1point21gigawatts Posted April 8, 2020 Report Share Posted April 8, 2020 The ends of the ports are too close to the roof and the sound waves are fighting each other and the air isn’t flowing out of the enclosures properly. You need about 8 to 10 inches of breathing room. The sound waves and air are being dumped back through the port inside your enclosures instead of being dumped into your cabin. Causing your subwoofer closest to the port (which is eating instead of feeding) to have more excursion. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted April 8, 2020 Report Share Posted April 8, 2020 Just go ahead and spend the extra money and get a single ported enclosure built. Have the subs facing up like you already have them then have the port firing back towards the rear hatch. Go with a slot port on the bottom of the front or a big ass aero port, just one 10” would suffice. 3 subs on each side facing up and a 10” aero in the middle facing the rear hatch. You could build that yourself. But please make sure you keep that port internal and 8 to 10” away from the rear hatch. Plus you over did it on port diameter. the huge diameter in ratio to the subwoofers isnt making them subwoofers happy. It’s working against them instead of for them like you want. I know a guy that has 6 12s in a 6th order and is only using two 8” Aeros maybe 10” but they look like 8”. But since it’s a 6th order, one of them ports are the port connecting the two chambers. So if it were a regular ported enclosure he would only be using one 8” or 10” aero port. All you need is one 10” or 8” for your setup. You could do a 8” aero so you can have more breathing room and area for the enclosure. Then you can get away with having the port 6” away from the rear hatch door. Trust me and run with it. Much love and keep the bass pumpin! Make sure your calculations are precise too. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted April 8, 2020 Report Share Posted April 8, 2020 This is the website you need to use when calculating flared aero ports. And remember on port diameter you must put the precise diameter. An 8” port is really like 7” and some change in diameter. So note the actual diameter when you order the port. http://www.psp-inc.com/tools2.html “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted April 8, 2020 Report Share Posted April 8, 2020 This is the website you need to use for building the enclosure. But remember on this websites round port calculator that it’s intended for aero ports without flares so when using that round port calculator you have to add 1” to the calculated length if the aero has flares on both sides. 1/2” per side. https://www.the12volt.com/caraudio/boxcalcs.asp “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
