cabinet susceptible to low-end frequency reverberations.

Using Finite Element Analysis and laser interferometry to examine the performance of the cabinet down to a microscopic level, P2P™ bracing has been applied to the speaker cabinet.

Implemented this state-of-the-art technology, Q Acoustics have been able to identify and apply bracing to only the precise points of the cabinet that require additional support and unwanted energy is dissipated rather than transferred throughout the cabinet.

Bi-Wire Terminals

All models in the Concept series features Bi-Wire terminals on the rear of the cabinet. This means, using a compatible speaker cable, two pair of cables can be run from your power source (amplifer) to the speaker. One set of cables carries the high frequency signals, while the second pair transfers the mid/low frequencies.

The advantage of separating these frequencies through bi-wiring are two-fold: Intermodulation distortion caused by interactions between the high and low frequencies traveling down the cable can be minimised, with the result being noticeable improvement in the clarity of the mid-range.
