The design provides controlled low-frequency reproduction, while the extended 23–130 Hz frequency range reveals information that smaller studio monitors cannot reproduce.\u003c\/p\u003e\n\u003cp\u003eThe integrated Class D amplifier delivers 220 W of continuous power and a maximum peak SPL of 119.9 dB. The front-firing bass reflex port extends low-frequency reproduction, reduces interaction with nearby room boundaries, and is shaped to minimise airflow noise.\u003c\/p\u003e\n\u003cp\u003eA four-position crossover control allows the S12.4 to be matched with KRK or third-party studio monitors. The bypass function, operated using an optional footswitch, disables the subwoofer and high-pass filter while sending a full-range signal to the monitors. This allows quick comparisons with and without the subwoofer’s contribution.\u003c\/p\u003e\n\u003cp\u003eLeft and right XLR, 1\/4-inch TRS, and RCA inputs and outputs allow the subwoofer to be integrated into different studio systems. A dedicated balanced 1\/4-inch TRS LFE input is also provided, while volume, input sensitivity, polarity, and ground-lift controls support accurate system setup.\u003c\/p\u003e\n\u003ch3\u003eMain
