[QUOTE="shredder2, post: 8614207, member: 674047"] Winisd shows that if you drop volume to 3.33ft3 net and with a 14.5" x 3.5" slot port 40" long... you'll actually be tuned to 29.86hz... and your port velocity will be 18 m/s with 750 watts of power... here's the curve... [IMG]https://snag.gy/bvEUcC.jpg[/IMG] [IMG]https://snag.gy/UW7EPu.jpg[/IMG] Who designed your box btw... those FU-15's do much better in a larger enclosure... this is a 5.5ft3 net tuned to 32hz... look at the low end ... wow... no wonder youre looking for more... just sayin' [IMG]https://snag.gy/ywtMiB.jpg[/IMG] Changing the port might be attractive to you but doing so will lead to problems in most cases... I did something similar with mine and used an external extension and lost a ton of spl and started smelling coils... Big low end usually takes space or a KILLER design if you are space limited... I cant tell you how many db's you'll lose... it's crazy to think anyone can use Winisd to tell you exactly... Winisd models your driver in a specific enclosure at a specific power level... the car environment is too complex to say for certain... but hey... maybe someone here will tell you what the graph says... lol Here is your current box... it's modeling up at a 33.69 tune and has too much port unless you are running a true 2.5K amp... [IMG]https://snag.gy/j7iaOs.jpg[/IMG] this is your port with a 2.5K amp... [IMG]https://snag.gy/epr7D1.jpg[/IMG] [/QUOTE]
