What if any is the difference between a regular slot port and these black cirlce ones (not sure what you call them). do they sound better or anything...... less port noise?
well some people think a slot gets deep or lower, and they tend to have less port noise, depending on size. but i dont think the black flared ports have much noise either...but i like the way they look....so i guess it what ever you like better...
close to the same.. with round ports you can save on box volume.. with slot ports you can save on money and difficulty to build.. either of the two are not that hard to do but slot ports seem easier but take more box volume
