Hey guys, its tax time and my pending refund check has me itching for something low and loud! I am trying to decide between a round or slotted port for this sub I will be using an RLP-18 and EP2500/BFD setup. My main question is this: Is there a noticiable difference in sound quality between a round (sonotube type) port and a slot port built into the box of the sub? Thinking of building something on the order of 36"x24"x36", so room isn't an issue for me, just want the best BOOM :bigsmile: for my buck. Thanks!
