Why Is the #Sa25m one of the best designed and engineered studio monitors in the world??? - Not because The SA25 is designed to work equally well as a near-field or mid-field monitor!!! Not Because it was designed and tested to meet a engineers real needs in a studio monitoring environment, but still very affordable. - The data and testing shows: We accomplished the goal of delivering Pure, Original Sound Without Any Additional Coloration. The Sa25m delivers a wide-range frequency response by employing six extraordinary drivers and DSP technology. It boasts a stable and balanced low-mid frequency response along with a defined mid and high-frequency response as well. Precise monitoring, high SPL output and broad bandwidth. The Sa25m are suitable for a wide variety of tasks, such as field monitoring, broadcast and TV control rooms commercial and home studios. The Minimum Diffraction Enclosure and advanced Directivity Control Waveguide technologies provide excellent frequency balance even in difficult acoustic environments. In order to generate powerful, ultra-crisp sound, there are six separate power amplifiers inside the SA25. Which drive six speakers respectively. The power amplifiers (specially designed for their drivers) are Class D with Sigma DSP built in and adopt switching power supply. #forthosewhowanttohearmore
