HS7 Powered Studio Monitor Pair. "Newly Developed TransducersThe HS Series features newly developed transducers that achieve smooth response over a wide range of bandwidth. These transducers use a magnetic field design that regulates the flow of magnetic response to provide seamless sonic transitions. Each components materials and design were carefully re-examined, then optimized, to drastically improve the accuracy of signal reproduction throughout the audio spectrum. Tweeter The HS Series features a newly designed, highly efficient 1a dome tweeter that extends the usable frequency range considerably and delivers superb high-resolution sound. Utilizing a thick wave guide designed to minimize vibration the new tweeter is able to deliver smooth, distortion-free high end up to 30 kHz. Woofer With newly designed, ultra-responsive woofers that use large, carefully selected magnets, the HS-7 monitors produce low sound with a well-defined bottom end at any level. All of the components in these high-power woofers, including the woofer ring and the basket further contribute to the HS Series stunning bass while providing clear, accurate mids. The HS7 features a 6.5"" woofer. High Performance Amp HS Series speakers employ an amplifier unit perfectly matched to the transducers utilized in each model of the series. Featuring a bi-amp design with a separate dedicated amp for both the woofer and the tweeter, this amplifier unit ensures that each HS Series speaker consistently delivers high-resolution sound with exceptionally flat response across the sound spectrum. The HS7 features a60W power stage supplying the woofer and a 35W power stage supplying the tweeter. "
