How wide is your port? I can figure out your total port area just need your port width.

Port width is 3" and Height is 14.5 if im not mistaken. Got me second guessing this DC... Your the 1st person to have any subjective input, but the fact that you have used them in what looks to be a very nice box, says alot, so thanks for that.

So to better visualise your enclosure and how its performing I punched in your box stats in Winisd. The green line represents your current box with the SA-15. Since DC audio doesn't list T/S parameters for the LVL 4's I went with the Sundown Zv.3 and notice how flat it plays and doesn't seem to get loud up until 40hz but to me looks quiet
If you were to build a new box for the SA-15 that is 36" wide 16" high and 18.5" depth but instead of a slot port went with a single 6" diameter by 15" length aeroport the final specs would be 4.5 cubic ft. tuned to 29hz and thats what the blue line represents. Between 25hz - 40hz you gain alot of output especially 40hz where its almost +3db which to the human ear is equivalent to almost twice as loud. HTH

Damn you gramser57!!!! LMAO!! Where the hell were you when i was tryin to build a box for my 2 15's?? lol.... Seriously though, thanks a bunch for your help. Your input has been both eye opening and informative. Unfortunately i read your last post too late as i had already placed my order for the lvl 4. Friend of mine was also making a purchase and got us an AWSOME deal. Now i know im getting ahead of myself but just wanna cover my bases. CANNOT find a decent box builder locally. Was hoping you could help me with a box build for 2 SA-15's?? Can provide you with all the info you need if you would be willing. Can pm you my email and we can chat.... Also would like to thank all who have submitted replies to this thread. Nice to know there is somwhere to go for help when needed. Just in case this DC doesn't work out I will still have my 15's to try a build for again. Just gonna have to take 1 back from my step son and give him the DC but he will be fine...lol
