Firenze-KS7
The Firenze-KS7 is a high-performance active subwoofer featuring 2x 21” neodymium magnet woofers with 5.31” voice coils, powered by Class D amplifiers. Its large, fully symmetrical ports ensure consistent back loading on the drivers, minimizing air turbulence and optimizing sound quality.
The rear panel includes balanced analog and digital AES3 inputs along with Ethernet connectivity, allowing full remote control via an integrated DSP. The subwoofer supports gradient/cardioid configurations and end-fire arrangements with up to 2 seconds of input delay and precise frequency shaping. Designed for flexibility, the Firenze-KS7 can be used as a single point source or in an arch array configuration, making it an all-encompassing solution for low-frequency reinforcement.
