-If you get addicted to hifi speaker design you can try to
broaden your technical background by consulting our
book review section and -why not- browsing the
journals of the existing audio societies.
-You can also get closer to audio enthusiasts' community
through our list of worldwide audio websites,
web-magazines and discussion fora.
- This site is devoted to audio amateurs, hobbyists, researchers or students seeking a 'knowledge' base on hifi speaker system's design and implementation.
- Tutorials written in a practical way, book reviews, comparative studies on measurement software & equipment and hundreds of loudspeaker datasheets facilitate this intention.

Up to this point the key issues of the discussion were how a loudspeaker diaphragm oscillates and how this creates pressure waves. For the first issue a conventional model for diaphragm was used, that of the 'rigid piston'. For the second one, we assumed that a loudspeaker is surrounded by a very large plane (infinite baffle). These assumptions let us focus on diaphragm oscillation facing front and rear-side radiation loads. We presented two major speaker configurations: the Closed- and Vented-Box along with their amplitude, velocity and SPL responses. In this article we investigate how things change for a conically shaped non-rigid diaphragm of a real-life woofer driver. We also try to study how a loudspeaker emits sound waves off its conventional axis of radiation.

An enclosure design software is supposed to help a designer calculate the optimum dimensions of the predefined geometry of a speaker cabinet. Such a geometry includes the box and the ports -if any- as well. The optimum amount of sound absorbing material is also expected to be determined.
At this point it is essential to understand that the last two sections dealt with the task of shaping the SPL response of the acoustic branches separately in order to gain experience. We presented second order filter topologies for a two way speaker system. In this section we will start from the point where we left the acoustic branches and their components.

Generally speaking crossover design software combines loudspeaker SPL responses (that we have previously measured) with filter circuit data (also defined by us, the designers). This allows for the prediction (simulation) of overall speaker SPL responses which -in turn- verify whether design targets have been achieved or not.
