[QUOTE="jolly_26, post: 7555892, member: 635986"] Yeah that port on my box gives an area of 14.1 square inches, and a 4" aeroport would give about 12.5. This woofer should get away with 12 square inches easily, and with 31x250 I could have kept within the 1:9 and had exactly 12 square inches. This means the smaller port dimension, 31, shouldn't cause any port noise, and extending the width of the port to 294 would only decrease the velocity of the port, correct? This is what I based my "I should be fine to step outside that ratio" thinking on. I had also read that in doing so you may lower the tuning of the box slightly, which would have been handy, so I went ahead with it. Hopefully pro-rabbit can let me know if my thinking on this matter is correct. And sorry for the mess of metric and imperial together! [/QUOTE]
