In this design, only the front board is angled.
When flush mounted to a vertical piece of wood, the woofer will be a couple of inches behind the mid & tweeter. In an ideal speaker configuration, the back of each speaker cone lines up vertically.
#Speaker enclosure design basics driver#
Notice that the chamber for the midrange driver isn't the full depth of the speaker. Note: the woofer will be ported in all of these design options, even when it isn't shown.
#Speaker enclosure design basics drivers#
The EBP of our midrange and woofer drivers are calculated as:īoth values are well above 90 and call for Ported Enclosures. The tweeter in our example is already sealed and doesn't require an enclosure. Between 50 & 90 either type would work.Įfficiency Bandwidth Product (EBP) = Free Air Resonance (Fs) / Driver Electrical "Q" (Qes) Above 90~100 and a Ported Enclosure is recommended. If the EBP is less than 50, then a Sealed Enclosure is recommended. Ported calculator uses the formula below. Ported Speaker Box Calculator to determine if a sealed or a ported enclosure should be used. (with specifications provided by the manufacturer) are: The mid is 4" and the woofer is 6.5" in size, but this system is still capable of These 3 drivers might be smaller than what is expected of a typical 3-way system. This design is old and the characteristics of these drivers have since changed and/or been discontinued. The same 3 used on the Crossover Tutorial. You should also review the Speaker Building Guideįor this example, I picked 3 ScanSpeak drivers for a 3-way speaker. This example of a designing a speaker box makes use of many of the calculators found on Designing and Building a Speaker Box Example
