KS7
describe
2 x 21" subwoofers with neodymium magnets and 6" voice coils are driven by powerful Class D amplifiers. The large port is designed to be perfectly symmetrical with the speaker, which means that the backload on the driver is consistent, even without port air turbulence. The rear panel provides balanced analog and digital AES3 inputs and an Ethernet connection for full remote control of the fully functional integrated DSP. With the Firenze-KS7, gradient/cardioid configurations and endfire arrangements are made easy, with up to 2 seconds of input delay and frequency shaping. The Firenze-KS7 is an all-inclusive subwoofer that can be used as a single point source or in a vaulted array configuration.
