It pairs with the Firenze-KH7P I line array element to form a complete full-range system. The sealed enclosure supports gradient, cardioid, and end-fire configurations when driven by the Kommander-KA208LIVE amplifier with its DSP, input delay of up to 2 seconds, and frequency shaping tools.
Frequently asked questions
Does the Firenze-KS7P I have a built-in amplifier?
No. It is a passive unit that requires an external amplifier. K-Array recommends pairing it with the Kommander-KA208LIVE, which provides dedicated DSP presets and CA-COM connectivity.
What enclosure design does the KS7P I use, and why does it matter?
It uses a sealed, fully closed enclosure. This eliminates port air turbulence and maintains consistent back-loading on both drivers, preserving low-frequency accuracy at high SPL levels.
Can the KS7P I be used outdoors?
Yes. The IP53 rating provides protection against dust and water spray, making the unit suitable for covered outdoor stages and touring environments.
