EM Audio Mini Team 12” Subwoofer (3.5K Series)

The EM Audio Mini Team 12” proves that you don’t need a massive cone to make massive noise. Built on the same philosophy as our larger Team platforms, this 12” is a compact powerhouse designed for extreme output, tight response, and daily reliability.

This isn’t your average 12. The Mini Team 12 was engineered for builders who want serious low-end performance in a smaller footprint—perfect for tight builds, high-output daily systems, and competitive setups where efficiency and control matter.

Rated at a conservative 3,500 watts RMS, this sub is built to take real power and deliver consistent performance without breaking down. From the motor to the soft parts, every component was carefully selected and tested to handle abuse while maintaining clean, accurate bass.

At its core, the Mini Team 12 features a high-efficiency motor structure designed to deliver strong motor force and excellent control across the entire stroke. Paired with a 3” (86mm) 8-layer American-made aluminum flat wound PE voice coil, this sub offers impressive thermal handling and output capability for its size.

The 10” progressive spider pack keeps the moving assembly stable and centered during extreme excursion, allowing the sub to stay tight and controlled even when pushed hard. Combined with EM Audio’s advanced soft parts, this results in smooth low-end response with minimal distortion.

Cooling is handled through pole venting and perimeter voice coil cooling, helping reduce heat buildup and power compression so you can play longer and harder.

The heavy-duty TI frame and ventilated structure improve airflow and durability, ensuring the Mini Team 12 holds up under serious daily abuse.

Small footprint. Big attitude. Real power.

If you’re looking for a 12 that can keep up with larger setups and still hit hard, the Mini Team 12 is built for you.

A 5 layer 10″ suspension was used to keep everything align during extreme high excursion. Pole vent cooling was added to keep pressure off the dust cap on high excursion. And perimeter rear direct coil cooling to help keep this beast cooled during high power handling. The powerful magnet assembly we use assures high flux concentration. The ventilated basket designed between the spider and magnet structure significantly improves thermal connection and heat dissipation, further increasing power handling and lowering power compression.
