Just saw these.

FRIGGEN COOL!

I may just have to get a circular saw for my BTL box.

It's only flared on one side. I don't see the point.

I don't see the point.

Looks, I guess. Doesn't look all that good to me either.

Only flaring one wide would still be 50% better than not flaring either.

You can alse bend the inside wall, so there would be much less turbulance at the inside corner (of an "L" port) than there would be otherwise. Add something to the opposite corner and it's a completely bent (radiused) port.

Yeah, and this doesn't take an advanced engineering degree to design.

but that port isn't even flared 50%....more like 35%. he's only flaring one side of a four sided object, and that's not counting the rear of the port inside the box.. i don't see where there is really any gain at all, and flaring it like that on one side looks dorky.

the center console was kinda neat though....

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

But those boxes that take "an advanced engineering degree to design" actually have some acoustic benefit of some kind

I don't see the point in flaring a slot vent anyways. Unless it is necessary to make the vent so small for tuning purposes that you don't get the necessary vent area, the turbulence will be well within range for vent mach. Even in an SPL setup you are gaining minimal amount, if any. It will only help in that instance. It does look different, that's for sure.

dude said 1db.

The increase in cross sectional area will have a diffusing effect, even though it is only on one side. It will improve flow and reduce port speed at the exit point which can help out a lot in the realm of port noise. Say the port is 3" wide and the single sided flare is a 3" radius. You've doubled cross sectional area and halved velocity at the mouth of the port. Same priciple as a full flare on a round port. You do have to account for the volume of air in the flare though.

the things i would give up/ do for that cnc router!!

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Thats a small table...I run a 5x10 for a sign company.

While i have cut box pieces on the table, I had never thought about stacking like that dude did..

Looks like i'm gonna be doing a lot of reading and math today...

[mrray13 30]

lol..man i wish we had a cnc router when i worked for a sign company. if we did "routed" aluminum faces, we cut it out by jigsaw. my current employer, stereo shop, is considering sear's small cnc router for doing trim pieces and such.

i, too, am wanting to do a laminated enclosure. but i don't have a router table, lol. it'll be all hand routered.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[weasle421 1]

We aren't a small compay...... henrysignsystems.com

i hand to talk my bosses out of getting another table

if you were closer we could probably work something out...

laminated and cut by hand is a lot of work, but would be worth it

what i love the most is we keep 3/4" HDF around to make molds for panformed faces

now if i just had the time and $.....

we used 2x4s and 1/8" masonite for our molds. i used to work for coast to coast sign company. there was a few times we used 3/4" or 1" hdf for faces, but mostly it was the 2x4/masonite combo. i miss the 10' chain arm saw(like a real big radial arm saw, only it was pulled by a chain attached to a crank). lol, cut rip a sheet of wood in half in about 2 seconds, lol.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
