How do I choose a subwoofer?
Quick answer
Choose a subwoofer by matching its frequency response, SPL capability, and size to your venue and application, prioritizing low-end extension and power handling.
Selecting the right subwoofer starts with understanding your venue's size and acoustics. For small to medium rooms, a single 15-inch or 18-inch subwoofer with a frequency response down to 40 Hz may suffice. Larger venues or outdoor events require multiple high-output subwoofers, often in cardioid or end-fire arrays, to achieve deep bass (30 Hz and below) and even coverage.
Key specifications to evaluate include frequency response (the lower the better for deep bass), maximum SPL (peak output), and power handling (RMS and peak). Also consider the subwoofer's enclosure type: ported designs offer higher efficiency and output, while sealed enclosures provide tighter, more accurate bass. For portable systems, weight and rigging options matter.
At SSOUNDS, we engineer subwoofers with advanced DSP and amplifier integration to optimize performance. Our systems use proprietary low-distortion drivers and bass reflex tuning to deliver punchy, articulate low end. We recommend pairing subwoofers with compatible tops and using measurement tools to align phase and crossover for seamless integration.
Key things to consider
- Match subwoofer size and quantity to venue volume and desired low-frequency extension.
- Check frequency response (target 30-40 Hz for full-range), max SPL, and power handling.
- Choose enclosure type: ported for output, sealed for accuracy.
- Consider portability, rigging, and DSP/amplifier compatibility.
- Use proper alignment (phase, crossover) with main speakers for coherent sound.
