TIW 200 XS - 8 Ohm

Art. No. 1340

20 cm (8") High-end woofer specially for use as a small subwoofer. The extra-wide elastic cone, the long voice coil and particularly large magnet arrangement give this speaker extremely long excursion. Thanks to the multiple venting of the voice coil (pole piece hole, holes in the pole piece plate, cutouts in the aluminium diecast cone to vent the centring unit from behind) losses and flow noise are minimised. The capton voice coil carrier and the long voice coil enable the driver to withstand considerable loads. The diaphragm is a sandwich construction made up of layers of fibreglass and polyester fabric which makes it particularly rigid and low in resonance. These design features result in high level accuracy and excellent low-range bass imaging even in smaller cabinets.
