[QUOTE="foreman, post: 1048910, member: 550366"] Ok, i'm having some trouble with the box calculator. It says to make the port 1.75" wide, but even at 2" the air barely makes it out, and i know the sub should be louder and go way lower....I need some help. By the way, the sub is a Powerbass PR-12d and here are some specs: FS-36.39hz Qms-.53 Vas-35.68 liters Qes-.37 Re-3.81(dual 4 ohm coils) Xmax-18mm And PB recommends ported enclosure from 1.5-2.0 cubes..... I really want the right box for the sub, as the last 3 i built haven't been quite right and it still sounds decent...Can't wait to hear how the right one sounds....Anyone? [/QUOTE]
