From the Manufacturer
Enjoy a superior home theater audio performance without investing in expensive and space-consuming loudspeakers with the Definitive Technology ProCinema system, a line of compact satellite speakers, center channel speakers, and subwoofers that produces incredible sound at an affordable price. The biggest challenge in designing a sub/sat system is to engineer small satellites with a frequency response that extends low enough to blend properly with the subwoofer. Definitive Technologies overcame this challenge with the ProCinema series by engineering pressure-coupled medite passive radiators into the satellites and center channel speakers (the radiators are upward firing in the sats and side firing in the centers). These radiators dramatically improve the low frequency response while also delivering better linearity, improved transient response, and lower distortion. In addition, Definitive outfitted the speakers with BDSS technology, a patent-pending driver technology that couples a unique balanced double surround system--at both the apex and outer edge of the cone--with a precisely engineered central waveguide. BDSS produces a smoother response, greatly improved dynamic range, and dynamic stability, all essentials for elite home theater performance.

Sonically, the ProCinema speakers are a revelation in terms of producing incredible sound at an affordable price. Their imaging is absolutely boxless, spacious, and three-dimensional, with pinpoint specificity and localization when appropriate. Not only are they silky smooth with a "you are there" presence--unique at any price and unheard of in their price range--but they're capable of great subtlety as well. It all adds up to an immersive surround sound performance that excels whether you're watching movies or listening to music.

This particular speaker--the ProMonitor 800 satellite speaker--excels whether matched with a second ProMonitor 800 in a stereo setup or when teamed with three additional satellites in a surround sound system. Each speaker is equipped with a single 4.5-inch cast-basket bass/midrange driver, a single 4.5-inch pressure-driven planar low-frequency radiator, and a 1-inch pure aluminum dome tweeter. The drivers combine to produce ultra-smooth, high-definition clarity and a tremendous dynamic range, with a wide-ranging frequency response of 57 Hz to 30 kHz--a notable accomplishment for such a small speaker. The ProMonitor 800s sound particularly good when teamed with a ProSub subwoofer and a ProCenter center channel speaker, creating an immersive home theater environment capable of fitting in just about any room, including small living rooms and bedrooms. Available in high-gloss, hand-rubbed piano gloss black or gloss white, the ProMonitor 800 speakers offer several mounting options: shelf mounting via the unique tri-lobed base, wall mounting using the built-in keyhole mount or optional pivot mount, or stand mounting using an optional floor stand.

Choosing Definitive Technology Speakers for Your Home

Definitive Technology offers many quality speakers that are just right for your home. Which speaker, or set of speakers, you choose depends on how much you are willing to spend and which features you prioritize in a home theater environment. All of Definitive Technology's speakers are audiophile-engineered, designer-styled loudspeakers intended for musical reproduction and home theater systems of the highest quality. Thousands of man-hours of critical listening and engineering utilizing the most advanced computer loudspeaker development programs available--along with fundamental research at the world's most advanced loudspeaker research facility--have combined to create unmatched instruments for the reproduction of music or movies in your home.

	The ProSub 800 Subwoofer Speaker produces true state-of-the-art bass performance thanks to such features as a built-in, high-power, high-current amplifier, sophisticated electronic crossovers, and a high-definition 8-inch woofer with a polymer cone coupled to a single 8-inch infrasonic radiator. All of Definitive's ProSub powered subwoofers incorporate the company's patented, digitally coupled Infinite Power Source amplifiers--300 watts RMS in the case of the ProSub 800--with high-current direct coupled power supplies and discrete MOSFET output devices helping ensure perfect high-definition resolution and reproduction. The sub's construction quality is also topnotch, with only the highest-quality components used, including mil-spec glass epoxy circuit boards and precision resistors and capacitors. The powerful high-definition drivers, meanwhile, were specifically engineered by Definitive to deliver rock-solid low-distortion bass that reaches down to the lowest subsonic frequencies, with an outstanding quality of superior transient response unequaled in the world. Add in a continuously adjustable low-pass filter control--which allows you to choose a roll-off from 40 to 150 Hz for the high end of the subwoofer--and you have an ideal subwoofer to blend into your ProCinema system.

	ProCenter 1000 Center Channel Speaker: The ProCenter 1000 center channel speaker helps produce truly astounding dialogue when teamed with ProMonitor satellite speakers and a ProSub subwoofer. A center channel loudspeaker is the heavy lifter of your multichannel home theater system, as it delivers more than 50 percent of movie soundtrack information in a Dolby Digital 5.1 soundtrack mix. Fortunately, the ProCenter 1000 tackles this workload with ease thanks to its pair of 4.5-inch die-cast-basket bass/midrange drivers, which take the frequency response down to 47 Hz when teamed with the pair of 4.5-inch pressure-driven planar low-frequency radiators. The speaker also includes a 1-inch, wide-dispersion pure aluminum dome tweeter to handle the high frequencies, along with a resonant monocoque cabinet. The end result is a wide dynamic soundstage with an extra-large sweet spot, ensuring that everyone in the room hears every detail.

Customer Reviews

Crisp speakers
I am using these for my rear surround speakers and they sound great. Very crisp and clear sound. These came from ABT electronics. Very fast service! They arrived two days after I ordered them, even before the scheduled delivery date!!! Very happy with their service.

Wonderful, compact speaker
Very satisfied with the sound of these small speakers, and I would consider myself a very discerning audiophile. I combined them with the Pro Sub 800 for a wonderful sound in my home-office. If you listen to classical music, this set-up delivers fantastic value for sound.

Highly Recommended
A well designed, high quality product. Works perfectly in a 5.1 or 7.1 system in smaller rooms with a ProSub 800 and ProCenter 1000. Exceptional sound for the money.
