Description
IMPULSE REF10 — Engineered for Fast, Controlled Low-Frequency Output
The IMPULSE REF10 is a compact 10-inch automotive subwoofer designed for strong bass output with accurate transient response. Its carbon-fiber cone combines low moving mass with high rigidity, helping the driver remain controlled during demanding low-frequency passages. A die-cast aluminum basket provides a stable mechanical platform and minimizes unwanted frame resonance.
The high-force motor structure delivers a BL factor of 20.29 T·m, providing firm electromagnetic control over the cone. With a 36 Hz free-air resonance and 25-liter equivalent compliance volume, the REF10 is well suited to space-conscious car-audio installations when used in a properly modeled enclosure.
Dual 4-ohm voice coils provide useful amplifier-matching flexibility. They can be connected in parallel for a 2-ohm final load or in series for an 8-ohm final load. Secure terminals help maintain a reliable, low-resistance connection at higher output levels.
