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. 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 cabinet, which appears to be made of 3/4" fiberboard, is Covered with Satin Black Vinyl Both Sides. 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. With the black grille cloth in place, the speaker presents a Classic Look with accents of light-colored wood. The spring-loaded input connectors, recessed into the rear of the speaker, accept the stripped ends of speaker wires.
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. 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 nominal system impedance is 6 ohms, with a minimum of 4 ohms. 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.
Advent gives the frequency response of the Prodigy Tower as 45 to 23,000 Hz ±3 dB, with a useful lower limit of 37 Hz (where its output is — 8 dB). The tweeter’s output variation (dispersion) over a 30-degree angle, either vertical or horizontal, is rated as ± 1 dB. The system’s harmonic distortion with a 1-watt input level is rated as less than 0.8 percent above 80 Hz.
