“5-STARS. I was AMAZED by the sound that the Definitive Technology ProMonitor 800 produced. Even without a subwoofer, the sound was full and clear and had me shaking my head as to how such a small speaker could sound so large. The clarity was amazing and the bass was much deeper than expected. I will never purchase another brand of speaker again.”

ProMonitor 800 utilizes the same aluminum tweeter material as our top floorstanding speakers. Aluminum is light and stiff, making it the ideal material for a driver that must move beyond 20,000 times per second to reproduce the highest frequencies we can hear. You’ll hear clean, detailed highs that produce “air” and dimension in the room.

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.

ProMonitor 800 satellite speakers make a big splash from a small footprint with their innovative top-firing passive bass radiator. The 4.5” planar radiator, pressure-coupled to the BDSS woofer, significantly increases the bass-generating surface area. The result: room-friendly speakers with room-filling bass.

ProMonitor 800 is housed in a super-tough, anti-resonant PolyStone™ enclosure. The dense, acoustically inert material, along with PM800’s acoustically transparent grilles, means that you hear only what the artist intended—not the speaker cabinet.
