Art. No. 5914

Visaton VIB170AL - shown assembled with suggested cabinets, not supplied.

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.

Extract from HiFi Test: "The show put on by the VISATON speakers in the listening room was very impressive as we really did not expect such good bass qualities from such small speakers: clear, crisp and deep,.... We also liked the impulsiveness and dynamic properties,.... It was the VIB 170 AL, however, that took the title due to its extremely pleasant but lively voice reproduction coupled with excellent spatial qualities of the whole sound range. Thanks to the excellent design of the VIB 170 AL, this company, based in Haan, Germany, has managed to bridge that chasm between size and sound properties."

Extract from Klang & Ton: "The remarkable depth achieved by this 17 centimetre woofer was the most noticeable feature especially in view of the really crisp output. Despite this, the combination did not neglect the mid-range which it presented in an extremely pleasant, lively and dynamic manner."

Extract from Heimwerkertest DIY magazine: "This finely balanced sound experience left a deep impression on the testers. The remarkable depth achieved by this 14 centimetre AL 170 was a very noticeable feature. Despite this, the dainty-looking column speaker did not neglect the mid-range which it presented in an extremely pleasant, lively and dynamic manner. In terms of its spatial qualities and accuracy it must be a length ahead of others in that price range and can certainly be favourably compared in every respect with far more expensive ready-made high-quality speakers."

Assembly
The cabinet consists of 19 mm medium density fibreboard (MDF) or chipboard, stuck together as butt joints. Inside the speaker there are three reinforcing boards to prevent the cabinet resonating. Since the bass reflex tube can no longer be inserted through the bass speaker cut-out, due to the cabinet reinforcement, the base of the speaker is removable. To this end, a base and a frame mount are required. The frame is best manufactured from a board exactly the same size as the cross-sectional size of the cabinet, and with a cut-out in it. The base itself is exactly 1 mm smaller all round than the frame to enable it to be inserted with ease.

Internal Damping
The inner damping of the speaker uses 5 mats of damping material loosely placed inside the cabinet, but without interfering with the bass reflex tube. The frequency crossover unit is attached behind the bass cut-out on the rear cabinet wall.

Component Parts List for Each Box - Supplied with Kit
