They need all external enclosure dimensions and exact driver/port locations. Algorithms that evaluate it are slow and rather big for online implementation. It is therefore not a good idea to neglect this factor. If we use these simplified equations as a reference for the computation of SPL responses, it is worth noting that:Ī) Edge diffraction adds an 'error' of 3 to 6 dB over the range of 600 to 20Hz in an approximately uniform and definitely slowly changing manner. early 2015) are only an online computation of simple Thiele-Small-Margolis equations of the late seventies at which none of these factors was accounted for. Most software implementations available today (ie. For this they should include the following effects:ī) mutual coupling between bass drivers and ports,Ĭ) the formation of standing wave modes within the enclosure andĭ) the presence of sound absorbing material.įactors a,c and d have a strong impact and can't be neglected. These responses should be as accurate as possible. Ideally such a software should evaluate the SPL response of the bass drivers and the ports -if any- at a nearby reference point (usually on tweeter axis at 1m) for a frequency range of 20 to 1000Hz. The optimum amount of sound absorbing material is also expected to be determined. Such a geometry includes the box and the ports -if any- as well.

An enclosure design software is supposed to help a designer calculate the optimum dimensions of the predefined geometry of a speaker cabinet.
