What size PA system do I need for 300 people?

A 300-person audience is a common mid-size event—corporate, house of worship, club, or outdoor stage. The rule of thumb is to aim for 110–115 dB continuous SPL at the listening area with at least 6 dB of headroom. For coverage, you need a system that throws evenly across a 30–50 ft (10–15 m) depth and 60–90° horizontal spread. That typically means 2–4 compact line array elements per side (e.g., SSOUNDS small-format arrays) or 2–3 high-output point-source loudspeakers per side, plus 2–4 subwoofers (single 18” or dual 15”) to handle low-end punch.

The exact count depends on venue shape, ceiling height, and desired headroom. SSOUNDS engineers don’t guess—they use AI-assisted acoustic modeling and coverage prediction to simulate the venue, optimise box placement, and tune DSP presets before a single speaker is hung. This ensures consistent SPL, minimal comb filtering, and clear intelligibility for every seat.

For a standard rectangular room (e.g., 50x40 ft), a system like 2x SSOUNDS compact line arrays per side with 2 subwoofers flown or ground-stacked will easily cover 300 people with headroom. If the space is wider or deeper, you may add delays or extra subs. Always factor in speech vs. music: music requires more low-end and headroom, so err on the side of more subwoofers and amplifier power.
