The highly sturdy diecast basket, which is also extremely well vented, is a commendable feature of the TIW 200 XS by Visaton. The large-format rear venting holes under the damper, which effectively prevent compression distortion on longer cone excursion, are a laudable highlight. The issue of venting runs through the entire construction of the drivers. The idea of the pole piece hole is to vent the inside of the TIW and this function is rounded off by a ring of smaller holes in the back plate so that no cavity in the driver is left unvented. As regards the quality of materials, no corners have been cut. Visaton has included a high-quality elastic cone and the diaphragm and dustcap are not injection moulded pieces but genuine sandwich constructions made up of two polyester layers around a core of fibre glass webbing. The voice coil is coiled around a capton core with a height of no less than 30 mm. Our lab tests showed that the baffle resonance levels of the TIW (2,100 Hz) are well damped. In the distortion graph, the corresponding K3 peak is at 700 Hz - at a very reassuringly low level. Visaton recommend using this driver as a subwoofer but, in view of the very good results we achieved, the TIW should also be equally at home in a multiple-driver system - it would no doubt make a very good three-way woofer. It feels most at home in a bass reflex cabinet and, here, any number of solutions are possible from a compact, unobtrusive subwoofer to a full-blown deep bass woofer with a 70-Iitre cabinet. From the point of view of value-for-money, the excellent craftsmanship and well tuned technical characteristics definitely make it worth the 125 euros we paid.
