In a vented enclosure sized within.7–1.1 cubic feet per sub and tuned to 32–38 Hz, this NST8 yields strong, extendable bass with controlled cone motion. The 159 oz motor and 15.5 each-way XMAX support substantial excursion, helping bass reach deeper than typical 8" budget subs when paired with an appropriate amplifier. The epoxy-coated 2.5" voice coil enhances durability during high-signal operation, while the dual 2-ohm configuration offers wiring flexibility to fit common car audio layouts. For best results, use a ported enclosure within the recommended volume and note that sealed enclosures are not advised for this model.
