4.5” BDSS™ Woofer in a Cast Basket for smooth, dynamic midrange and bass
ProMonitor 800’s 4.5” woofer features our patented Balanced Double Surround System (BDSS™). The dual surrounds allow for greater cone excursion, enabling the ProMonitor 800 woofer to produce the bass of a larger driver, while remaining the perfect size for detailed, silky-smooth midrange. And the cast basket provides a muscular, anti-resonant frame for the additional cone excursion.
