No more confusing series and parallel connections of voice coils and easier connection for multi-subwoofer systems.Neodymium motor with aluminum heatsink provides a heatsink for the motor's steel parts. Neodymium provides more magnetic energy in a smaller space, which reduces overall weight, and is inherintly magnetically shielded.3-inch diamter voice coils provides better thermal power handling than smaller sized voice coils.Vented Polepiece reduces air compression under the dustcap, which minimizes mechanical noise and provides more constant mechanical Q for reduced distortion.Medium Q Design provides great performance in sealed, vented or bandpass enclosures.
