Posted June 18, 200817 yr umm..i was looking recently at steve meade design for his current box and i was kinda fascinated o how a short port brings about such a response ..ive plotted some on winisd but could someone help on the type and how it works..to me it just seems like hole in the box...just sayin..help will be greatly appreciated..thanks .brandon
June 18, 200817 yr a shorter port means less port area..this reduces the damping factor and raises port velositybut it also saves space.....in an install like Steves (23,000w rms) SQ really isn't a factor..there is no such thing as SQ at thosepower levels..you just hold on for your life and hope the notes stop so you can breath the graph response would look the same..the difference would be the port velosity(percentage of Mach)

June 18, 200817 yr Don't forget that for the same tuning, if you don't change the port area and you make the box bigger, the port gets shorter. It's a big box..... So, that may be part of the confusion....OT, but West Indies? If so cool.... One of my best friend grew up there.... Edited June 18, 200817 yr by 95Honda
