As the title states, I'm considering building the Zaph Audio SB12.3 but with a ported alignment for the woofer. The WinISD model says I can put a port in the same size box for an F3 of about 27 Hz instead of 37. Cone excursion looks good, port velocity looks good, I'm not really seeing a downside. I wanted to check if I'm missing anything, or maybe if something needs to change in e.g. the crossover design.
yes, of course. I really love woofers that work both ported and sealed in the same size enclosure, fun to compare the two. Double wigwams per port.
