Description
This project I made using web designer, and I simulated in it a closed, a 6th order bandpass and a vented box for this woofer - all are buildable. All of the boxes are otimised for general music listening - at 20 Hz and higher frequencies acceptable group delay + acceptable vent air velocity + ideally power optimised using the stock parameters and Pe from SBL database + the woofer reaches but no overpasses it's Xmax. The port areas: vented - 72x314 mm, 6th order - low-ch.: 72x314 mm, high-ch.: 138x314 mm.
