slot vs aero AGAIN!!

[Skip01 5,000+ posts]

You can make a box sooooo much smaller, externally , with aeros.

Its almost impossible too do side by side test really.

Title FAIL! A piece of PVC is not an aero-port.

The reason I use it is due to size constraints and simplicity. An external aero port is easy to calculate for tuning, and can worm through weird spaces in an attempt to achieve optimal box volume, port area, and port length. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

can you figure out aero "math" calculations easily then?

i REALLY need some help figuring out some aeros length/diamater.

This box is 4.5 ft 8" aero and its one of the 10 best sounding subs i've heard. Hatchbacks are amazing.

Its on an AQ 1200D we clamped it at 1000watts D2 wired parallell 1 ohm rising to 2.6 ohms! sometimes 3!

the size of the box is the only thing that matters for port size right? cause i had 3 10's in mine.

No I believe to choose port area you have to factor in total power and xmax, cone area, what the sub likes. Thats what I do it works great every time. If This box was for 3kw I might do even more port area like two 6's. But more port area usually brings down SQ. Depends what you like.

Like A box for two 10" HDC3's would need 14-15 sq inches of aero per cube,8" in 3 cubes but if it was for say two concepts getting 250 rms, 2.8 cubes and 6" aero would be fine. When you have aq's in the big port area boxes they do sound different at low to mid volume but when you get them going they sound great, very powerful. If you dont want that sound at low volume then cut the port area down and it will help over all SQ - to a point.

Things that determind port length.

1) box size

2) tuning frequency

3) size of the port

4) number of ports

There are so many industries that have used flared and contoured edges to flow things 2x - 3x what they could before they implemented the technology. Inside the tips of diesel injectors each of the spray holes on the nozzle have flared edges internally to get more flow through a smaller hole. They do this by drilling the holes in the nozzle (about .035 inch drill bit i think) and then pumping silly putty with diamond dust through the nozzle wearing down the edges of each hole.

let me re word that! does the amount of cone area count at all?

Which is best depends on the box design. Some boxes are louder slotted (like walls) and most street boxes are louder with aeroports. It really depends on the the application.

thats because your taking advise from makeshift audio on box building. that guy fixes amps.

what kinda subs are you running? because the best designs ive seen and heard is with the subs firing foward and completely sealing off the trunk from the cabin. with a slot port on the driver side firing foward.

i got a 2000 watt amp.cut the port and it does sound better. but i think i need a bigger box. i'm gonna try 2 in 4.5. what size round port? 2 6's? make a elbow for a 10?
