Llewellyn, a student from Australia, came to me in December of 08' with a school project she had. It started with a simple 3-way tower design with a small sub, but due to cost it was trimmed down to what is below. The drivers of choice were 1x Peerless 811582 1” Tweeter; 1x Peerless 830887 5 ¼” Midwoofer; 2x Peerless 830880 5 ¼” Passive Radiator and 1x HiVi D8G 8" Woofer for the sub.
My role was to help her design a crossover and provide information on box volume, tuning frequency and port size. The original x-over design was set up with a band-pass filter on the midwoofer to protect it from large excursions. However, cost again forced us to eliminate that. In the end a simple 2-way 2nd/3rd Order x-over at 2800Hz was designed. And this being for a school project I generated a very detailed report on the x-over design process to aid her along with the project.
Final tweaks are still in progress. No photos just yet.
