This design however is more efficient and results in an increase of bass output at certain frequencies. Although vented enclosure has an output advantage at some frequencies, it also has a steeper roll off, which will only affect bass frequencies below port tun- ing.
- Page 8 TIPS TO GET THE MOST OUT OF YOUR S SERIES WOOFER Your PowerBass Autosound subwoofer has been meticulously engineered and designed to handle high power musical reproduction. Despite their rugged construction, it is possible to damage your speaker if they are improperly used. In general, you will hear distortion as a warning before any damage occurs. If you hear distortion in your system, immediately reduce the musical level to the point where the sound retains its clarity.
- Page 9 BOX CONSTRUCTION (SEALED OR VENTED): The material used for enclosure walls should be solid, dense and free of voids or warps. Your enclosure should be made ¾” or 19mm material, Finland or Baltic birch type plywood is recommended where the enclosure will be transported frequently. High- density fiberboard - MDF (not chip board) can be used on permanently installed systems.
