Visaton Speaker Kit - CT Center 81
Art. No. 8405
Visaton CT Center 81 - shown assembled with suggested cabinets, not supplied.
Characteristics and Sound Properties
The CT CENTER 81 is a compact, enclosed 3-way system with well-balanced sound quality and complete magnetic shielding, as required for example if positioned close to a TV or PC. Inside the cabinet, we use magnetically shielded speakers, types F 8 SC - 8 Ohm (8 cm full-range) and SC 5 - 8 Ohm (10 mm tweeter) and the complete speaker then meets the shielding requirements of the THX® regulations (3-Gaussian curve). The asymmetric design of the front baffle and of the crossover unit provide good omnidirectional sound distribution both vertically and horizontally. It is possible to install the speakers in the upright position, as is usual for multimedia systems, or lying down on top of a TV, as is usual with surround systems.
In terms of sound quality, the CT CENTER 81 produces clear-cut sound, well removed from the speakers, but with remarkably well-formed bass reproduction for a system of this size.

Assembly
The construction of the CT CENTER 81 speakers is very simple, since it is only necessary to glue 6 boards together (flush). However, it is essential to work accurately since the front grille will not fit in the opening if the tolerances are too great. The grille has the following outer dimensions: 85 x 220 mm.
Internal Damping
Half a mat of damping material is loosely pushed into the cabinet.
