|To determine the optimum box size and tuning for a ported enclosure system, you will need to know the following Theile/Small parameters for the driver: |
Note that this is only one of many possible alignments for a ported system with a given driver. Many types of alignments exist, each with its own particular advantages and disadvantages. This particular alignment will give you a maximally flat response within the system's passband, but it won't necessarily produce the best results with every driver, particularly those with very low Qts values (EBS alignments may work better with low-Qts drivers). You can use the "comparisons" section of the PORTED.XLS file provided on this page to derive a ported alignment that best suits your needs.
