AD2108 D2


100W – 500W optimal power range / 800W max.
Thermally-coupled aluminum cone & dustcap.
Designed for use in small vented enclosures.
Engineered in the USA.

The 2100 series 8 employs a finely-tuned balance of damping and motor force to achieve high efficiency, offering exceptional versatility and performance in a variety of real-world functions:

Paired with a traditional (4th order) bass-reflex enclosure, the subwoofer’s output can be focused along a narrow bandwidth for use in sheer loudness / SPL applications. In a 6th order bass-reflex, the output can be spread along a wider frequency range, shifting emphasis onto sound quality with articulate delivery and highly controlled excursion.
