Model notes: Coverage radius assumes conical pattern: radius ≈ (mount height − ear height) × tan(θ/2). SPL uses sensitivity + 10·log10(P) − 20·log10(distance). Worst point ≈ center of cell (half spacing). Multiple-speaker overlap can add ~3 dB locally. Advisory only—confirm with manufacturer polar plots and EASE simulations.
