quote from diysubwoofer.org:
"Where should I put the ports? Ports should be placed at least one diameter away from any adjacent walls. If this is not possible to do this, the tuning frequency for a given port length will be lower than that predicted by the equations, and this may adversely affect the results." Keld |
