Plugging an Aeroport

[jmgb4 10+ year member]

Well I have decided to go a little on the small side for my port area and get a 6" aeroport. Now my question is is there a way to plug one? I will have two for SPL and one for daily pounding / listening. One open is for 33hz while two is for 48....

If I cant do this then I need to re-design once again. I have a 3.75 cubic foot box and I wont be able to fit 8" tubes in my trunk and get the tuning I want. The 6" aeroports are a "little" too small but better than just using 6" pvc. The only issue is plugging one.

I was thinking of mounting them both flush with the edge of the box and having a bigger wooden disk with a rubber gasket on the inside of it. I would secure it using nuts and bolts already drilled and glued into the box. The only problem is is when the glue wears off on the bolt, it will keep on spinning and I wont be able to seal that port 100% - also if the bolt ever rattles into the box I am done for... Both of these issues would make the box useless for daily pounding / listening.

Ideas? Suggestions?

you can build a cap out of mdf and use t/hurricane nuts to hold it in place and use a gasket of some sort to seal it.

I googled hurricane nut and I still have no idea what it is or how it works.

t-nut. its a nut/washer combo. but on the washer it has prongs that stick into the wood. you drill an oversized hole and put it in.

t-nuts

use these instead of trying to glue a nut to the mdf

Ive tried t-nuts before. They were awesome, until I needed to actually remove the bolts. The t-nuts simply popped out of the wood when trying to loosen the bolts, which made removing the speakers quite difficult. The density of mdf makes it hard for a standard t-nut to get a satisfactory grip. The barbed nuts might work better though, never tried them.

That was my experience with t-nuts in birch too. When I went to pull the sub, it was no fun because the t-nut loosened from the wood and just spun in place. I had to use a dang pry bar to hold constant pressure on each individual t-nut.

you guys dont glue the t nuts in huh

I think thats the ticket, for those or the huricane nuts, put some glue on them and tap in with a hammer

Actually I did BUT I had 2 pieces of that top layer of birch that just spun into the T-nut on at least 3 holes. Made sub removal a beeitch!

Now I will only use hurricane nuts.

i remember seeing aero-port plugs, so you don't have to remove it. simply install the plug(which fills the whole length of the port) and you are done. remove to compete.

Look into those pipe plugs that are used in the plumbing trade.

Hurricane nuts are meant to be threaded in bro not pounded with a hammer. That's why they have the hex opening, so you can thread them in using an allen (hex) wrench.

I love hurricane nuts, I've NEVER had one come loose. The only drawback to them is you now have a machine thread to fit into, which means your holes HAVE to be precise, if your holes are off a bit or not straight through the wood it becomes very difficult to thread your bolts in.
