The ESX Audio QL series is a novelty from the manufacturer. It is the little brother of the QUANTUM QE flagship range, offering an even smaller size which again makes installation easier. The devices have the best D-Class technology with great efficiency and great sound quality! The layout of the amplifiers follows the line of QUANTUM amplifiers already published, and the QL range is a good extension of, for example, the X-DSP processor from the same manufacturer. All the amplifiers in the QUANTUM QL series are the same size, so you get a stylish whole!
The basics and connections are right when the device has automatic start, EPS (error protection systems) and adjustable crossover filters. High quality connections on both the power side and RCA connectors as well as at the speaker level. All QUANTUM QL series amplifiers also feature a compact, easy-to-place bass level control.
