Allegretto The Allegretto is a classic 2-way floor standing speaker with many improvements. With state-of-the-art drivers, cabinet and crossover, It's sound is homogeneous and free of coloration. The bass reaches very low frequencies and is very fast, with the midrange is warm and three-dimensional. The high-frequency range excels with outstanding detail resolution that never becomes intrusive or cool. The dynamics are very expressive and allow for very high volume playing. The Allegretto is highly musical and can be enjoyed without fatigue for many hours even on medium-priced equipment. Tweeter: The tweeter combines the best properties of metal domes and soft surrounds. A compact aluminum-magnesium dome is centered in a very wide fabric surround. This dome is very light and stiff, and only breaks up at levels far above what the human ear can discern. In addition to dampening the dome, the surround increases the radiating surface, resulting in a better efficiency level and lower cut-off frequency. Woofer/mid-range: For the midrange cone we chose the oldest of all membrane materials - paper. Over the last few decades, paper has evolved into a high-tech material with very diverse properties. It can be shaped into any form and is light, stiff and well dampened, all of which are desirable characteristics for a loudspeaker. The cone is formed with long wood fibers, which provide strong reinforcement reducing the typical break-up characteristics. Cabinet: Due to its low price and easy machine-ability, MDF (medium density fiberboard) has established itself as the most common material for speaker cabinets. For performance however, it is far from optimal. Because MDF is heavy and flexible, internal sound pressure turns the entire cabinet into a high distortion speaker. The Allegretto is built from 13-layer plywood costing five times more than MDF. The enclosure is very light and stiff with additional constrained layer damping to further prevent sound from exiting the cabinet walls. The net result is a cabinet that does not add its own coloration to the music. Crossover: A DC module in the crossovers tweeter section is used to smooth both the frequency and phase response. The crossover is also a symmetrical transitional filter, which begins with a slew rate of 12dB, but gradually increases to 24dB. Together with a baffle that is tilted away from the listener, the crossover puts the woofer/midrange and tweeter in phase at the crossover frequency, resulting in a linear transfer function. The net result is a 2-way speaker that performs like a point source. Technical data: Principle: 2 way bass reflex Tweeter: Ring radiator with 1in aluminum magnesium membrane and wide fabric surround.
