it seems like using a 6 in diameter tube for my port for my kicker 15 comps would be a little easier than the slot port as far as adjusting and tuning the box,if it didntsound just right.is the spl the same as long as you use the same port area,slot vs.tube.
spl will be the same.. slot port is usually easier IMO because usually you have to get into bends with pvc ports when your trying to tune a box low.. but if you have a spl box tuned high than yeah a pvc port is gonna be easier
