NAD Monitor Series 4300 AM/FM Stereo Radio Audiophile Tuner - Works Great!. Will be properly packed for shipping in sturdy box with plenty of padding

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.

MONITOR AUDIO SILVER 300 6G FLOOR STANDING SPEAKERS (PAIR) SATIN WHITE. Tested to be fully functional. Besides some light scuffs / scratches which can barely be seen the pictures, these pair of speakers are in great condition. Speaker and Speaker grill cover only no other accessories. These will be packaged securely and signature required for safe delivery. See detailed pictures.  The Monitor Audio Silver 300 floorstander retains the familiar award-winning configuration of its predecessor, with several crucial improvements to drivers. The full three-way design delivers class-leading mid-range, while a pair of long-throw 6-inch bass drivers work together to produce incredible power from the tall, but slim cabinet design, making it the perfect choice for serious audiophile and AV installations.The three-way configuration allows each driver to be optimized to do a better job over a narrower frequency band; the only real way to deliver elevated performance in every respect. Superlatively natural mid-range comes courtesy of a dedicated 4-inch driver, specially designed with ‘under hung’ voice coil and motor system. This technique ensures the voice coil always remains in the magnetic gap under all conditions for demonstrably lower distortion than usually found at this level – an advance which can be immediately heard.
