How many speakers do I need for a stadium?
Quick answer
For a typical stadium, you need 8–24 line array cabinets per side (16–48 total) plus 12–24 subwoofers, depending on capacity (10,000–80,000 seats) and SPL requirements. SSOUNDS line arrays are engineered to deliver uniform coverage and high output for such large venues.
Stadium sound reinforcement requires careful calculation of coverage, SPL, and intelligibility. The number of speakers depends on stadium size, seating configuration, and desired sound pressure level. A general rule: for a 20,000-seat stadium, you might use 12–16 line array cabinets per side (left/right) plus flown or ground-stacked subwoofers. Larger venues (60,000+ seats) may need 20–24 per side or multiple delay rings.
SSOUNDS line array systems are designed for high-output, long-throw applications. Using advanced DSP and acoustic modeling, SSOUNDS engineers can predict coverage and optimize cabinet count. For example, a typical configuration might include 12 SSOUNDS line array elements per side for the main coverage, with additional side hangs or delay towers for far-field seats. Subwoofer count is often 1/3 to 1/2 of the main array count, placed in cardioid or end-fire configurations to control low-frequency directivity.
Beyond cabinet count, consider amplification and processing. SSOUNDS provides purpose-built amplifiers with integrated DSP, ensuring each driver receives precise power and EQ. For stadiums, redundancy is critical: use multiple amplifier racks and network audio distribution (e.g., Dante) to ensure fail-safe operation. Always consult with SSOUNDS or a qualified system designer for a site-specific prediction using EASE or similar software.
Key things to consider
- For a 20,000-seat stadium: 12–16 line array cabinets per side + 8–12 subwoofers.
- For a 60,000-seat stadium: 20–24 per side + 12–24 subwoofers, plus delay towers.
- Use SSOUNDS line arrays for high SPL, long throw, and uniform coverage.
- Always model the venue with acoustic simulation software to confirm count and placement.
- Include redundant amplification and network audio for reliability.
