91booster Posted March 23, 2023 Report Share Posted March 23, 2023 Ok guys I acquired a box it measures 46 wide by 24 tall and 24 deep now here’s the kicker it has a slot port of 44.5 by 6” by 6.75 deep and also comes with a port insert that closes port down to 10 wide 6 hi 6.75 deep I just stuffed the box with 2 15” solobaric L7’s I spoke to kicker they recommend making a cover and add 4 - 6” inch round ports at 13.75 inches long each now I’m no good with this box tuning so I’m asking you guys with port should I go with and it’s for a 06 tahoe build 3000 watt amp to power then. Thanks guys for all your help and advice. Quote Link to comment Share on other sites More sharing options...
Joe X Posted March 23, 2023 Report Share Posted March 23, 2023 The first box is 11.6 cubes tuned to 55 Hz 267 square inches of port area (insane). The adapter tunes low but has deficient port area of 60 square inches so it is a no go. The kicker suggestion is 11.7 cubes tuned to 38Hz 113 square inches of port area. To keep things simple I would do the kicker suggestion (4 6" ports) but longer length, 16" would get you to 36Hz tuning that is more reasonable, these ports are sold in 17" length so 1 inch external 16" internal would get you to 35Hz which is pretty decent. Other modifications would be more difficult to perform. Always ask around before buying a box, that builder obviously didn't know what he was doing.

91booster Posted March 23, 2023 Author Report Share Posted March 23, 2023 And also where can I buy such ports can I use 6”pvc pipe pieces Quote Link to comment Share on other sites More sharing options...
DizzleDizzle Posted March 23, 2023 Report Share Posted March 23, 2023 That's what I did with my last enclosure I bought the thin walled pvc and appropriate sized end cap plug the rubber kind with the bolt to tighten. I then extended the hardware with a long carriage bolt used the plug with extended bolt to mount the PVC to a drill then I spun the PVC while heating the end and got perfect flares. I also used PVC piece that had the bell end that slide overtop of another piece to make a joint. So I could then flare both ends separately and still fit the PVC into the enclosure cutouts once flared, before pairing them up. Then it's up to you if you want to glue the PVC together to make it permanent or just use some tape to make it adjustable and tunable.

NOTE: the brace and the board above should be removed. Edited March 24, 2023 by Joe X Quote Link to comment Share on other sites More sharing options...
91booster Posted March 26, 2023 Author Report Share Posted March 26, 2023 Awesome ideas guys I will whip up a fix and post up. Thank you all I even considered just sealing the port up but I’ll be tinkering soon 👍 Quote Link to comment Share on other sites More sharing options...
Joe X Posted March 27, 2023 Report Share Posted March 27, 2023 If you want to go with 4 6" round ports just make them as long as possible as long as there is 6" clearance on either side for each port, PVC pipe is widely available, you can get it at Home Depot or Lowe's. If you want to go with branded round ports, you can get them at parts express: https://www.parts-express.com/Precision-Port-6-Flared-Port-Tube-Kit-268-354?quantity=1 They need to be installed above the current port because the flares will not fit. Round ports are a great solution is just that you have to pay for them and the branded ones are very expensive. Quote Link to comment Share on other sites More sharing options...
91booster Posted March 29, 2023 Author Report Share Posted March 29, 2023 Yes I got 4 6” abs plastic pipe in 24” lengths . I was going to leave them around 18” with at least a foot inside box I’ll shorten if need be but I’m guessing 18” will get low 30hz range and I don’t wanna make my box to small filling with port again this isn’t my field any input is helpful .

Joe X Posted March 30, 2023 Report Share Posted March 30, 2023 Those two subs will work perfect in 10 cubic feet, even with the ports fully inside you are well above that so don't worry about that, as before keep clearance of 6" to either end of the ports and also you may need a brace because they are rather long and they don't come with screws unlike the PSP ones.
