A High Performance loudspeaker system featuring the SEAS Exotic W8 Woofer and T35 Tweeter Designed by Bjørn Borja and Håvard Sollien at the SEAS R&D laboratory.The Loudspeaker System described in this document was designed in parallel with the development of the SEAS Exotic W8 woofer and T35 tweeter. The goal was to develop a two-way loudspeaker using drivers with matching sensitivity and distortion, that would provide a smooth and extended frequency response in a cabinet of moderate size. The sensitivity of this system is higher than many systems of comparable configuration and size, making it ideal for use with low power valve amplifiers. Drive units This system uses the Exotic W8 woofer and T35 tweeter. A full description and technical specifications for these drivers available at the web- site www.seas.no. The Enclosure This system uses a vented cabinet with a net volume of 34 litres, and with a port tuning frequency of 40 Hz. It should be made from high quality MDF (medium density fibreboard). It is important that the cabinet sides are accurately cut, so they may be precisely joined together. Internal bracing and damping of structural resonances of the cabinet walls is also recommended. Details are provided in the cabinet drawing.
