The finest amplifiers deserve to be paired with superior quality subwoofers and component systems. Thunder4000 subwoofers feature the same Asymmetrical Linear Drive System, common to all Thunder Loudspeakers (The Flat Progressive spider, combined with the extended, vented pole piece). The Voice Coil is wound on a Black Kapton former for high power handling. The strontium ferrite magnet yields a highly efficient speaker (more efficient means better use of your amplifier power). These subwoofers will please all you fashion plates out there. Black foam surround. Black poly dustcap with stealth logo. As important as power handling, so is installation flexibility. These Thunder4000 subwoofers are performers in virtually any enclosure (small sealed, bandpass, or vented). |
