Subwoofer

[Louis L]

This post-season class is intended to be primarily a fun construction project (who doesn't like BASS!). But in the spirit of STEM, there will still be science and engineering involved. The end goal is for each participant to build a custom subwoofer to suit their needs (size, cost, power handling, etc.)

[Louis L]

The schedule for this class is as follows:

Monday May 22 - Thursday May 25 (or shorter if we get it done sooner)
Note - you can't miss classes because each relies on the previous class. By the end of the week, each student will have a design that is custom designed for their specific needs.

   
• The science of sound reproduction
• Listening
• Designing a subwoofer for a system
• Run simulations

[Skip the week after due to graduation and other school activities. This also gives time for the parts we order to arrive]

Monday Jun 5 - Friday June 9 (or shorter if we get done sooner)

   
• Build, Test, Measure and Tweak.

Building a proper box can take some time. Hopefully we'll be able to finish the core of each box. Any additional finishing of the exterior, if not done in these 5 days, can be done at home.

Summary - Saty, Peter and Stav each built a subwoofer using 12 inch drivers. They each used a different driver plus a plate amp and an MDF box. Each had a volume over 3 cubic feet and dual vents and overall F3 (half power response) in the mid to upper 20's. In-room response should be very respectable. We played some sample music and rocked the workroom!
