Characteristics and sound properties
The VIB 170 AL is a slim-line 2-band column speaker using an AL 170 8 Ohm woofer and a 25 mm, G 25 FFL 8 Ohm textile dome tweeter. The 34 litre bass reflex cabinet produces a remarkably deep lower limiting frequency of only 25 Hz, but maintains its powerful, precise bass reproduction. The reason for this is the subwoofer AL 170 8 Ohm with its rear-vented spider and its long cone strokes. The flow-optimised bass reflex tube BR 25.50 is mounted at the rear of the cabinet to present the most ideal optical appearance, but can, if the cabinets are to be set close to a wall (closer than 10 cm), be moved to the front without any loss in quality.
The two 1 µF capacitors in conjunction with the 2.2 mH coil form a blocking circuit that effectively suppresses the resonance in the aluminium diaphragm generated typically by that material.
The VIB 170 AL is a compact speaker with well-balanced sound quality and clean-cut bass and impulse fidelity, providing excellent dynamic properties for a speaker of this size.
