Polk Audio’s three-piece Reference Monitor speaker system, the RM-3000, consists of two small satellite speakers and a subwoofer module. Although this general configuration is currently enjoying increased popularity, Polk’s version differs from the others in many of its design details.Each of the satellite speakers is a miniature two-way system with a 3-1/2-inch “woofer” operating above 200 Hz and crossing over at approximately 4,000 Hz to a 3/4-inch dome tweeter. The tweeter is protected against burnout by an internal auto reset protection device that cuts off its signal until the power has been reduced to a safe level. The tweeter is stepped back about 1-1/4 inches from the plane of the woofer to provide proper time alignment of the outputs of the two drivers.The satellite enclosure is made of a high-density, non-resonant polymer aggregate similar to the material used for high-quality kitchen countertops. The smooth, glassy exterior is resistant to physical damage, and each of the satellites— which measure only 6-3/4 inches high, 4-1/4 inches wide, and 5 inches deep, including the molded plastic grilles—weighs a surprisingly heavy 4-1/2 pounds. The crossovers contain second-order low-pass and high-pass sections designed to complement the time alignment of the drivers. In addition to its crossover network, each satellite also contains a 200-hz high-pass filter that protects it from being damaged by high-level low-frequency signals.The subwoofer contains two 6-1/2-inch cone drivers, each driven by one stereo channel. For each channel, the appropriate satellite, the subwoofer, and the amplifier are simply wired in parallel. The subwoofer enclosure, which measures 20-1/4 inches wide, 13 inches deep, and 10 inches high, is supported 2 inches above the floor on four rubber feet. Its interior is divided into two separate sections o? different volumes, with the drivers mounted on the dividing partition. The rear surfaces of the two driver cones face the sealed volume, which provides the necessary stiffness for their proper operation. In the other section, the pressure generated by the drivers is coupled to a 10-inch passive radiator mounted on the bottom of the cabinet, facing the floor. According to Polk, the passive-radiator coupling reproduces the low frequencies more efficiently than a simple port radiator, while the mass and size of the passive cone (called the “sub-bass” radiator) attenuate the higher frequencies, providing an 18-dB-per-octave rolloff matching the low-frequency rolloff of the satellites. Since each driver is connected to one of the stereo channels, the two channels are acoustically blended throughout the subwoofer’s operating frequency range (which contains virtually no directional information). Although the subwoofer’s response rolls off naturally above 170 Hz, the unit also contains a first-order low-pass filter to avoid wasting amplifier power above its operating range.

3-Way Reference Standard Speakers featuring Infinite Slope Technology

*This unit is only six months old. It was purchased and installed in a rack, used for six months and is now being sold as our client decided to move to the country. MSRP $31,250 THE ULTIMATE EXPERIENCE IN IMMERSIVE AUDIOPeerless in performance, configurability and sound quality, the Altitude32 remains the unchallenged reference processor for Immersive home theater systems. Nothing has been left to chance: high-channel count, huge processing power and exclusive patented technologies unleash the full potential of immersive sound, enabling all formats and the widest range of speaker layouts.UPGRADABLE BY DESIGNThe hardware architecture of the Altitude32, unique among home theater processors, challenges the concept of obsolescence by enabling the integration of new technologies, new features, and product upgrades through a pure software implementation provided at no cost to Altitude owners. This is a truly sustainable product that gets better over time with the introduction of new features and a scalable, modular hardware design that enables easy system expansion up to the full channel counts of home Atmos and DTS:X and to a maximum of 64 outputs.Its revolutionary hardware architecture runs not on the multiple sets of DSPs found on other processors but instead on a single multi-core Intel hardware platform and TrinnovOS operating system. This enables Trinnov to bring new technologies and features to market months and years ahead of the competition.
