Humbol Posted September 22, 2020 Author Report Share Posted September 22, 2020 4 hours ago, Backwoods said: I agree with 1.21giga. Even the pre/pro fab from D4S for a single 15 is 300 bucks.... For that price you can get a box custom built... And for that SUV, i would go with Sub up and port back to the rear if you had the room for it. But using your current box is a possibility... But i would not be surprised if that enclosure is tuned a bit high if it was custom built for that 3515 by someone that had experience with the older non ESP DD subs... Back in the day is was very common to tune boxes for those subs around 40hz. And they worked in a WIDE range of sizes... Even the newer 15s are listed from 3-6 cubes per sub... Thats a BIG variance. Not all subs work well in that big of a variance. Its always best to have a box built for the sub and vehicle it will be in... But in order to pick the perfect sub for that box we would need to know tuning, port volume, and net volume. If you have any tools and experience working with wood you could likely build you own. 1.21 is great at designing boxes and if you sweet talk him he may help you out if he has the time. If not, there are a lot of builders that sell plans, designs, made for your vehicle, sub, and power. There is also builders that sell flat pack/ glue and screw boxes... Meaning you order a box that comes with the wood all precut and you just assemble it, which makes the price cheaper than a built box and reduces shipping charges... Or you could order a completely built box. Will do. Thanks!

Humbol Posted September 22, 2020 Author Report Share Posted September 22, 2020 Finally got the time to measure the box and this is what it was.

1point21gigawatts Posted September 23, 2020 Report Share Posted September 23, 2020 Are you sure that the port walls overlap like that or could it be vise versa and the smaller port wall overlaps the bigger port wall instead? And I need to know the width of the port slot. “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 September 23, 2020 Report Share Posted September 23, 2020 Reach in the enclosure and feel the corner and feel how it overlaps to make sure, because I can’t tell when it comes to them pictures. “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 September 23, 2020 Report Share Posted September 23, 2020 I just though about it and don’t worry about how the port walls overlap I just need to know is it 3” from the inside corner (green line) or 3” from the outside corner (orange line)? “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 September 23, 2020 Report Share Posted September 23, 2020 Backwoods was right. No matter if it’s 3” from the inside corner or outside corner it would be tuned at 41.4hz-41.63hz. “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 September 23, 2020 Report Share Posted September 23, 2020 And if it’s 3” to the inside corner then the net volume before subwoofer displacements is 3.68 cubic feet and if it’s 3” to the outside corner then the net volume before subwoofer displacement is 3.73 cubic feet. “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...
