Combined System Notes (4 subs + 2 tops)

• The subs will dominate the 30–120 Hz band, freeing the NX985s to operate more linearly in their 120 Hz and above region.
• With 4 × subs, you multiply the low‑frequency headroom and pressure (adding ~6 dB more output in the sub band, in ideal coupling conditions).
• The matched dynamic ranges make alignment and crossover integration smoother, with fewer tonal discontinuities.
• The tour‑grade construction of both models ensures the rig handles load in real live / rental scenarios.
