JAM Systems 4800W Big Bass Bundle
4 × SB118-33 Subwoofers + JAM X72 Amplifier

This complete big bass system is designed for serious low-frequency output with proven components, matched for efficiency, control, and reliability. The bundle combines four JAM Systems SB118-33 subwoofer cabinets, each loaded with a Beyma 18Lex1200Fe driver, powered by the JAM X72 high-performance Class-D amplifier.

The SB118-33 is a heavy-duty 18mm plywood subwoofer cabinet, tuned to 33 Hz for deep, controlled low-end. Extensive testing with a wide range of high-performance 18" drivers showed the Beyma 18Lex1200Fe delivering the highest sensitivity in this enclosure, producing exceptional output between 40 Hz and 100 Hz. In real-world use, this results in louder, more efficient bass from a 1200W driver than some higher-rated alternatives.

Powering the system is the JAM X72, a compact 1U professional amplifier designed for high efficiency and stable performance. Its Class-D output stage and LLC resonant power supply with active PFC provide consistent power delivery across global mains voltages, while a high damping factor ensures tight control over the subwoofers even at high output levels.

• 4 × JAM Systems SB118-33 subwoofer cabinets, 33 Hz tuning
