Add a subwoofer (optional)
Pick one model and choose how many units you'll run. Additional subs improve bass headroom and smoothness across seats.
Why we don't estimate a peak sub SPL number
Deep-bass output at your seats is dominated by things we can't model deterministically without a measurement: subwoofer placement, room modes, boundary reinforcement, crossover point, and how many subs you run. A single "peak dB" number would be misleading.
Instead, our recommendations look at driver size, amp power, and quantity relative to your room size, and the Prediction Confidence meter flags that sub response is un-modeled.
