These Monster Bass Drivers rule in speed, sound quality, and SPL. Armed with a U.S. made massive 3.25” aluminum voice coil former with a flat wire wrapped edge wound style, it easily uses 1000 Watts RMS.
The SubZero also boasts its TCT (Turbine Cooled Transducer) coil and pole cooling technology, plus the PSP Terminal block that allows stereo and mono impedance changes just by flipping fuses. You can now have the perfect combination of looks, performance, reliability, longevity, and ease of installation. The SubZero from Earthquake Sound.
