Silver Member Username: Kpa2727Post Number: 108 Registered: May-07 | i'm trying to figure out port length on a single bandpass for a 12 inch alpine type - r. it's a dual voice coil 4 ohm wired to 2 ohm. the fs is 29 hz the vas is 45 l {1.6ft} to the third. the box give me to ports each a foot in length. so i'm trying to find out how long to make each one to match my woofer. the link to the box is here http://www.qlogic.ws/products/q_enclosures_detail.jsp?classID=55&categoryID=228& groupID=7929 |

Try ~2cuft net tuned to 35hz for dialy...prolly sound 100% better than that prebuild bandpass. W/ that bandpass box, you are going to get a big peak in SPL at ~55-60hz and nearly nothing in the 30hz-50hz range. But if you are going to keep that bandpass, just leave the ports 12" long for daily. |
