Pioneer TS-SW2502S4 25cm Shallow-type 4Ω Single Voice Coil Sub (1200W)
Bigger cone, stronger bass, more power.
This 25cm subwoofer is just 7.8cm deep and has an oversized cone that produces louder bass than ever. Boost your car audio with 1200 Watts of pure, superior bass without losing too much space in your car.
Designed for enclosed use, the TS-SW2502S4 is fitted with a single oversized cone structure with double spiders to increase power handling and generate a more accurate, louder bass. The single cone helps keep the overall moving mass down at manageable levels, which is extremely important for efficiency and sound quality reasons.
A typical sub uses a damper to control the woofer’s cone excursion. Our double spiders are more efficient as they need less power to move the cone while producing superbly detailed and low distortion bass.
