In the second year of Electronics Engineering Technology, I built a subwoofer kit as part of my Industrial Techniques course. I bought two kits and put alot of time and effort into making this a great project. I simulated the circuit and analyzed how it works. I encorporated additional HPF and LPF features by modifying the design of the filtering circuitry. Schematics were generated using Proteus ISIS and the PCB layout was replicated using Proteus ARES. Boards were built by following a structured step by step testing process. Testing and troubleshooting was conducted using a signal generator, oscilloscope and a DMM.

Having populated two boards, I had to design and build two enclosures. Since the enclosure design is the most important part of any subwoofer/speaker, I invested much time into researching and engineering an ideal enclosure to reach the ultimate quality. Enclosure was tuned to an incredibly low frequency by using PVC pipes and adapters to interconnect the pipes starting from the port hole. In between each layer of piping lies fiberglass to eliminate vibration and dampen the bass hits. The box was built using MDF wood and the finish was achieved using iron-on veneer, cherry red stain and clear coats.
