SPL BiG is not only fun and intuitive to use—it also opens up unique creative possibilities for sound design. It enhances mixes with depth and impact without introducing any phase issues, delivering a bigger, bolder sound with ease.
🎛️ Go BiG or Go Home
Expanding the stereo image can give your tracks more depth, width, and presence, and has become a key technique for staying competitive in the loudness-driven world of modern music.
But phase issues have long been a challenge—often discouraging beginners and frustrating pros.
SPL BiG solves these problems by processing stereo input through a custom filtering network, avoiding phase shifts, cancellations, and unwanted artifacts when summed to mono.
The result? A powerful and clean stereo image that anyone can use with confidence. Go BiG—and get results.
Perfect for keyboards, strings, vocals—even full mixes—BiG allows you to dial in everything from subtle enhancements to extreme, creative stereo effects.
🎛️ Big Sound, Just Five Controls
SPL BiG makes it easy to achieve massive stereo width and depth using just three knobs and two switches—with zero phase issues.
Range Control – Precisely define the frequency range affected by the processing.
Stage Control – Adjust slope and bandwidth to shift focus in the stereo field, push elements forward, or deepen the soundstage.
Bigness Control – Blend processed and original signals using SPL’s proprietary method to create wide, balanced results dynamically.
