kevin chapman Posted March 13, 2019 Report Share Posted March 13, 2019 hello first post ever so sorry if im in the wrong place. i had a custom sub enclosure designed and on pdf file. really nice work i think. just concerned on where 2 ports meet. usually there is a divider in between the two ports. i asked him about it said it will work fine like that helped keep the port velocity down. first ever ported box build just want to make sure all is ok. can the great guys on this forum check out my enclosure and let me know what they think. it came with air speed and tfm graph but i have no idea what that stuff means. im running a cresendo 4000 watt rms 1 ohm amp. going in a dodge quad cab truck removing back seat. hope its all good cause im dying to get started. thanks Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted March 13, 2019 Report Share Posted March 13, 2019 That design looks really good to me. I completely agree with your designer, you don't need a divider between where the two ports come together and not having one there will result in better air flow. From what I see you should be good to go.

Triticum Agricolam Posted March 13, 2019 Report Share Posted March 13, 2019 There are a lot of materials that will work well for building an enclosure. In the end, your ability to make accurate cuts and fit things together well will have a lot more impact on how your box performs than what you build it out of. My preferred material for box building is 7 ply pine plywood. Its stiffer, lighter, less dusty, and holds screws better compared to MDF. Its more expensive though and can be hard to find. Places like Home Depot usually don't have it, but in some areas they do so its work a look. The specific stuff I use is called AraucoPly. If you can't get it a good pine plywood, the "birch" plywood that home centers have will be fine (even though its usually not real birch at all). You want to make sure whatever plywood you get has at least 7 plys, ideally of equal thickness. This rules out most construction grade plywoods. Or you can just use MDF and it will be fine too.
