I had a bunch of MDF lying around and I got a new router bit so I decided to make a humongous port from multiple layers of mdf rings. The inner diameter is right around 10.75" and it flares out to 15" The mounting flange makes it 17" in diameter. I still have to finish the other flared end. The port will be 19" long.

Lots of bondo glass. Just need to add about 4 more inches of mdf rings and the other end flare and it'll be finished!

yeah, it is. I would have had most of it done in about 3-4 days if I didn't have to work crazy hours. So far, this has taken about a week and half.

yah, I didn't want to go with a regular slot port because everybody and their brother has a large bass reflex with a slot vent enclosure. Plus, tubes are better for airflow.

I love the shameless plug for Mach 5 when taking pics of your port.

Good stuff, but they need to price them where us broke Americans can afford them.

Very cute work though, sonny.

?????

Do you comment on everyone else's threads where a particular company's product is in their pictures? And why should mach 5 have to cater to yor broke lifestyle? They're priced very well compared to most other companies...

Would you rather have the port size referenced to something you can afford? I have an Xplod lying around somewhere. Maybe a stack of food stamps? Thanks "pops"

The actual displacement must be nuts, though. That's a strong port, though. :crazy:

I don't remember if I have 5 or 6 of them lying around but I think I'm going to hold on to them. Once my sister gets a car, I'll probably use them for her setup. I almost wouldn't feel right selling these anyway, the couplers are pretty messy with glue and they look kind of skanky :P

Yeah, I'm going to try several boxes; one with the port internal and one external (of course I'll lose my back seats) I'm trying to make this into a solid 49 bass racer. who knows...

Holy fawk dude! That thing is ****. Your gonna paint it up all nice and smooth I assume, what color? What box and tuning is that all for?

ContourSPL
11-04-2008, 09:52 PM
The planned box will be 5.5 cubes tuned to 40 hz. Going in my 98 Jeep Grand Cherokee. The port is pretty **** big for 2 12's, I know. I might upgrade to a pair of 15's down the road. I haven't decided if I'm going to paint it yet. As long as it's smooth, I'm okay with it. SPL/bassrace ain't always pretty :) If I do paint it, it'll be red

Ok I gotcha. Thats gonna be pretty sick no matter which way you end up lol. I would some nice paint on that bad boy and make it the center point of the system lol

Awesome job man... looks good. I recently did something similar... but never thought to use bondo and wider rings to get a larger flare. Now I'm rethinking mine. Mine is only 6".

noice. Saw that on PWK. To get an even better flare, you could use different thickness of wood. Start with 3/4 then 1/2 and 1/4. I would still prefer a port like yours over a plastic one. Aeros and PSP ports are great but I like my ports to be solid with no vibrations. It was difficult to get a good flare instead of just an expansion but it came out pretty good. I still have to smooth it out a lot though, even on the outside. Time to bust out the belt sander.

That's the bondo brand body filler. The "higher end" kind compared to the grey kind. I couldn't find any rage around here so I went with this.

Duke
11-04-2008, 11:18 PM
I don't remember how thick mine is, but it doesn't vibrate and there is zero port noise. Its awesome. I'm definitely going to try something like you've done here, but for a larger sub soon.:)

For everyone wondering, the port weighs 24.6 lbs according to my digital bathroom scale

Yeah, it took way too long for what it does. I had fun building it though, and it worked better than I had hoped it would.

I just used a single spiral upcut bit. Still works great.

how much does that thing weigh???

also.. .how many cuts around do you do before you get through the wood... It usually takes me 3-4 rounds

Duke
11-05-2008, 04:08 PM
I just used 1/4 spiral bits I got from Harbor Freight. They're good enough to go through 3/4" wood in one swipe and they last pretty long.

i see u used bondoglass , do u know if regular bodyfiller would work well to or does it need the fiberglass strands in it?

thanks

11-05-2008, 06:42 PM
fiberglass is always best to use first, don't do it with JUST body filler.... body filler or "bondo/puddy/mud" etc... is used for finishing only. that stuff breaks easily if applied to thick. I do a TON of body work and while it isn't exactly the same, the same principals apply.

I would use Long strand to start with, then short strand then filler... or skip the long strand like he did, depends on how thick and everythign you are going to have to apply it.

yeah, I used the bondo glass for strength and the regular body filler to smooth it out. Still have a lot of work to do on it still.

11-05-2008, 11:39 PM
Yeah... I'd use birch to make the flares... and then sonotube for the length

And glass or kitty hair to substantiate the gaps... then rage to smooth it...
