For ported boxes, I learned that the placement and tuning of the ports could affect sound quality. I researched different port designs and their effects on bass response. This knowledge helped me in choosing a box that would maximize the performance of my subwoofers.

Budget Considerations

Finally, I had to set a budget for my subwoofer box. I found that prices varied widely based on size, material, and design. I made sure to balance quality with affordability, ensuring that I got the best value for my investment.
