The finest amplifiers deserve to be paired with superior quality subwoofers and component systems. Thunder4000 subwoofers feature the same ALDS (Asymmetrical Linear Drive System), common to all MTX Audio Thunder subwoofers (the flat progressive spider, combined with the extended, vented pole piece). We've added some other touches to make sure these speakers perform way, way, past your expectations. The voice coil is wound on an Apical voice coil former for high power handling. The strontium ferrite magnet yields a highly efficient speaker (more efficient means better use of your amplifier power). The folded window basket is as durable as it is attractive.
As important as power handling, so is installation flexibility. Thunder4000 subwoofers are solid performers in virtually any enclosure - vented, bandpass, or small sealed.
These subwoofers will please all you fashion plates out there. Machine turned front and back plate with clear zinc plating (that zinc will repel corrosion) and a black foam surround. New injection-molded polystyrene gasket (it looks good, plus it's resistant to those bad UV rays). And the bright nickel connectors are good-looking and functional.
