Its cardioid design offers up to 12 dB of rear attenuation in Mono-Amp mode and up to 20 dB in Bi-Amp mode, without requiring complex external processing.

Housed in a robust birch plywood cabinet with a slim footprint, the Thunder-KSCARDIO412P combines

• high SPL performance with efficient space usage.
• 2x SpeakOn NL4 connectors and selectable mono/ bi-amp impedance ensure flexible integration and controlled bass.
