The EX12 is a 2-way high output, active, compact, fullrange speaker system. Design objectives for the EX12 were focused on the expansion of KV2 Audio’s primary philosophy of speakers systems with increased dynamic range, very high output and a consistent sound character no matter what the output level. The EX12 sets new levels of performance for compact cabinets achieved through the integration of new amplifier, transducer and electronic control technologies that are closely tied to a passion for taking performance to the next level. Amplifier power, electronic crossovers, phase alignment, equalization, time correction and speaker protection are integrated into the EX12’s amplifier module. On-board electronics ensures fast, easy set up and complete control. An improved version of KV2 Audio’s switch mode, current enhancing low frequency amplifier has been developed for the EX12. The new configuration improves overall system efficiency and increases output allowing passive radiation of heat to take place through a unique “fin-less” heat sink that can be placed in any position or direction. This ensures cool operation in horizontal or vertical applications. Additionally, the EX12 amplifier unit contains an internally located electric fan that is operated by a temperature sensing circuit which will slowly bring the fan online as required in extreme, high temperature situations. The EX12’s high frequency compression driver is powered and controlled by KV2 Audio’s standard low inter modulation distortion, Class A/B, push-pull, high and mid frequency amplifier design. Metal Oxide Silicon Field Effect Transistors (MOSFET) are used for the output stage and the compression driver coupled through a transformer balanced speaker output. The entire performance strategy for this type of design is based on producing the lowest inter modulation distortion possible and the highest audio quality in the critical mid and high operating bands.
