The appearance of these new concept speakers is obviously influenced by the aesthetic design of the more expensive concepts 300 and 500, but the similarities are not only superficial. According to Q acoustics, many acoustic technologies that make these loudspeakers so successful have penetrated into the new conceptual models. These conceptual models also introduce "the latest audio innovation", thus realizing "real high-end home audio performance without high-end price labels". Most of the engineering work of Q acoustics is devoted to designing cabinets that are as quiet as possible, which is what the company is really good at. Many ultra-high-end speaker manufacturers go to extremes to control internal and external resonance, but it is unusual to see such a level of cabinet engineering at these prices. Q acoustics stated that its rugged and acoustically inert cabinet enables these speakers to provide "focused stereo imaging, accurate audio, and extended holographic sound field". Perhaps the most important technology here is the GELcore cabinet structure called Q acoustics. GELcore name refers to a specially developed non curing gel adhesive sandwiched between two layers of solid materials constituting the cabinet wall. It is reported that two separate layers buffered by this unique gel dissipate high-frequency vibration (generated by the driver) into heat, prevent resonance of the cabinet itself, and damage the audio performance of high-frequency focusing.

 

The three new concept outdoor speakers use GELcore technology in the whole cabinet. They also have an interesting isolation suspension system in the form of a spring base, which mimics the efficient "isolation base" originally developed for the flagship concept 300 rack speakers. The isolation base plate is composed of two independent plates separated by a "floating ball". The floating ball is designed to isolate the cabinet from interference caused by external vibration, such as interference from another speaker or subwoofer. According to Q acoustics, this will lead to closer stereoscopic imaging with greater depth and improved low-level detail. The crossover is also installed on the isolation base to protect sensitive electrical components from vibration and electromagnetic effects of the driver.

 

Loudest Bluetooth Speakers further benefit from the P2P (point-to-point) technology of Q acoustics, which applies internal support to reinforce some areas where the low-frequency reverberation of the speakers is most likely to cause serious damage. Using finite element analysis and laser interferometry, the engineering team checked the response of the cabinet "at the micro level" to determine the location where the problem vibration behavior is most likely to occur. The team then applies the support to the exact points on the cabinet that require additional reinforcement. The placement of this laser focusing bracket not only makes the cabinet more solid but also helps the cabinet to dissipate excess energy as heat instead of transferring it to other parts of the housing. For concept 30 vertical speakers and concept 90 center channel speakers, the above technologies are all necessary to achieve the performance that Q acoustics pursues in terms of cabinet muting. However, due to its slender design, the concept of a 50-floor stand has some unique challenges. Q acoustics said that the high panel speakers have a natural tendency to generate internal pressure in the cabinet, resulting in troublesome standing waves and reverberation. In order to prevent this annoying pressure from accumulating in the floor stand of the flagship concept 500, the company has developed a technology called Helmholtz voltage equalizer, which has been gradually extended to the new concept 50. Inside the cabinet, the pressure is "converted to speed" using specially designed Helmholtz equalizer (HPE) tubes. It is reported that this eliminates standing waves and reverberation, otherwise the frequency response will be changed, thus affecting performance.
