Round over bit to make an aeroport flared?

[EPerez 236]

I want to use 2 6" or 1 8" for my next box since it will allow me to tune lower and also give me more internal space using the same dimensions. But on the face of the box I can't actually use a flare like the one Adrian has or the ones that partexpress sells, because it won't fit. Now can I use a round over bit on the port opening of the wood to make it a flare? Pic below is how I made a box for 4 15s and I had 4 6" pvc pipes. It's double baffled. The front baffle was used as .75" of the port length since the pvc didn't go all the way out of the box. It only went into the inner baffle. So can I use a round over bit to make the outer baffle a flare by using the bit? I'm not sure how big of a bit I would use, but a little flare is better than nothing right?

Just use whatever size you think. Port area is more important than the roundover. I use 3/8" on my projects.

[EPerez 236]

Well 2 6" is ~56in2 of port area and 1 8" is ~50in2 of port aero. Wouldn't it make it more efficient or better somehow if it is flared?

Flared should help with port turbulence but I have never had a problem with straight aero ports

So should I just try it straight first and then if there is any port noise should I then use a router to flare them?

[S.DeYoung 968]

yeah or flare them for the look, trial and error

[EPerez 236]

I think I'll just flare them for the look anyways. I've also been reading it's best to do 1 single aero port vs multiple. How come? So would 1 8 be better than 2 6s?

crazy... that guy ^^ knows so much

I know I just wish I could understand it haha

I think I should buy that book, probably answer a lot of my questions. Thanks Quentin.

Best book you could own for audio. I refer to it daily.

[S.DeYoung 968]

What woofers and power is the question for?

I recently picked up a copy. Gonna put in on my tablet to read when i poop

[EPerez 236]

I'm gonna put an saz2500 to 2 sundown X 12s.

remind me not to borrow your tablet

going to be a pretty small port for those woofers. High Xmax and small ports dont mix well but if you are limited to space and enclosure size, it doesnt hurt to try

[EPerez 236]

2 6" aeros wouldn't be enough? I thought it would be pretty good.

[S.DeYoung 968]

Not even half of the minimum recommended port area

What would you recommend for port area then?

Or what size aero?

Can you squeeze a 10 in there? That would get you closer

[ricksi30 923]

Yeah I would use more port area for sure, a slot port would probably make it easier to get more.

[EPerez 236]

I cant put a 10 since the width is only 35". Does using aeros lower the amount of port area needed? If so how much? How much port area do you guys recommended needed? I want to tune to 29hz.

[EPerez 236]

Jacob was using a 6" aero for the box for the 12" z v.4 on a saz3500 at .5 ohms. He said it was doing good with it like that. Doesn't the X need less port area than the z v.4?

[skittlesRgood 3]

my mayhems I talked about in the other thread were in a box that was just under 5 cubes, two 6" PSP ports, tuned to 38hz. with a clamped 3200w it did a 150.4 legal. so I'm going to say that two 6" aeros isn't way too small. i used to know more information on the size of the flare and it's performance but I recommend you either grab those PSP ports or make the roundover as big as you can.
