In fact, the raw (unsmoothed) room curve was flat within ± 5 dB from 50 to 20,000 Hz, which is quite unusual in our experience.

The averaged room response of the left and right speakers was strikingly free from large peaks or dips. The audible differences were quite minor, and we concluded that the speakers are relatively insensitive to placement. Later we placed them directly on the floor about 18 inches from the wall. Since a tweeter only 24 inches from the floor would be at ear level only for listeners sitting on the floor (not our preferred location), we first installed the speakers on 7-inch stands a few inches from the wall. According to the instruction sheet, this placement puts the system close to the ear level of a seated listener, for optimum midrange and treble response, and also provides the flattest low-frequency response. Price: $350 a pair.Īdvent encourages experimentation in the placement of these speakers, although the Prodigy Towers are designed to be placed on the floor about 1 to 6 inches from the wall. The system's harmonic distortion with a 1-watt input level is rated as less than 0.8 percent above 80 Hz. The tweeter's output variation (dispersion) over a 30-degree angle, either vertical or horizontal, is rated as ± 1 dB. The rated sensitivity is 89 dB sound-pressure level (SPL) at 1 meter with a 2.8-volt input, and the speaker is recommended for use with amplifiers capable of delivering up to 75 watts continuous or 300 watts peak.Īdvent gives the frequency response of the Prodigy Tower as 45 to 23,000 Hz ☓ dB, with a useful lower limit of 37 Hz (where its output is - 8 dB). The nominal system impedance is 6 ohms, with a minimum of 4 ohms. At 3,000 Hz there is a crossover to a 3/4-inch, soft-dome tweeter (cooled and damped by ferrofluid) located near the top of the panel. The 8-inch, long-excursion woofer, which operates in a sealed enclosure, is located in the middle of the front panel, with the driver's center about 16 inches from the floor. The spring-loaded input connectors, recessed into the rear of the speaker, accept the stripped ends of speaker wires. With the black grille cloth in place, the speaker presents an all-black exterior except for the accents of light-colored wood. The top is covered by a solid piece of oiled pecan wood, and there's a matching trim plate on the bottom of the front panel. The cabinet, which appears to be made of 1/2-inch-thick fiberboard, is painted flat black on four sides.
Although its proportions probably justify the "Tower" name, it could be described more accurately as a minitower, for it will not dominate even the smallest room. The Advent Prodigy Tower, a compact, floor-standing two-way speaker system, measures 28-1/2 inches tall, 10-1/2 inches wide, and 8-7/8 inches deep and weighs 25-1/4 pounds.
