18 inch, 8ohm, 4" voice coil, 2000 watt, cast frame subwoofer made by Celestion for B-52.  One of the workhorses of the industry, these are found in many of the big name subwoofer cabinets out there.  1000 watt RMS long term thermal and mechanical power handling made possible via optimized double suspension and airflow vented magnet assembly offering dynamic heat dispersion.  Rain won't slow you down thanks to the glass loaded paper cone with weather-resistant impregnation.

Low Fs of 25Hz means you can really drag the bottom end out of these with extreme LF alignments.  High Bl and low Qts make it very capable as a folded horn woofer as well.
