Definitive Technology ProMonitor 800

Bring Definitive Technology’s legendary speaker technology to an infinite variety of environments with the ProMonitor 800. Boasting the heralded innovations and patented technologies of its much bigger brothers, the ProMonitor 800 is a versatile performer that fills any space with sensational sound, not with size.

  • Thrilling Performance
  • Small Size, Big Audio Footprint
  • Rich, Full Audio


Ferrofluid-Cooled Aluminum Tweeters for clean, clear highs

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.


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.


4.5” Passive Bass Radiator for bigger bass in a smaller package

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.


Wrapped in Performance anti resonant enclosures

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.


Stand & Mount Options for unlimited placement choices

ProMonitor 800 satellite speakers feature built-in, removable stands. They also feature a built-in keyhole mount for simple mounting with a single screw (not included). For ultimate versatility and placement options, choose either the optional ProMount 80 wall-mounting brackets or the optional ProStand 600/800 tall speaker stands.
