For everyone who is always asking how to make homemade towerspeakers, here are some that I made from aluminum tubing with a fiberglass backing to seal the otherside. It was tricking to make the aluminum square tubing to mount to the tower but it is possible. Let me know if anyone is interested in making something similar. Enjoy
minor details i was dying to see if they would work and what they would sound like and also it seemed like a crime to drill a hole through the outside fiberglass of my brand new boat but i'm doing in the offseason
i bought the speakers at a flea market so i didn't pay more than $75 for both sets of speakers and the aluminum pipe and square tubing came from a valve manufacturing company (through a friend of mine) so the project was fairly cheap, i couldn't stand to spend $800-$1000 on the same set up pre - built if you can find people willing to give you the aluminum tubing, it can be cheap
Here's some pictures of my home built enclosure with Pro Audio components. It definitely rocks. Looking for a mold expert to take it to the next step.
It is a hybrid construction of fiberglass and aircraft quality components creating a very structurally sound enclosure. The loaded weight of it is about 63 lbs, but that should come down a bit with more refining.
depoint50ae, i'll try and get some this weekend to put up, it's just clear fiberglass that we cut into the circle and then cut a smaller ridge on one side, about half the fiberglass, so it would sit inside the aluminum tube, then just used some countersincted screws to keep it, i'm trying to put some blue led lights inside the tube that could be seen at night for a cool effect, but haven't got to it yet
