 Thrilling Performance

Experience Definitive Technology’s signature sound even in spaces without the room for a full-sized speaker system. Whether playing music, movies, or video games, ProCinema Series speakers and systems envelop you in simple-to-setup, thrilling audio experience.

 Small Size, Big Audio Footprint

ProCinema Series speakers and systems share the same legendary engineering and technology as the best Definitive Technology floorstanding loudspeakers, custom-designed for smaller spaces.

 Your Cinema, Your Way

With a wide array of mix-and-match speaker choices and an all-in-one system option, your high end home cinema system is as simple as a click away, or as configurable as you need it to be.

 Tiny Titan

 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.

 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.
